The existing bridge was converted to a four lane eastbound carriageway (including a hard shoulder). The new bridge formed the westbound carriageway. The entire stretch was lit with streetlights (the old section was not lit). The old Medway Bridge was physically narrowed by removing part of the footpath.

The road starts at a junction with the N12 in the city centre of Rennes. The road heads south west and is a dual carriageway. The old road is numbered the RD224 and passes through the town of Mordelles. Thereafter the road is an upgrade of the former carriageway.

Between the M25 and Honiton, the A30 is mostly single carriageway, carrying local traffic with short stretches of dual carriageway from Camberley to Basingstoke, which has a dualled inner ring road, two between Stockbridge and Salisbury (an alike ring road shared with the A36), and between Sherborne and Yeovil.

The conservation area surrounds the village green. The village is partially bypassed by the A244 which alternates here between a dual carriageway and a single carriageway. Upper Halliford railway station is on the Shepperton branch line and train services to London Waterloo are run by South Western Railway.

In 1890 a picket fence, high, was erected and painted along the Lane Cove Road (now the Pacific Highway) boundary. Four years later the General Section east of the Carriageway was redesigned for extensions to the Wesleyan, Presbyterian and Congregational sections. By 1899 an estimated 2096 burials had been performed at Gore Hill Cemetery. Between 1898 and 1900 the Carriageway was regraded and guttered, and a shelter shed erected and between 1900 and 1901 the Carriageway was surfaced with blue metal.

The A57 is entirely Single Carriageway in Lincolnshire, West of the A1 it is a trunk route, East of the A1 it is maintained by the local council. Other important routes in Lincolnshire include the A15, A16, A17 & A158. The A15 & A16 run on the north-south axis, the with A16 being near the West coast, while the A15 being between the A1 and A16. Both routes are almost entirely single carriageway with small amounts of dual carriageway in built up areas.

On entering the Borough of Milton Keynes, the road becomes an (almost) fully grade-separated dual carriageway and passes through Milton Keynes. This stretch was opened in 1980, replacing the original route along Watling Street. From just north of MK, after entering Northamptonshire, the road resumes as a single carriageway that continues through Towcester where it crosses the A43 dual carriageway just north of the town. The road accompanies the Grand Union Canal and the M1 motorway through the Watford Gap.

The length of the A4234 is just and is entirely a two lane dual carriageway with clearway restrictions.

Until then, the tunnel had only a two-lane carriageway running east to west, which opened in 2002.

About of the westbound A18(M) carriageway was abandoned when the M180 was built on a new alignment.

The tunnel portion will be approximately five kilometres in length. It will carry a two-lane dual carriageway.

For many years predominantly single carriageway, a major upgrade of the road to dual-carriageway was completed in 2015 which grade separated all major junctions between Coleman's Corner roundabout and Larne. Beginning at junction 4 of the M2 motorway the road is under motorway restrictions as the A8(M) for around 1.6 km until it meets a roundabout at Corr's Corner. From this point the road is dual carriageway of varying standard for the entirety of its length, meeting roundabouts at Coleman's Corner and just before Larne. The Harbour Highway, bypassing Larne, is dual carriageway, and includes a grade-separated junction with the A2 and provides a direct link to the Port of Larne.

In the UK, although the term "dual carriageway" applies to any road with physically separated lanes, it is frequently used as a descriptive term for major routes built in this style. Such major dual carriageways usually have two lanes of traffic in each direction, with the lane nearest the centre being reserved for overtaking. Occasionally dual carriageways have only one lane in each direction, or more than two lanes each way (sometimes to permit easier overtaking of slower uphill traffic). Different speed limits apply on dual carriageway sections from those that apply on single carriageway sections of the same class of road, except in cities and built-up areas where the dual carriageway is more of a safety measure.

There are some higher-capacity (i.e. not just single-carriageway) sections of regional road, most notably the R113 (Belgard Road) and R445 (Old Naas Road), R132 Swords Inner By-pass and R136 Dublin Outer Ring Road which have sections of dual carriageway. In some cases, important high-capacity urban routes are built or designated as regional roads, such as the mostly dual-carriageway R710 Waterford Outer Ring Road, or the R774 Greystones to the N11 link, which is dual-carriageway for its full length. In many other cases, upgraded regional roads (for example, wide two- lane roads) were previously part of a national primary road, prior to the construction of a motorway or other bypass.

On reaching the valley, it reverts again to single carriageway and through the village of Chicklade, before following the terrain over to Mere, where it runs north of the town as another dual carriageway bypass. Continuing west, it passes south of Wincanton and then north of Sparkford to a roundabout where the road reverts once more to single carriageway. The western end of the A303 is a lower standard of road through the Blackdown Hills The road then bypasses Ilchester and RNAS Yeovilton and widens to dual carriageway again. Between Ilchester and Shores Bridge (over the River Parrett, east of South Petherton) the road follows the course of the Roman Fosse Way.

The road continues as dual carriageway, crossing the Doncaster to Lincoln Line, with the former road being Ramper Road to the south, and becomes the single carriageway The Flood Road, on the former route, being the Beckingham-Saundby parish boundary. Approaching Gainsborough it passes the Crown Carveries Trent Port Inn.

Section between A4 junction and Trakai is planned to be controlled-access. Short section between Birštonas and Prienai is converted to dual carriageway. Turbo roundabout was implemented near Birštonas.

The M25 has had problems with animals or birds on the carriageway. In 2009, the Highways Agency reported that they were called out several times a week to remove a swan from the motorway around Junction 13. There have been several reported accidents resulting from horses running onto the main carriageway.

Traffic wishing to turn out of the side road, simply cross the intersecting carriageway and drive up the other 'wing' of the seagull, and merge onto the other carriageway. ;Sealed road :A road on which the surface has been permanently sealed by the use of a pavement treatment, such as bitumen. ;Self-driving car, autonomous vehicle, or driverless car :A vehicle that is capable of sensing its environment and moving safely with little or no human input.

The A631 used to continue to the east as a trunk single-carriageway, but was upgraded to dual carriage way to the A618, and is crosses by the Rotherham Roundwalk. The West Bawtry Road Improvement - Rotherway to Whiston Crossroads was built by Birse Civils of Barton-upon-Humber for £5 million.Rotherway to WhistonWhiston Improvement 2006 The A631 is now dual-carriageway between the M1 and M18 junctions Brecks The A631 then continues round Rotherham crossing the A618, becoming the dual-carriageway East Bawtry Road.

An additional 8 km is to be upgraded at some future date and redesignated as A6. The section between Elbląg and the border with Russia was completely reconstructed and opened as an express road, S22, in September 2008. In the course of the upgrade, the new modern carriageway was built in the space left for the second carriageway during original construction. At the same time, the original concrete carriageway was demolished almost along the entire length of the route, and only a few traces of it remain.

Looking along the M6 to the junction with the A601(M). The A601(M) is a motorway in Lancashire, England. It is long, and meets the M6 at Junction 35. It was a unique motorway within the United Kingdom as it had a dual carriageway section leading north from Junction 35 of the M6, with a single carriageway section (one of the only 3 single carriageway sections with motorway status in the United Kingdom) leading south, where it terminated at a T junction on a B road.

The upgrade to class II bitumen and widening to double carriageway will be jointly funded by the European Union and African Development Bank. The construction cost is budgeted at US$751.3 million, with 70 percent borrowed from the AfDB, and each country funding 30 percent of the work in its territory. In April 2018, the Business Daily Africa newspaper reported that construction delays on the Kenyan side were attributed to changes in road design from single carriageway to double carriageway, along a section of the highway.

Where space is even more limited, intersections may be controlled by traffic lights. Smaller residential roads adjoining urban dual carriageways may be blocked off at one end to limit the number of junctions on the dual carriageway; often other roads will pass over or under the dual carriageway without an intersection. A dual carriageway with grade-separated junctions and which meets other requirements may be upgraded to motorway standard, denoted by an (M) added after the road number (e.g. "A1(M)" or "A38(M)").

These signs contain a code which can be given to the emergency operator or the RCC to locate you quickly. For example, a sign may say "M1 A 100.5". This translates as the M1 motorway, on the "A" carriageway, at 100.5 kilometres from the M1's nominal start at the North Circular A406. The "A" and "B" carriageways are designated by Highways England to each carriageway, dependent upon which direction it travels; these normally refer to whether the carriageway goes "Away from London" or "Back to London".

The majority of the A36 is built to single carriageway standard, but parts of it have been upgraded to dual carriageway. The A36 is dual carriageway for its 1 mile (1.6 km) bypass of the village of Beckington, 3 miles (5 km), briefly combined with the A361 north of Frome. It shares part of Warminster bypass with the A350. It is also dualled for approximately 1 mile (1.6 km) near its grade separated junction with the A303 road, 8 miles (13 km) north-west of Wilton.

Service Lane on Bangalore elevated tollway on Tumkur Road, Bangalore. In India, frontage roads or Service lanes (sometimes called नल्ला "Nullah" in Hindi) exist on most high density dual carriageway roads and dual carriageway highways. On Access controlled Expressways like the Yamuna Expressway, the frontage roads remain separate from the main carriageway throughout the road's length. Retrofitted and previously non-access controlled roads, such as most National Highways, only have service lanes on stretches where fly-overs (overpasses) are built over junctions or through towns.

The westbound carriageway loses a lane, remaining three lanes for the rest of the route, and the London-bound carriageway gains a lane. The motorway then immediately crosses the valley on a large ramp-like bridge. J4 is the interchange with the A404, for High Wycombe, Marlow, Maidenhead, Reading, Windsor and the M4.

When a "third" carriageway is added, sometimes it can shift a directional carriageway by (or maybe more depending on land availability) as a way to retain private access on one side that favors over the other. Other methods involve constructing a service drive that shortens the long driveways (typically by less than ).

Today SS4 is a busy road between Rieti and Passo Corese, as it is the main road link between Rieti and Rome; motorists use it to reach the Autostrada A1 in Passo Corese and continue towards Rome in the more modern road. In this trait SS4 has a single, albeit reasonably wide carriageway, which was constructed in the 1960s in place of an earlier, less smooth road. For this reason, Italian Government plans to make SS4 a dual carriageway road between Rieti and Passo Corese, but around 1.5 billion euros are neededCamera dei deputati - Sistema Informativo Legge Opere Strategiche and it is not known when funds will be granted. Uprating of the trait from Cittaducale to Posta, where the carriageway is rather narrow and the road climbs up the Apennine mountains, is also planned to make the carriageway wider and less winding - even if the road will remain with a single carriageway.

Whitfords Avenue is allocated State Route 83 east of Marmion Avenue, and Tourist Drive 204 (Sunset Coast Tourist Drive) between West Coast Drive and Northshore Drive. It is a four lane dual carriageway east of Northshore Drive, as well as between Hepburn Avenue and Northside Drive/Tenerife Boulevard, and is a two lane single carriageway in the remaining stretch between, though there is a section between the Pinnaroo Point entrance road and Flinders Avenue that is a two lane divided carriageway. Whitfords Avenue commences at a roundabout, with the entrance to the Hillarys Boat Harbour to the west, Hepburn Avenue to the east, and West Coast Drive to the south. The road starts off as a four-lane dual carriageway, with the northern section of Hillarys Boat Harbour to the west and residential development to the east, reaching Northside Drive and Tenerife Boulevard later, after which it promptly reduces to a two-lane single carriageway.

The South Circular Road starts just south of the ferry terminal where the A2204 Ferry Approach meets the main east-west road through Woolwich, the A206. It heads south, climbing up John Wilson Street, a section of dual carriageway, until it meets Grand Depot Road and becomes single carriageway through Woolwich Common and Academy Road past the former Royal Military Academy. The route continues south to the A2 at a grade separated junction—one of only two on the route—and continues southwesterly as a dual carriageway, crossing Eltham Road (A210) and Sidcup Road (A20). At the junction with Burnt Ash Hill the road becomes urban single carriageway again, which it remains the case for most of the remainder of the route.

On 18 July 2019, 4 km of dual carriageway road were officially opened as part of the M11 Gorey to Enniscorthy PPP Scheme. The 8 km of single carriageway road were opened on 14 August 2019. N30 east of Clonroche, looking east On 29 January 2020, a 5 km segment of dual carriageway, roundabouts, and a 1.2 km single carriageway were officially opened as part of the N25 New Ross Bypass PPP Scheme, which also forms part of the N30. This has replaced the westmost 8km of the former N30 road between Corcoran's Cross and its former terminus with the N25, and the road's segments have been redesignated as either wholly or partly as regional roads or local roads after the opening of the scheme.

The first part of the six-lane motorway to be completed east of Zagreb was the section between Ivanja Reka and Lipovljani, immediately to the east of the present day Lipovljani rest area; this was done in 1980. In order to maintain the flow of traffic on the Zagreb-Belgrade road during construction, the southern carriageway was completed first, and then the two-way traffic was rerouted to the new carriageway while the old, northern carriageway was widened and its pavement structure was replaced with a new one. Similarly, as the new carriageway extended further eastward, the at-grade intersections were replaced by interchanges or flyovers. In 1985, the motorway was extended by to Okučani, and in 1986 by another to Prvča, near Nova Gradiška.

Throughout the Sunderland section it is known as either Durham Road or New Durham Road, and is one of the major routes in and out of the city. A single carriageway section runs from the city centre to a large roundabout at the Barnes. The road then climbs a steep hill toward High Barnes, alongside the Bede site of the Sunderland College before becoming dual carriageway. Beyond a set of traffic lights at the Prospect Hotel, the road remains dual carriageway, but the inside lane is a 'no car lane'.

Great Eastern Highway commences at The Causeway, a river crossing that connects to Perth's central business district. Travelling north-east through the city to Greenmount Hill, and following a steep climb, the highway heads east through Western Australia's Wheatbelt to Kalgoorlie, in the state's Goldfields. Within Perth, the highway is a six-lane dual carriageway from The Causeway to Tonkin Highway near Perth Airport. It travels as a four lane single carriageway to Midland, with the second carriageway reappearing after Roe Highway, and continuing all the way to The Lakes at Perth's eastern fringe.

From here, the A92 runs parallel with the A90 for around 2 miles. The road then continues past Stonehaven and Portlethen heading into and through the city of Aberdeen before terminating at Blackdog, where the road once again merges with the A90. The 16-mile section of the road from Dundee to Arbroath was upgraded to dual carriageway standard in 2005 and significantly reduced the journey time between the two towns. Between Arbroath and Stonehaven the road is a single carriageway apart from a very short section of dual carriageway near Gourdon.

The N4 was the only one of the main inter-urban national routes whose dual-carriageway section continued into the city centre; however, the section inside the M50 was re-classified as the R148 in 2012. Heading west, the PPP motorway section (see below) ends west of Kinnegad, and the motorway terminates 5 km further west; it continues as HQDC and bypasses Mullingar. From the Mullingar bypass to Edgeworthstown, the road is wide single carriageway with hard shoulders. Between Edgeworthstown and Longford, there is a lower standard single carriageway road.

Clara Barton Parkway outside Washington, D.C. A German dual carriageway in the 1930s A dual carriageway (British English) or divided highway (American English) is a class of highway with carriageways for traffic travelling in opposite directions separated by a central reservation. Roads with two or more carriageways which are designed to higher standards with controlled access are generally classed as motorways, freeways, etc.

Where the A10 bisects Cheshunt as an urban dual carriageway, it is prone to traffic congestion, in particular because of the many junctions with local roads. In the early 1990s properties beside the road were compulsorily purchased for a relief scheme that involved sinking the road below ground level through Cheshunt and converting the original alignment to single carriageway for local access. However, in the wake of protests against a similar scheme in Wanstead, this was dropped and the road remains a dual carriageway, with surrounding houses having been sold back to private buyers.

The A34 dual carriageway serves Oxford and is a trunk route for Newbury, Winchester and Southampton (via the M3) as well as the rest of the South Coast — for this the reason it is part of the unsigned European route E05. The A41 dual carriageway serves Bicester and Aylesbury, and both roads meet the motorway at Wendelbury roundabout junction. This junction design is very inefficient and cannot cope with a very large volume of traffic using the junction. To try to alleviate this problem, there is a temporary lane drop for the London-bound carriageway.

A further stretch of dual-carriageway is provided on the border of County Londonderry and County Antrim near Macfin, including the first of many crossings of the Belfast-Derry railway. On reaching Ballymoney, the A26 route skirts past the town, and meets the B62 Ballybogy Road towards Portrush at a roundabout.

The route then becomes single carriageway before passing Stonehenge itself. The presence of the road through a World Heritage Site has been controversial for decades. After Winterbourne Stoke the route once again becomes dual carriageway from Yarnbury Castle and across the Wylye valley, meeting the A36 at Deptford. There is then another section of single carriageway road, coming out of the valley and up to the crest of the Great Ridge, before a further section of dual two lane road down from the hill crest near Berwick St Leonard.

A bypass of Marsh was opened in 1976; it was (and remains) the only dual carriageway upgrade of the A303 through the Blackdown Hills. By the mid-1980s, the A303 had been extended from its original fork by Micheldever Station, next to the A30, eastwards to meet the M3 motorway, and was a completely uninterrupted dual carriageway westwards as far as Amesbury. Ilminster was bypassed around this time; however the new road was built as single carriageway with 3 lanes, which caused a serious safety hazard leading to several fatal accidents.

Sign informing motorists of an upcoming section of dual carriageway in Seacroft, Leeds When first constructed, many dual carriageways—including the first motorways—had no crash- or other barriers in the central reservation. In the event of congestion, or if a driver missed their exit, some drivers made U-turns onto the opposite carriageway; many accidents were caused as a result of their misjudging the speed of approaching traffic on the other carriageway when doing so. The majority of dual carriageway roads now have barriers. Some are heavy concrete obstructions which can bounce a vehicle back into the path of other traffic; others are made from steel ropes mounted on moderately weak posts, where the rope cuts into the vehicle body to slow the vehicle while keeping it against the barrier until it has stopped.

The N11 has been gradually upgraded from single to dual carriageway standard from the 1950s to the present, with improvements taking place at an accelerated pace in recent years. The first short stretch of dual carriageway on the road, and the first stretch of dual carriageway in the Republic of Ireland, was built in the 1950s between the Stillorgan Road/Newtownpark Avenue junction (White's Cross) and Foxrock Church (this stretch was substantially widened around the turn of the millennium). Subsequent short stretches of dual carriageway, at Loughlinstown, between Bray and Kilpedder, and from Donnybrook to Stillorgan were constructed during the early to mid-1970s, this phase ending with the opening of the Stillorgan bypass in October 1977. Since that time, these sections have been joined up through further improvements.

The remaining single carriageway sections from Gort to Claregalway have been upgraded to motorway standard and were officially opened on 27 September 2017.

Stage 1 was the Douglas Arterial Road, which opened April 2005. It was in initially a two-lane single carriageway, prior to 2012.

Construction of the dual carriageway Dawesville Bypass around eastern Dawesville, south of Mandurah, began in late 2000, and was opened in July 2001.

They straddle the southbound carriageway of the A23 just outside the city of Brighton and Hove and are individually listed at Grade II.

The dual-carriageway A674 goes to Blackburn via the nearby junction 8 of the M61 and the Preston England Temple, a Mormon temple.

A bypass of Castlebar of dual- carriageway standard was approved by An Bórd Pleanala in July 2014, and construction began in late 2019.

Llanyrafon lies to the east of the Afon Llwyd and Cwmbran town centre, west of the A4042 dual carriageway and south of Croesyceiliog.

The Pleasley area is situated around the main A617 road. The Pleasley Hill section is a steep, old winding single-carriageway which was scheduled for an improvement scheme designated Pleasley By-pass Extension, a Nottinghamshire County Council initiative intended to link the A617 Chesterfield Road North and MARR junction to the existing Pleasley By-pass, a long-established dual- carriageway created by Derbyshire County Council which terminates on the Nottinghamshire side at the base of Pleasley Hill. The intended extension situated on the Nottinghamshire side has never been scheduled, and remains as a 'missing' section and bottleneck to the MARR route. Three proposals were mooted in 2004 with two alternate routes: # A single carriageway upgrade of the existing Pleasley Hill route # A single carriageway extension from the MARR junction at the top of Pleasley Hill routed through land running at the back of the old cemetery # A dual carriageway extension from the MARR junction at the top of Pleasley Hill routed through land running at the back of the old cemetery.

The A595 is a primary route in Cumbria, in Northern England that starts in Carlisle, passes through Whitehaven and goes close to Workington, Cockermouth and Wigton. It passes Sellafield and Ravenglass before ending at the Dalton- in-Furness by-pass, in southern Cumbria, where it joins the A590 trunk road. The road is mostly single carriageway, apart from in central Carlisle, where it passes the castle as a busy dual carriageway road named Castle Way, and prior to that as Bridge Street and Church Street, where it passes close to the McVitie's or Carr's biscuit factory. The Lillyhall bypass is also dual carriageway.

Plans have been published for a new road between the southern end of the Flimwell bypass and the beginning of the Robertsbridge bypass. The 5.5-mile (8.9 km) improvement will bypass the villages of Flimwell, Hurst Green and Silver Hill. The improvement will commence at the B2079 junction (Lady Oak Lane) on the short section of existing dual carriageway north of Flimwell and terminate at the roundabout at the northern end of the Robertsbridge Bypass. Although part of the road will be brought up to a dual carriageway standard, parts will become a 'wide single carriageway'.

The bridge was widened, with the west bridge, to dual-carriageway as the A614 as part of a £3.2 million section, opening in 1972. This was the completion of the dual-carriageway Nottingham ring-road. It enters the borough of Rushcliffe where it crosses the former Great Central Main Line and meets the A60 (for Ruddington and the Nottingham South Premier Inn), then the A606 at busy roundabouts. This section from the A606 roundabout, near the Wheatcroft Garden Centre, to the Dunkirk junction (current A6005, then the A453) - the Nottingham Ring Road - was opened in 1963 as mostly single carriageway.

The Deeping bypass crossing the Roman Car Dyke (the vehicles photographed are on the bypass) The route turns left onto the dual carriageway Deeping Bypass, sharing the road with the A15 Peterborough to Bourne highway, as far as the roundabout for Bourne Road to the north of Market Deeping at TF131112. From here the A15 departs northwards, and the A1175 heads east, reverting to single carriageway, having the bypass to itself. At TF135114 it crosses the Roman Car Dyke, two examples of civil engineering built nearly two millennia apart. The dual carriageway ends at TF171127 having bypassed Market Deeping and Deeping St James.

Expressway S69 or express road S69 (in Polish droga ekspresowa S69) was a major road in Poland which was supposed to run from Bielsko-Biała to the border with Slovakia at Zwardoń/Skalité, where it would connect with Slovak motorway D3. In the original plans, from Bielsko-Biała to Żywiec, the road was to be a dual carriageway with the remaining part to the border with Slovakia a single carriageway only (with terrain reserves for construction of second carriageway in future). Since August 2016, the S69 is part of expressway S1.Rozporządzenie Rady Ministrów z dnia 19 maja 2016 r.

The A74 was the original route from Glasgow to Carlisle where it met the A7 which meets in Carlisle city centre the A6 south to London. Starting in the 1930s, the single-carriageway road between Gretna and Glasgow was progressively upgraded to dual carriageway, being completed in the early 1970s with the completion of the Gretna bypass. At the northern end, it was not possible simply to add to the existing carriageway because of the built-up nature of the area. A bypass was built as one of Scotland's first motorways, the M74, from Draffan to Maryville, north of Uddingston, completed by 1969.

The route starts at Thornaby Road with a junction on the A1044 road going eastwards towards the A19 road. This section was single carriageway, but it was upgraded as part of the long- term plans for the area. After the junction with the A19, the route cuts across South Teesside taking an east/west cut past Normanby, Ormesby and Eston to a junction with the A1053 road to Grangetown. It is here that it loses its Trunk Road status (this carries on up the A1053), but the dual carriageway A174 continues east towards Yearby before becoming a single carriageway.

The section of A338 between the A31 dual carriageway at Ringwood and Salisbury's A36 Churchill Way is built on a substandard single carriageway alignment with multiple sharp bends as the road follows the line of the River Avon. This section of the road has a poor safety record; it is heavily trafficked and the resulting risky overtaking is responsible for a number of head-on collisions. Following four fatal head-on collision accidents in 2008 alone, local residents have renewed their calls for the road to be upgraded to dual carriageway to provide a safe overtaking facility and deal with the capacity problems.

The road starts at junction 10 of the A14, heading past Wicksteed Park and into Kettering. Through the town it is a single carriageway until crossing the A43 at a signal-controlled roundabout. From here it passes an industrial development and heads north towards Corby. The stretch between the A43 and the A6014 road in Corby is the only length of dual carriageway on the route. As at July 2012 a bypass is under construction from Barford Bridge on the A6003 to the A43 west of Stanion to relieve the traffic on the single carriageway passing through Geddington on the A43.

Airbles is a small suburb to the south-east of Motherwell, North Lanarkshire. It is mainly a residential area, consisting mostly of a mixture of high-rise and low-rise flats. The dual carriageway, known as Airbles Road, passes through the suburb. It is hoped that in future, the dual carriageway can become a link road between the M8 and the M74 motorways.

Freeway 1 () is the first and longest freeway in Iraq. It is long. It extends from Umm Qasr Port in Basra to Ar Rutba in Anbar, where it spreads into a new freeway with same number towards Syria and Jordan. The part of the freeway from Nasiriyah to Al Diwaniyah is a single carriageway, because the second carriageway is not completed.

The project was to build a single carriageway road, with crawler lane along part, linking the A354 Manor Roundabout near Radipole to the A354 at the top of the Ridgeway Hill. The main carriageway of the Weymouth Relief Road opened on Thursday 17 March 2011. The 2012 Olympics at Portland played a major factor in making £89m funding for the road available.

N22 approaching Cork South Ring (N40) from the north. A High-quality dual carriageway (HQDC) is a road category in Ireland. It is defined as an all- purpose dual carriageway road type built to near motorway standards, but without motorway classification or motorway restrictions. High-quality dual carriageways have full grade-separated access and do not have junctions with minor roads.

The line closed to passengers in 1953 and goods in 1960. The town sits on the historic turnpike road between London and Norwich, which later became the A11. The first bypass opened in 1968, followed by a second in 1987. A high speed dual carriageway link from Thetford towards London opened in December 2014, which removed the remaining of single carriageway via Elveden.

Siedlce (, ) is a district (dzielnica) of the city of Gdańsk, Poland, with 17,584 inhabitants (area 2.6 km²). It includes the area around Kartuska Street, the main road out of Gdańsk towards Kartuzy). Recently, a new dual carriageway, Domestic Army Avenue, was built along the boundary between Siedlce & Chełm. This was built as a bypass to the single-carriageway Kartuska St. for intercity traffic.

As of May 2016, following a sustained upgrade program, 437 kilometres (65%) of the highway between Hexham and the Queensland border was dual carriageway (either at freeway or arterial road standards), with 240 kilometres of single carriageway remaining to be upgraded.Pacific Highway upgrade Roads & Maritime Services May 2016 The coroner also recommended research into coach seats, seat anchorages and seatbelts.

Its construction began in the 1970s near Paris. The first section between Paris's Porte de Bercy and Joinville-le-Pont opened in 1974 with a single carriageway. A second carriageway was added in 1975, and the following sections between Joinville and Metz were opened in 1975 and 1976. Former autoroutes A32 and A34 were integrated into the A4 in 1982.

From Middelburg to Belfast the N4 is a single-carriageway highway with two lanes in both directions; thereafter, the N4 is a wide shouldered single- carriageway highway. The section east of Middelburg has been significantly improved, including a northern bypass of Mbombela, and now features some new grade-separated junctions. The N4 east of Pretoria forms part of the Maputo Corridor Toll Route.

This project will comprise a new 20km dual carriageway from Westport to the existing N5 near Turlough, bypassing Castlebar, as well as a single carriageway relief road around Westport and the realignment of 2.5km of the N59 road north of the town. An Bórd Pleanala approved the route in May 2014. Contracts were signed in October 2019 for the construction of the project.

The A160 starts at a grade separated junction at Rye Hill on the A180 at TA136144. No other road shares this junction. From the A180 the road is single carriageway to a roundabout on the edge of South Killingholme at TA147159. From there it becomes a dual carriageway straight through the village and the adjoining refinery, until the roundabout at TA169165.

The road then swings towards Wellington with a short section of dual-carriageway. The A49 then reaches Hereford, the only major destination on the road without a bypass. The road passes right through the city centre, causing serious congestion on both the north and south sides of the River Wye. The dual-carriageway Greyfrairs bridge over the Wye opened in 1967.

The London end of the Great West Road became Britain's first dual carriageway when it was opened in 1925 by King George V. In 1927 the Rome bypass was opened. It ran bypassing Rome to the east. Almost the entire length featured a dual- carriageway design. In the early 1930s it was extended southward all the way to Naples and northward to Florence.

It meets the B1444 where the road becomes a dual carriageway. It meets the A18 at a roundabout. This was the old terminus of the A46, and what is now the A46 heading east into Grimsby used to be the A18. The road becomes the single carriageway road once again and runs alongside the north part of the Lincolnshire Wolds.

The project cost $2.21 million and was funded by the City of Wanneroo. Construction started in February 2017 and was complete by August. Construction started in 2018 on upgrading Marmion Avenue north of Camborne Parkway, from the current 2-lane single carriageway to a 4-lane dual carriageway. The state government has allocated the City of Wanneroo $23 million to upgrade the road.

They were introduced to improve road safety. The final filter in turn is located at the end of Victoria Avenue. Traffic in both lanes where the dual carriageway reduces to a single carriageway must take it in turns to merge into the new lane in conditions of heavy traffic. These are accompanied by signs telling road users to use both lanes.

It becomes the dual- carriageway Worksop Road, and now the level of traffic increases as it is a major east-west route. It becomes single-carriageway and meets the B6463 from the left, near Todwick and Red Lion Inn. At South Anston, it meets the B6059 at the Shell Worksop Road station. It crosses a railway and Lindrick Common near Woodsetts.

It is dual carriageway throughout. The A289 was built in the 1990s as the Medway Towns Northern Relief Road. Constructed in three stages, firstly it bypasses Strood with a dual carriageway from Three Crutches (M2 J1) to the A226 and the A228 (The Wainscott Northern Bypass). It then joins the A228 (as The Wainscott Eastern Bypass) — these two parts are dualled.

The from Cardiff Bay to Merthyr Tydfil are mainly direct and good quality dual carriageway, but most of the route from north of Merthyr to Llandudno is single carriageway that has seen improvement in the last 20 to 30 years. The road travels through two of Wales's national parks; the Brecon Beacons, and Snowdonia National Park starting just south of Dinas Mawddwy.

Jalan Universiti is a major road in Petaling Jaya city, Selangor, Malaysia. It is the first dual-carriageway road built in Malaysia since independence.

The NZ Transport Agency began upgrading SH1 from the Andersons Bay intersection to Lookout Point to a four-lane dual carriageway in January 2011.

It crosses the Liverpool to Manchester Line (southern route). At Great Sankey, it becomes a dual- carriageway and meets the A562 at a roundabout.

Situated off the A2 dual carriageway at Sole Street/Gravesend junction. Along Henhurst Road towards Sole Street. The car park is on the left.

The terminus is located next to a slope on the side of Pok Fu Lam Road southbound carriageway near the intersection of Pokfield Road.

It becomes single carriageway and passes North Burlingham near the staggered White House] crossroads with the B1140. The three-mile £7.1 million dual-carriageway Acle Bypass opened in March 1989, which ends at a roundabout with the A1048 near a Travelodge and the Acle Little Chef, becoming the single carriageway New Road. From Acle, the road enters the Acle Straight which is nearly seven miles of straight and level single carriageway to Great Yarmouth, with just one curve at Road House Diner. The road is notorious for congestion, especially during the holiday season, and also for the number of accidents, which due to the drainage ditches on either side of the road are often fatal, and demands for dualling have been heard for many years, although there are no current plans to go ahead with this.

Aerial view looking south-west towards Shoreham airport. The aircraft hit the A27 dual-carriageway between the River Adur, in the foreground, and the runway.

The problem was remedied by closing one carriageway at a time and building a pair of 'land bridges' across the unstable section of the slope.

From there a short piece of single carriageway runs to the end of the public road at TA177166. The current route length is 3.2 miles.

His tenure saw the completion of the Lagos-Ibadan expressway, the Benin-Shagamu dual carriageway and the A2 road, linking Warri-Benin-Okene- Abuja-Kaduna.

The village has road links with nearby cities Derby and Nottingham, as well as the city of Birmingham, approximately south along the A38 dual carriageway.

There is another such interchange in Millvale, Pennsylvania, near Pittsburgh, at the junction between PA 28 and the 40th Street Bridge. The northbound carriageway of PA 28 passes under the interchange, with left-hand ramps meeting at the bridge (the northbound entrance ramp does not provide direct access to PA 28). The southbound carriageway of PA 28 has a continuous green T-intersection with the bridge.

Subsequently, preexisting dual carriageway of the Patras bypass and the National Road 8a section Elefsina–Corinth) were further upgraded to full motorway standards. of preexisting single carriageway in the Corinth – Patras section were doubled. of the southern A5 section (Patras–Pyrgos–Kalamata) will be newly constructed. The project was expected to take six years to complete, with a completion date scheduled for the end of 2014.

Double yellow lines in the UK indicate that parking is prohibited. Double yellow lines along the edge of the carriageway indicate that waiting restrictions apply to the road (which includes the carriageway, footway and verge). A driver may stop for passengers to board or alight and to load or unload (unless there are also 'loading restrictions' - see below). The regulation applies to all vehicles.

In February 2009, it was announced that the single carriageway Nantwich bypass would be re-numbered as the A51 in a bid to relieve the town centre of traffic. In 2015, the final 500m of the eastbound single carriageway between Weston and Junction 16 of the M6 was upgraded. This included resignalling works on the roundabout in order to relieve congestion at the roundabout.

Highways can be built either as dual-carriageway or two- lane single carriageway. Before the mid-1990s, there were no specific coding system for the expressways. When more and more expressways were built, a system of expressway numbering was applied to all expressways. Expressways are labelled with the letter "E" followed by assigned numbers, for example the code for North–South Expressway southern route is E2.

The Cork to Ringaskiddy road improvement scheme, originally envisaged as dual-carriageway, will now proceed as a motorway scheme M28 Cork to Ringaskiddy Motorway Scheme The planned Adare - Rathkeale dual carriageway, being progressed as part of the Limerick to Foynes improvement scheme, may proceed as a motorway scheme. This scheme is at the route selection stage and more details will become clear in the future.

The Carriageway is a mid-Victorian residential building. It consists of a pair of substantial two-storey town-houses of brick construction and terrace form with a central carriageway. The building is unusual in its roof form, the elevation to Smollet Street being composed of four equal jerkinhead gables. Other distinguishing features include stuccoes decorations such as quoinstones, gable plaques and elaborate window and door surrounds.

The A180 is a primary route in northern England, that runs from the M180 motorway to Cleethorpes. The road is a continuation of the M180, but built to lower specifications: it is mainly dual two-lane without hard shoulders. The road is (mostly grade separated) dual carriageway for from the M180 to Grimsby, and is a single carriageway road for between Grimsby and Cleethorpes beach.

The Newmarket bypass, opened to traffic in July 1975, is a dual carriageway. The western end is the A11, but most of its length is a multiplex/overlap with the A14. The A11 re-appears north-east of Newmarket, and remained a dual carriageway. The road bypasses Barton Mills before entering Norfolk in the Thetford Forest, passing the 113-foot-tall () Elveden War Memorial.

A47 and A11. The upgrading of the final section of single carriageway between Barton Mills and Thetford (opened December 2014) means the road is dual carriageway all the way to Norwich. The road continues northeast bypassing Thetford, Attleborough and Wymondham. The A11 originally ran through the centre of all three towns giving rise to congestion which frequently became the focus of delays on the route.

Plans are still proposed for upgrading this later. The road afterwards reverts to a dual carriageway with access to the A22, which provides links to Eastbourne and Hailsham. The road then once again becomes a single carriageway near Pevensey, where the road ends, and the South Coast Trunk Road transfers over to the A259; this coast road starts in Emsworth and shadows the route of the A27.

The road formerly went through Wansford, further to the south. The £250,000 dual-carriageway Wansford North Bypass opened in January 1965. There is a right-turn for Sutton. It is crossed by the Roman road Ermine Street. The dual-carriageway £9 million Ailsworth-Castor Bypass opened in September 1991. Around Peterborough, the Peterborough Longthorpe Grade separated junction (GSJ) opened in December 1987 where it meets the A1260.

Derby Highway is a highway linking Great Northern Highway in Western Australia with the town of Derby. It is a 42 km long 2-lane single carriageway. In the town of Derby, its name changes to Loch Street, where it becomes a 2-lane divided carriageway. The RAAF Curtin inactive air force base is situated adjacent to Derby Highway near the intersection of Great Northern Highway.

It approaches a freeflow junction with the A898 from Erskine Bridge and becomes a high quality dual carriageway route through Dumbarton before running to the west of Alexandria and Bonhill on a bypass constructed in the late 1960s. This dual carriageway ends at the Balloch Roundabout near the western shore of Loch Lomond, where the road enters the Loch Lomond and The Trossachs National Park.

Current plans are to substantially replace the existing N20 with a motorway (the M20). Based on the combined lengths of existing roads, current construction and proposed future construction, it is probable that over 50% of the national primary road network will be either motorway, high-quality dual carriageway or 2+2 dual-carriageway by 2030. Approximately 38.5% (1,105 km) of the network may be motorway.

Bundesstraße 178 (B178) is a German federal highway in the east of the Saxony. It was built as a dual carriageway, and the highway connects with the motorway A4 near the city of Weißenberg in Saxony. It ends in Zittau to the Polish border. After crossing the Polish border, the road reaches the Czech border after a few kilometres, where the Czech dual-carriageway R35 begins.

Low-speed/non-restricted-access roads, known as Autopistas or Carreteras, comprise the majority of the road corridors. Autopistas are divided highways with four or more lanes. Most of these autopistas are single-carriageway roads converted into dual carriageway by building an adjacent road body next to the existing one. Carretera are free, and in most cases, two-lane highways that connect almost all of Mexico.

Seville has one ring road, the SE-30, which connects with the dual carriageway of the south, the A-4, that directly communicates the city with Cádiz, Cordoba and Madrid. Also there is another dual carriageway, the A-92, linking the city with Osuna, Antequera, Granada, Guadix and Almeria. The A-49 links Seville with Huelva and the Algarve in the south of Portugal.

As of 27 July 2010, the N18 commences at the Rosbrien interchange, a major interchange south of Limerick city, where it joins the M7 motorway to Dublin and M20 motorway towards Cork and Tralee. The dual carriageway continues north, intersecting with the N69 road, before crossing under the River Shannon using the Limerick Tunnel, this section of the route forms phase II of the Limerick Southern Ring Road. North of the River Shannon the N18 continues as dual-carriageway bypassing Cratloe, Sixmilebridge and Bunratty. The road passed alongside Bunratty Castle before the completion of the neighbouring dual-carriageway section in the late 1980s/early 1990s.

Towards the end of the 19th century New Park was renamed Pettypool Park and after World War I it became Sandiway Golf Course. Other than the tower, the lodge buildings were demolished when the main road was converted into a four-lane dual carriageway in the 1930s, the tower becoming stranded in the central reservation when the southern end of the Northwich by-pass was completed in 1958. The old road was retained as the eastbound carriageway and the westbound carriageway was added to the south of the tower. It was owned by the Highways Agency who carried out repairs which were completed in 2002.

During upgrading of the Pan Borneo Highway, Lebuhraya Borneo Utara Sdn Bhd (LBU) wants to change the bridge from two-lane carriageway to four-lane carriageway on 2015. The phase 2 of the Durin Bridge will be built under the Pan Borneo Highway project and after its completion, it will turned into a four-lane carriageway bridge. Construction is led by LBU as a turnkey contractor and was taken by HSL DMIA JV Sdn Bhd as the main contractor. It is one of the part of Work Package Contract (WPC 08) which connects Bintangor Junction to Sungai Kua Bridge, including Durin Bridge, Julau Interchange and Sibu Airport Interchange.

The restriction applies from the centre of the carriageway to the back of the footway. Loading and unloading is allowed on double yellow lines at any time, unless there are additional markings indicating that there are 'loading restrictions'. A single short yellow stripe at regular intervals across the kerb or edge of the carriageway indicates that loading and unloading is not permitted at the times shown on accompanying black and white sign plates. Two short yellow stripes at regular intervals across the kerb or edge of the carriageway indicate that loading and unloading is not permitted at any time (and the sign plates may be omitted).

Looking towards the M6 at junction 15 on the original A5006 section The road is the primary access route for traffic to and from almost all areas of Stoke-on-Trent. Starting to the east of Nantwich on the Nantwich bypass the dual carriageway Shavington bypass running north of Hough and Shavington. Returning to the 1980s single carriageway extension route it continues east through a cutting to the M6 at Junction 16 where it becomes a dual carriageway. Continuing through open countryside it passes under the A34 at Talke Pits, turns south before meeting the Tunstall Western Bypass and enters the north of Stoke-on-Trent.

Only the inner west carriageway is reversible, with the inner east carriageway feeding the tunnel southbound. All carriageways were widened by utilising the breakdown lane space, and remarking the existing lanes. After the North Sydney northbound onramp, there are 16 lanes across the whole corridor for a short distance, becoming 10 lanes before the Brook Street exit, and then 6 after the Willoughby road exit. This feeds onto the Gore Hill freeway, completed in 1992. The arrangement is now mostly 4x3x3x3 through the section with the switchable carriageway, with variations in the width of the outer carriageways as ramps enter and exit the freeway.

It resumes as a dual carriageway as it climbs into the retail suburb of Rosebank and leafy Parktown North before dropping down into Dunkeld West as a single carriageway. A short while later it resumes as a dual carriageway and passes through Hyde Park where at a major intersection close to the Hyde Park Corner shopping centre, the road splits north-west when it intersects the start of the M81 William Nicol Drive. It passes through Craighall and Craighall Park crossing the Braamfontein Spruit. It then enters the old Randburg suburbs of Blairgowrie and Bordeaux intersecting Bram Fischer Drive, Ferndale and where the M27 Jan Smuts Avenue ends.

A single carriageway road (North American English: undivided highway) has one carriageway with 1, 2 or more lanes together with any associated footways (North American English: sidewalk) and road verges (North American English: tree belt). A dual carriageway road (North American English: divided highway) has two roadways separated by a central reservation (North American English: median). A local-express lane system (also called collector-express or collector-distributor) has more than two roadways, typically two sets of 'local lanes' or 'collector lanes' and also two sets of 'express lanes'. "Cars only" lanes may be physically separated from those open to mixed traffic including trucks and buses.

The A35 is a main route along England's south coast, and is congested. To help solve the congestion, sections of the A35 were upgraded between Honiton and Bere Regis. Some improvements have involved the construction of new dual carriageway bypasses such as the Puddletown bypass which opened in 1999, and others include new sections of single carriageway road, such as its straightening between Slepe and the Upton bypass in 2004, and the extension of the limit west of Slepe by in 2007. The Puddletown dual carriageway (together with the A30 Honiton-Exeter dualling) were financed under a Design, Build, Finance and Operate (DBFO) contract running from 1996-2026.

The north-south portion from Marangaroo Drive to Widgee Road was historically called Uganda Road and was barely more than a track, but was renamed when the dual carriageway was built in the late 1970s. The name change was made official in March 1979. The road was duplicated from Beach Road to the location of what is now the present-day Hepburn Avenue during the early 1990s, also during the time Reid Highway linked Alexander Drive to Malaga Drive; this was subsequently extended west from there. In 2006, the original single carriageway northbound from Hepburn Ave was upgraded to a dual carriageway to Gnangara Road, where State Route 56 ends.

The A727 road links East Kilbride and the M77 motorway northbound. It runs from junction 3 of the M77 in Darnley to the roundabout on the western edge of East Kilbride connecting the A726, otherwise known as the 'Queensway', and Stewartfield Way and Redwood Drive. Leaving East Kilbride, the road passes through Busby, Clarkston, Giffnock, Thornliebank, Jenny Lind and Arden. It is split between dual and single carriageway, with a section from Peel Road/B766 junction to Spiersbridge Roundabout section being single carriageway, as it passes through the village of Busby, and the towns of Clarkston and Giffnock (excluding the main street of Clarkston, which is a very short dual carriageway).

The southern sections, where there was no need to bypass the existing route, were not originally upgraded to motorway standard, but to dual carriageway without hard shoulders or full grade separation. The gradual construction of the M6 from Rugby (where it met the M1 to London) to Carlisle in 1970, where it terminated on the A74, meant that the route from Glasgow to London was entirely dual carriageway. This led to calls for the already dualled A74 from Draffan to the M6 to be upgraded a second time, to motorway standard. As the government had already invested in the dual carriageway upgrade, they initially resisted these calls.

From Gdańsk to Piotrków Trybunalski, the road has a motorway standard and is marked as A1 motorway. From Piotrków Trybunalski to Katowice, it is part of the Gierkówka route - a dual carriageway road constructed in the 1970s not up to motorway standard, marked as National road 1. As of 2019, the reconstruction of its northern half (from Tuszyn to Częstochowa) into A1 motorway has started, forcing closure of one carriageway and diverting the whole traffic to the second carriageway for the time of reconstruction. From Podwarpie near Katowice to Zwardoń the road partially has an expressway standard marked as S1 (the other parts are marked as National road 1).

Work began in May 2018 on this scheme managed by Highways England and in September 2018 they revealed in a Freedom of Information request that "£30m has been allocated to cover the design, build and initial operation of the scheme for up to six months."Guardian: "Brexit lorry scheme would leave Kent in chaos for weeks". The works included strengthening the carriageways of the M26 and altering the carriageway of the M20 between Junctions 8 & 9\. On the westbound carriageway of the M20, the hard shoulder was converted to a running lane, giving that carriageway a total of four lanes, all remarked with white lines.

Sections of SMA were laid in 1991 and 1993 as part of a trial into preventing deformation of the road under heavy traffic conditions. In 2003, a new section of dual carriageway was opened between the junction with the A63 and Salt End roundabout (the trunk road section). The Highways Agency approved scheme cost over £40 million and was part of a TPI (Targeted Programme of Improvements) as the A1033 was subject to congestion due to the extra port traffic. The new road was built alongside the existing single carriageway, with it being just to the south, and so became the westbound section of the dual carriageway.

Jalan Serdang, consisting of Jalan Raya 5 and Jalan UPM (Selangor state route B13) is a dual-carriageway state roads in Klang Valley region, Selangor, Malaysia.

The second carriageway from Belgrade to Sremska Mitrovica was completed in 1977, while the section from Sremska Mitrovica to Šid was opened to traffic in 1987.

The viaduct has been incorporated into the A9 motorway route since 1999. Like the Mirna Bridge, as of December 2011, the viaduct comprises a single carriageway.

This section of the road opened as a dual carriageway on 12 December 2014. This completes the dualling of the trunk road between Norwich and London.

There are also seven service areas on the Tangenziale di Napoli of which four are located on the westbound section and 3 on the eastbound carriageway.

The single- carriageway bridge is due to be doubled by 2021, making the Southern Link Road dual between Junction 7 of the M5 and Powick Roundabout.

The majority of the Cunningham Highway is a single carriageway with freeway standard and 6-lane arterial road standard towards its north-eastern terminus, near Ipswich.

The 138 mile (222 km) section between Bridge of Allan and Inverness, via Perth, was substantially rebuilt during the 1970s and 80s, but it follows essentially the same route except where it bypasses towns and villages instead of running through their centres. Between Perth and Inverness, the road has been dubbed Killer A9, because of accidents and fatalities where dual-carriageway sections merge into single-carriageway - the principal cause being motorists driving at excessive speeds to overtake lines of slower-moving vehicles before the dual carriageway ends. Dangerous overtaking manoeuvres on the long single-carriageway stretches of the road are also common causes of accidents, as are the non-grade separated junctions along the northern sections, where drivers make a right turn across the opposing traffic flow. One of the sections of dual carriageway built in the late 1970s/ early 1980s; this is the section in the north of Perthshire between Dalnacardoch and DalnaspidalThe most significant alteration of the A9 route was the realignment of the route north from Inverness, crossing the Moray Firth via the Kessock Bridge, cutting through the Black Isle and back across the Cromarty Firth.

There were proposals to turn the A120 into a dual carriageway between Braintree and the junction with the A12. In July 2009 the proposed improvements were 'scrapped'.

Once this is complete, it will be possible to travel between Melbourne to Brisbane via Sydney on a mix of controlled access and limited access dual carriageway.

The road has kept its principal status in the west from Honiton, Devon to Land's End where it is mainly dual carriageway and retains trunk road status.

The changes include new cycle lanes, various measures to reduce congestion and an improved public realm with new pavements, carriageway resurfacing, community greening schemes and pocket gardens.

No trace of the station now remains, as it was removed when the dual carriageway was built. It was situated where this crosses over the Culcavey Road.

In March 2018, construction started on duplicating the last remaining section of single carriageway road, from Hepburn Avenue to Gnangara Road, which was completed in October 2018.

In 1954, the bridge was extensively reworked to allow for independent use by road, rail and pedestrians. The towers were torn down and the carriageway was enlarged.

Greek National Road 30 (, abbreviated as EO30) is a single carriageway road in central Greece. It connects the cities of Arta and Volos, via Trikala and Karditsa.

In December 1997, the dual-lane Pacific Highway Taree bypass opened and as a result, most of the traffic carried by the Martin Bridge became local traffic. The second carriageway was opened to traffic in April 2000 and became the southbound carriageway of the re-routed Pacific Highway. The Pacific Highway has two bridges that cross the Manning River. The southern bridge is named The Ella Simon Bridge.

However the route continues as Willen Road into Newport Pagnell. The H5 Portway begins its life in Oakhill as a single carriageway and remains as such up until its junction with the A5. From there it becomes a dual carriageway and becomes the A509. It runs along the top edge of Central Milton Keynes, over Willen Lake and terminates at Northfield Roundabout with H6 Childs Way near M1 Junction 14.

The remainder of the roadway from the plantation to the north follows the existing Majura Road alignment, with the addition of a second carriageway constructed to the east. It curves towards the west and joins onto the existing interchange with the Federal Highway. The roadway itself then continues on through the interchange into the Gungahlin district as Horse Park Drive. The parkway is dual carriageway for the entirety of its length.

The A4042 is a trunk road that runs from Abergavenny to Newport in south Wales. Starting at the junction of the A40 and A465 south of Abergavenny, the A4042 travels south towards Little Mill north of Pontypool. This section is a single carriageway and is winding and undulating. From Little Mill onwards the road is dual carriageway, bypassing Pontypool and Cwmbran before crossing the city boundary into Newport.

The Scottish Government has announced plans to upgrade the A96 road to dual carriageway by the year 2030, at a cost of £3 billion. The project includes dualling the 88 miles of the A96 that is not dual carriageway between Aberdeen and Inverness, An 18-mile section of the A96 between Inverness and Auldearn and will bypass Nairn will be the first section of the A96 to be dualled.

Horsham lies at the junction of three main routes with the dual carriageway A24 running north to south route from London and Dorking to Worthing. The A264 links Horsham to Crawley and the M23 to the east by a modern dual carriageway and to the A29 to the west. The A281 runs between Guildford and Brighton. Bus services are provided by Metrobus, Stagecoach South, Arriva Southern Counties and Compass Travel.

Diagram showing different arrangements of the elements of a road thumb A carriageway (British English) or roadway (North American English) consists of a width of road on which a vehicle is not restricted by any physical barriers or separation to move laterally. A carriageway generally consists of a number of traffic lanes together with any associated shoulder, but may be a sole lane in width (for example, a highway offramp).

During the mid-1970s the A38 trunk road was upgraded to a dual carriageway. Station Road, a country lane in the early part of the 20th century, was also widened to become a dual carriageway and form part of the Avon Ring Road. In 1973, the Rolls-Royce car division was separated as Rolls-Royce Motors. Rolls-Royce (1971) Limited (the engine division) was privatised in 1987 as Rolls-Royce plc.

Patchway Trading Estate is adjacent to the dual carriageway linking the A38 and M5. The mall and two retail parks at Cribbs Causeway, just north of Filton airfield, form the largest shopping centre in South West England. On the opposite side of the railway track is the Stoke Lodge housing estate. The A38 trunk road, upgraded to a dual carriageway in the mid-1970s, separates the two housing estates.

At Wincheap, the A28 meets the A2, although only westbound traffic can exit the A2 at this point. The A2050 rejoins the A2 at Bridge. Traffic for the Channel Tunnel and Folkestone leaves at the junction with the A260, and shortly after this junction the A2 loses its dual carriageway status, regains it, and loses it again within a few miles. Now single carriageway, the A2 forms the Dover bypass.

The A64(M) continues east as graded dual carriageway with a mix of grade separated and traffic light controlled junctions. The Inner Ring Road junctions off and heads southwards towards the East Bank. Here, it meets the East Leeds Link Road, which provides fast connections to the M1 northbound. It continues over the River Aire as a high quality dual carriageway on a flyover, meeting the M621 at Junction 4.

Unusually, one service area is provided for both traffic directions and it is all located to the south of the motorway. Access from the eastbound carriageway is via a tunnel underneath the M25. Access from the west-bound carriageway is from the motorway itself. As with a number of modern service stations, many have an ecological aspect such as an sustainable drainage system, rain-harnessing or a renewable energy source.

This timber frame, brick and cement render warehouse with four storeys and basement stands in Charlotte Street. At the north-eastern end of the building a highly differentiated bay marks a carriage entrance. Large pilasters separate six window openings and the carriageway bay. Three of these pilasters mark the ends of the building and the carriageway bay and are distinguished, by greater ornamentation, from the five "minor" pilasters.

The A12 heads to Lea. The section from the Lea Interchange to Leytonstone, also known as the M11 Link road, was built in the 1990s in the face of a major road protest. During this work the old section as far as Wanstead was rebuilt as a dual carriageway. Prior to that, the A12 started at the Green Man Roundabout at Leytonstone, and was single carriageway west of Wanstead Underground station.

The road had a reputation for being dangerous, primarily because the majority of it is single carriageway. Cars therefore have to turn across oncoming traffic to access adjoining roads. Between 1999 and 2005, there was an average of 90 accidents per year . A local campaign group 'Action - Access - A1079' propose that in the long-term, more of the road be made dual carriageway to help combat these problems.

Map of Greater London showing the South Circular Road (green) and the North Circular Road (red) The South Circular is long. The majority of the road is single carriageway, one lane each way, aside from a small section of dual carriageway near the Woolwich Ferry. It is a primary road for its entire length. The route runs closer to central London compared to the more distant North Circular.

In December 2012 it was announced that from Temple to Higher Carblake would be upgraded to a dual carriageway. Building started in early 2015, and was completed in summer 2017. This work made the A30 continuous dual carriageway between the M5 at Exeter and Carland Cross in Cornwall. On 17 January 2008, British Airways Flight 38 crash-landed near the Great South West Road southeast of Heathrow Airport.

The Kingston Bypass continues south-west for another , before passing under Spring Farm Road and curving around to meet Channel Highway and Algona Road at a large roundabout, further south. The bypass is a dual carriageway around the Summerleas Road interchange, and a single carriageway elsewhere. It is the northern section of the B68 road route, which continues south along Channel Highway, and has a posted speed limit of .

At the border with the Republic the A3 meets with the N16 road to Sligo. For its entire length the A4 is a primary route. At present, it is mainly single carriageway, apart from a 13 mile long section from the end of the M1 at Moygashel until Ballygawley, which is dual carriageway. There are numerous stretches of the route which have overtaking lanes through counties Tyrone and Fermanagh.

Traffic and congestion is a regular problem along the A303, particularly near Stonehenge. Since the 1950s, the A303 has been criticised for being inadequate for the level of traffic along it. In 1959, it was reported that a typical queue for holiday traffic along the road could be as much as . In 2017, over of the road west of Amesbury remains single carriageway, interrupted by various sections of dual carriageway.

Iain recognises the address of the injured casualty as Alicia Munroe (Chelsea Halfpenny) and tells Ruby that they need to leave. Ruby is sceptical about leaving Mia, but Iain tells Ruby not to question him. After collecting Alicia, Iain drives her and Ruby down to the emergency department (ED) via the dual carriageway. As Iain is driving, he notices Mia standing on the bridge over the carriageway, preparing to jump.

The airfield site is now occupied by agriculture, a go- kart centre and the realigned A1 dual carriageway, whereas the technical and domestic sites are an industrial estate.

Additionally, it was proposed that the existing A5 could be upgraded to full dual carriageway grade separated standards together with improvements to the A41 and A464 trunk routes.

The RN 9 continues South to Riom and the volcanic region of Auvergne. The road is dual-carriageway for 10 km into the industrial city of Clermont-Ferrand.

From here to Bassets Pole, the route is single carriageway, running alongside the M6 Toll. The road terminates at the Bassets Pole roundabout, meeting the A38 and A453.

In 2009, the A830 "Road to the Isles" and A851 on the Isle of Skye have had their single-track sections replaced with higher-quality single-carriageway road.

The width of the road is making it four-lane to most of the stretch while few km near the western end is wider to six-lane carriageway.

There are no intermediate exits on the southbound carriageway of Tsing Long Highway on the north of Tai Lam Tunnel, so this entire section is a toll road.

The highway is an all-weather tarmac single carriageway road. It offers the most direct route from Kampala to the oil-rich Albertine region in the Western Region.

The A6177 is a ring road around Bradford in West Yorkshire, England. It is mostly formed from existing roads and save for its southern section is single- carriageway.

From Cambewarra Road the highway is four lane divided through Bomaderry and to near the junction with Warra Warra Road in South Nowra. Duplication to dual carriageway standard of a length south from here to Forest Road was scheduled for completion in early 2014, following a three-month cessation of work while measures were put in place to protect a hitherto unknown area of habitat of the endangered green and golden bell frog. Beyond this section is of four lane single carriageway from Forest Road to the junction with Jervis Bay Road. From Jervis Bay Road southward the highway is mostly single two lane carriageway along the NSW South Coast, passing through Ulladulla, Batemans Bay (where the town centre bypass is built as dual carriageway), Moruya, Narooma, then bypassing Bega and Merimbula and passing through Eden, before crossing the border at the Black- Allen Line into Victoria, from Sydney and from Melbourne.

There is also a variant of the inverted SPUI which can be used when a side road ends at, rather than crossing, a free- flowing road. In this variant, one carriageway of the free-flowing road is grade-separated from the side road, as with a typical inverted SPUI; while the other carriageway of the free-flowing road is at-grade with, but still separated from the side road, as found in a continuous green T- (or seagull) intersection. There is one such interchange in Pultney Township, Belmont County, Ohio, between and Interstate 470, at . The ramps leading to and from I-470 run west of, but are not directly connected to SR 7; these ramps form the "side road" at this interchange. The southbound carriageway of SR 7 bridges over the interchange, while its northbound carriageway remains at- grade. SR 7's left run between its carriageways, meeting the I-470 ramps at an at-grade intersection.

On the southern flank of the Zirler Berg lies the only hairpin on the Zirlerbergstraße – by the Gasthaus Zirlerberg Rast at about 818 m – where there are views of the Inn valley. Between Zirl and Leithen the northern carriageway of the Seefelder Straße (the uphill carriageway) is closed to caravans with a permitted total weight of over 750 kg and the whole of the road between Zirl and Scharnitz is barred for lorries over 7.5 tonnes with the exception of local lorry traffic. Due to the steep gradient there are several escape lanes between Leithen and Zirl that branch off the downhill carriageway; they runn slightly uphill so that in an emergency, vehicles, especially lorries, can be braked by the gravel roadbed. The gradient also means that bicycles are not permitted on the downhill carriageway; although they are allowed to climb the road, this is not recommended due to the high levels of traffic.

The Humber Bridge connecting North Lincolnshire to the East Riding of Yorkshire Being on the economic periphery of England, Lincolnshire's transport links are poorly developed compared with many other parts of the United Kingdom. The road network in the county is dominated by single carriageway A roads and local roads (B roads) as opposed to motorways and dual carriageways – the administrative county of Lincolnshire is one of the few UK counties without a motorway, and until several years ago, it was said that there was only about of dual carriageway in the whole of Lincolnshire. The M180 motorway passes through North Lincolnshire, splitting into two dual carriageway trunk roads to the Humber Bridge and Grimsby, and the A46 is now dual carriageway between Newark-on-Trent and Lincoln. The low population density of the county means that the number of railway stations and train services is very low considering the county's large area.

The 1989 re-alignment of the Princes Highway (along La Trobe Terrace) provides a dual carriageway, four-lane limited access road to replace the original route along Moorabool Street in South Geelong and High Street in Belmont. Upon the completion of the final section of the Geelong Ring Road, another section of the Princes Highway was superseded in 2013 at Waurn Ponds. After Geelong the highway heads in a generally western direction, continuing with the 'M1' designation as a dual carriageway road to Winchelsea (opened 2015). West of Winchelsea, the road is presently is being reconstructed to dual carriageway standard, passing through Colac, before reaching Camperdown - ultimately reaching the port of Warrnambool.

North of the interchange, US 29 intersects several major routes that serve the town of Columbia: Shaker Drive/Seneca Drive, Broken Land Parkway, MD 175, and MD 108. Between Broken Land Parkway and MD 175, US 29 has a right-in/right-out interchange between the southbound carriageway and South Entrance Road; the northbound carriageway has two at-grade direct turnoffs to Gates Lane and Old Columbia Road, with median crossovers provided for southbound traffic. Near the MD 108 interchange the northbound carriageway has another direct turnoff to Diamondback Drive. Beyond the MD 108 interchange, US 29 upgrades again into a fully limited-access six-lane grade-separated freeway as it encounters the western terminus of MD 100.

The A12 starts just north of the Blackwall Tunnel at a junction with the A102 and the A13. From here to past Ipswich (including the entire section through London) the road is a dual carriageway. North of the junction, the A12 heads northwards as a 2/3 lane dual carriageway mostly at street level. This stretch of road is known as the Blackwall Tunnel Northern Approach. This stretch ends at the triple-layer interchange with the A11 at Bow Road where it becomes the East Cross Route. This is mainly a 3/4 lane dual carriageway built mainly on flyovers and underpasses and was built in the late 1960s, previously called the A102(M).

Prior to the opening of this new dual-carriageway route in 2004, the route ran along a two-lane road through Shannon town centre itself. A junction without flyovers connected to what was then the end of the dual- carriageway section of the N18 (the dual-carriageway on that route now continues to Galway as a motorway as of September 2017). Shannon Town can still be accessed from the N18 by use of the remaining portions of this road (connecting only as a slip road from the Limerick direction), as well as a new local link road from a new interchange at Hurler's Cross. The N19 no longer serves Shannon Town for most purposes, apart from the industrial estate.

The Ashburton bypass, much like the Kennford bypass, uses the alignment of a much older 1930s single carriageway bypass, which was subsequently upgraded to dual carriageway by 1974. At the town of Buckfastleigh, the route once again bypasses on a new alignment, although due to the challenging topography of the area, the road crosses part of the town on a viaduct. The road occupies part of the alignment of the former Totnes to Ashburton railway line. From Buckfastleigh to the A385 junction, the current road follows the route of original single carriageway, with the majority of this section being upgraded between 1973 and 1974, although a small section at Dean Prior was upgraded between 1966 and 1967.

Immediately north of the settlement, Carland Cross traffic roundabout is the junction of the A39 and the A30 trunk road. To the east of the roundabout, the A30 is a dual carriageway road: to the west the A30 is single carriageway and to the south the A39 is also single carriageway.Ordnance Survey, 1:25000 'Explorer' map, sheet 106, There is motorists' services area, including a filling station, by the roundabout. Proposals to create a new dual carriageway between Chiverton Cross and Carland Cross will see a transformation of the Carland Cross roundabout with the existing roundabout retained, but connected to an additional roundabout to the north forming a dumbbell style grade separated junction with the A30 realigned.

The services are located between junctions 16 and 17 of the M6 on both sides of the carriageway. The nearest town is Sandbach. Nearby attractions include Jodrell Bank Observatory.

The remainder of the road through Newton Mearns has been converted into a two- lane dual carriageway with cycle lanes. The cycle lanes end at Eastwood Toll in Giffnock.

Jalan Kampung Bandar Dalam, Federal Route 2 is a single carriageway federal road in Kuala Lumpur, Malaysia. It is a hidden route to Kuantan via Kuala Lumpur–Karak Highway.

The original main street going into Bentong town has been modified to a dual carriageway. It is bordered by Selangor on the west and Negeri Sembilan on the south.

Northbound carriageway just before exit 313. Tanjung Kupang checkpoint. The Kilometre Zero for the entire expressway is located at the Malaysia–Singapore border at the Malaysia–Singapore Second Link.

Pedestrians were also unable to use the bridge because of the narrow width of the carriageway."New Gwynedd Bridge Shortens Path by 10 Miles!" walescoastpath.gov.uk, Retrieved: 6 June 2018.

Trains operated frequently to Central and Queen Street stations. By road, the stadium was also served by the A4232 dual carriageway, which is approximately away from the Leckwith Interchange.

First Truck Check Station in Operation Truck & Bus Transportation February 1959 page 61 In 1986, the town was bypassed when a dual carriageway section of the Hume Highway opened.

Reconstruction of the road began on 6 September 2012 to convert the road to a dual carriageway. Construction was scheduled for completion in 2014, but has been on hold .

Buiten Street, Welkom Welkom is connected to Kroonstad and the N1 north via the R34, a dual carriageway. Alternatively if driving south to Bloemfontein via the R30 through Brandfort.

On 28 May 2010, the motorway was completed and had replaced almost all of the single-carriageway N8 except for a short section of urban road in Cork City.

The second phase (19 km in length) from Carrowntrella-Bohola was planned to be of type two dual-carriageway standard and would have bypassed Foxford and Swinford. It would also have been the first dual carriageway ever constructed in Co Mayo and was to join the N5 just west of Bohola. However, planning permission for the project was denied by An Bord Pleanala in 2010 and the road is now being redesigned.

Standard motorways: 52,000 vehicles AADT - annual average daily traffic. The road type is all-purpose dual carriageway (D2AP), but with the same specifications as motorway: a carriageway width of 7 metres (23 ft) and a hard shoulder of 2.5 metres (8 ft 2 in) width. HQDCs are limited access (grade-separated junctions only) and not intended to have junctions with minor roads. Junctions with major roads are grade-separated and to motorway standards.

Travellers by car from Sialkot reach the airport by travelling west on the Sialkot-Wazirabad Dual Carriageway, turning right at Sambrial to Airport Road and then go straight for 5 km to reach the airport. From Gujranwala, take Sialkot Road up to Daska and then go to Sambrial Road. After reaching Sambrial turn right and go straight on the Sialkot-Wazirabad Dual Carriageway. After crossing the Sialkot Dry Port turn left on the Airport road.

The construction began in June 2003, and was commissioned in July 2007. The construction of the carriageway was split into two parts; northern and southern sections. Gammon Construction (at that time incorporated as "Gammon Skanska Limited", partially named after Skanska, a co-owner of the company) was the principal contractor for the northern section, and built around of the carriageway. China State Construction joint venture was in charge of the southern section.

Leidschendam-Voorburg is connected to the A4 (Amsterdam - Belgian border by Rotterdam) and A12 (The Hague - German border by Utrecht) motorways, which cross each other near the city center of Voorburg. The N14 dual carriageway, which connects the A4 at Leidschendam to the N44 dual carriageway at Wassenaar runs through a series of tunnels in the municipality. Together with a part of motorway A4 and several local roads the N14 forms the Ring Den Haag.

Further west on St Neots Road a cafe, a beauty salon, a pet shop, a car repair/maintenance garage, an agricultural machinery merchant and a furniture store can be found. right In 2006 to 2007 the A428 was improved with a new section of dual carriageway, replacing the section of single carriageway, past Cambourne to Caxton Gibbet. Around the same time the postcode was changed from CB3 to CB23 for this sector.

The A660 starts in Leeds city centre, officially at the junction of Woodhouse Lane and Claypit Lane. The northbound carriageway passes Leeds Metropolitan University's "civic quarter" campus, crosses the A58(M) (Leeds Inner Ring Road), which is in a cutting, and passes the University of Leeds with its landmark tower. The southbound carriageway is separated, at one stage by several terraced streets. The carriageways combine before crossing Woodhouse Moor to Hyde Park.

Just before the Kildwick level crossing, the road takes a bypass around Eastburn and Steeton on a dual carriageway that was opened in 1989. At Keighley, the A629 diverts through the town whilst Aire Valley traffic takes the A650. Through and beyond Keighley to Halifax, the road is a single carriageway. After going through Keighley town centre, the road heads due south but up onto the high ground through Ingrow, Cross Roads and Denholme.

The A256 was outlined as a strategic corridor by Kent County Council in 1999. At a board meeting the following year, two proposals ("East Kent Access" phases 1 and 2) were announced. The first phase, implemented between 2003 and 2005, contained various junction improvements and upgrading single carriageway sections around Sandwich to dual carriageway. Phase 2 was a major upgrade of the approach to Thanet and the largest highway project constructed by the council.

It passes a BP garage on the left, with the Leeds-Wakefield Holiday Inn on Queen's Drive, and the Silkwood ParkSilkwood Park business park and the Days Hotel Wakefield on the right. It meets the M1 at a roundabout and continues to the west as a dual-carriageway, passing through Gawthorpe. The former A638 continues through Ossett as the B6129. It becomes the single-carriageway Chancery Road at a roundabout with Leeds Road (B6128).

National road network Total length (including European routes and Highways) of National Roads in 2019 is 17,873 km (11105.77 mi), an increase from 17,272 km (10,732 mi) in 2015. The majority of National Roads (DN) are single carriageway, with only 12.5% being dual carriageway. A major problem being that many National Roads (drumuri naționale) have no ring roads around cities and towns, disrupting the traffic flow (i.e making traffic condition more difficult).

The road begins (at its southern end) north-west of junction 36 of the M6 motorway at Brettargh Holt roundabout with the A590 road close to Sizergh Castle. It bypasses the town of Kendal as a dual carriageway, this £1.9m section opened on 29 August 1971. It becomes a busy single carriageway road as it enters the Lake District. It bypasses the town of Windermere, closely following the north-eastern bank of Windermere.

The street is crossed by the Weesperplein to the north, a dual carriageway section of the Weesperstraat, and to the south side by the Rhijnspoorplein a dual carriageway section of Wibautstraat. At Roetersstraat there is a building complex known as Roeterseiland at the Sarphatistraat campus of the University of Amsterdam. At the Alexanderplein the Sarphatistraat intersects with the Plantage Middenlaan. From 2009 to 2012, the Theater Instituut Nederland (TIN) was located at Sarphatistraat 53.

The Carriageway is believed to have been built , during Albury's boom period. It is a mid-Victorian residential building consisting of a pair of substantial two-storey town- houses of brick construction and terrace form with a central carriageway. It is one of the oldest mid-Victorian residential buildings remaining in Albury and it is an unusual and elaborate example of its type. Its architectural form and detail is distinctive and inventive.

When the B1230 was the A63, a three-mile section, through Gilberdyke and Newport, was dual carriageway. Where the B1230 crosses the M62 motorway east of Newport, the M62 finishes and the A63 restarts. Before the last eastern section of the M62 was built, the motorway terminated at a temporary junction at Balkholme. Before the M62 opened, the single carriageway A63 was Hull's main route to the South of England, causing many bottlenecks.

The original route between Leeds and Wetherby has a dual carriageway diverting from Roundhay Road/Wetherby Road, at the old Fforde Grene junction in Harehills. It runs along the Easterly Road dual carriageway passing Oakwood and Gipton. The re-routed A58 meets its original route at Boggart Hill in Seacroft. The re- routed section was constructed in the 1930s and had a branch of the Leeds Tramway running along the central reservation until the 1950s.

Beginning in 2012, a major upgrade project costing £133m was undertaken to upgrade the remaining single carriageway section between Coleman's Corner and Larne to High-quality dual carriageway and replace all major junctions with grade separated overbridges or LILO junctions to improve safety on a previously very dangerous road. In addition, the village of Ballynure, for many years a major bottleneck on the route, was bypassed as part of the part the scheme.

Drumpellier Drive is a four lane dual carriageway south of Gnangara Road, and a two lane single carriageway north of Gnangara Road. It has a speed limit of south of Marshall Road, and a speed limit of north of Marshall Road. Drumpellier Drive starts off at an intersection with Reid Highway, as a continuation of Daviot Road. From there, the road heads north, between the developing suburbs of Bennett Springs and Dayton.

Bedford lies on the A6 road, and two of the most important north- south routes in Great Britain, the A1 and the M1 motorway pass a few miles to the east and west respectively. The A421 link the town to the M1 and A1 via dual carriageway. This will significantly improve access to the town, which currently requires the use of frequently congested single carriageway roads. Bedford has a southern bypass along the A421.

A Pothole on the N15 near Castelgal school The route between Lifford and Stranorlar is a single carriageway road of very poor quality. A replacement of the current alignment with a new single carriageway road is planned, bypassing Castlefin, Liscooley, and Killygordon. This will connect with a 2+1 bypass of Stranorlar and Ballybofey which is also planned. This will bypass the towns to the south, with a new crossing of the River Finn.

The A92 passes north/south through the town and connects Glenrothes with Dundee in the north and Dunfermline in the southwest where it merges with the M90. This gives Glenrothes a continuous dual-carriageway link to Edinburgh and the major central Scotland road networks, whilst much of the route north to Dundee remains a single-carriageway. Local campaigners have for a number of years sought the upgrade of the A92 north of Glenrothes.

The length of the A6 in Latvian territory is . Currently the A6 has two lanes in each direction between Riga and Ogre and between Nīcgale and Daugavpils, with other parts having just a single carriageway. The current speed limit in winter is , but in summer the dual carriageway parts are raised to . Since 2013 a shorter route has replaced the Salaspils-Koknese section of A6 (numbered as P80), mainly built for transit traffic.

From Kyiv to Lviv the M06 is part of European route E40, European route E471 from Lviv to Mukacheve, European route E50 from Stryi (Lviv Region) to Uzhhorod, and European route E573 from Uzhhorod to the Hungarian border. From Kyiv to Rivne, the road features 2 lanes in both directions with physical separation, with the exception of Zhytomyr bypass. From Rivne on, the road is mostly a single carriageway, though some dual carriageway sections exist.

The road resumes its original route on the West side of Halesowen, entering Worcestershire and passing over the Clent Hills. The A491 is crossed in the village of Hagley, where the road becomes single carriageway once more, passing through the village, closely followed by the village of Blakedown. Beyond there a dual carriageway section takes the road to Kidderminster, crossing the A449, before following the town's Ring Road to the North side.

Worksop bypass The £11.3 million Worksop Southern Bypass opened in May 1986. It starts at the roundabout with the B6041 (for Gateford and the former route through Worksop). The next short section is dual-carriageway to the Shireoaks roundabout, which also has access to the Gateford and Dukeries industrial estates. It becomes single-carriageway and crosses the Sheffield to Lincoln Line, at the junction with the Robin Hood Line, and over the Chesterfield Canal.

The A38 passes Endsleigh Garden Centre, which used to have direct access from the dual carriageway, although since the early 2000s this has been closed and the garden centre is accessed from the Westover junction for Ivybridge. After Ivybridge, the route roughly parallels the original route, bypassing the village of Lee Mill which is now home to a large trading estate. The road widens to a three-lane dual carriageway for the Plympton bypass.

The announcement then said that the road from Morpeth to Ellingham would be upgraded to dual carriageway. The selection of the preferred route was scheduled for the year 2017, with construction due to begin in 2019. In response to questions regarding transport in the north, Highways England stated that a new dual carriageway section between Morpeth and Fenton and also that of Alnwick to Ellingham would start in 2012 with full opening in 2023.

It continues via Morehampton Road and Donnybrook Road, through Donnybrook, with the route becoming dual carriageway at Donnybrook Church, which marks the beginning of the Stillorgan Road. The Stillorgan Road brings the road past Belfield, where University College Dublin is located (and accessed from a grade-separated interchange on the dual carriageway - the first full interchange built in Ireland) and onwards to its junction with the N11 and N31 at Mount Merrion Avenue.

The route of the A6 in red from Derry city to Belfast (Co. Antrim). The A6 road in Northern Ireland runs for 71.4 miles (114.9km) from Belfast to Derry, via County Antrim and County Londonderry. From Belfast to Randalstown the route has been superseded by a motorway (the M2 and M22). Mostly single carriageway, there are sections of dual carriageway in Antrim town centre and from Randalstown to Toome, including the Toome bypass.

1895 photograph, has also been replaced. However, the design and construction of the new fence replicates the original fencing, as closely as possible, and retains the original gates and piers. The paths and carriageway (currently a driveway) are maintained with locally sourced, finely graded washed river gravel as per the original paths and carriageway. Within the grounds there is archaeological potential for the footings and under-floor deposit of the Summer House.

However, in 1995, the stretch between the traffic lights junction at Teluk Intan town center to the traffic lights junction to Federal Route 109 was upgraded into a four-lane, dual carriageway road. In 2004, the stretch between Federal Route 109 to Selabak Estate was also upgraded into a four- lane, dual carriageway, as was the stretch between the traffic lights junction to Jalan Kampung Banjar and the traffic lights junction at Federal Route 5.

Starting at junction 4 of the M5, the road heads West on a single carriageway alignment, meeting the B4091 at a roundabout, then becoming a dual carriageway. There are local accesses for the villages of Belbroughton, Clent, Romsley and Holy Cross. Following a roundabout in Hagley the A491 is concurrent with the A456 for a short period before heading north towards Stourbridge. At Pedmore the A4036 leaves at a roundabout towards Dudley.

The N73 road is a national secondary road in Ireland. It is made up entirely of single carriageway with few overtaking opportunities and only a small amount of hard shoulder.

The New Dover Road, B2011, that runs between Folkestone and Dover, is the main carriageway. The nearby A20 used by freight and ferry traffic heading for the port of Dover.

Thereafter, the route to Durban is dual carriageway motorway. This last section is the second longest motorway by route number, but the longest motorway following one alignment in South Africa.

The buses were diverted, the dual carriageway was removed, forecourts and railings were restored, and Queen Square re-emerged as a magnificent public space surrounded by high quality commercial accommodation.

The first proposals were for an inner ring road that would be a dual carriageway. This met opposition as it would call for demolition of homes and many archaeological sites.

The connecting line itself has some of the attributes of a tramway, running in the carriageway of a road during its crossing of the Danube on the so-called Eisenbahnbrücke.

Approx annual tonnage: 800,000. Connections to major transport links - A17, A47 east coast to A1/M1 carriageway. The port runs a fortnightly service from Riga, Latvia importing from the Baltic.

The speed limit begins at 60 km/h, increasing to 70 km/h at the dual carriageway. Direct access to the Nowergup Rail Depot is also provided by the road.

The A5268 is Chester's Inner Ring Road. The road, which was built to dual carriageway standard, has roundabouts and traffic lights. Its purpose was to enable the pedestrianisation of Chester.

The N20 dual carriageway between Pamiers, Foix and Tarascon-sur-Ariège is to be upgraded to motorway standard, and renumbered the A66, however no date for this has been announced.

Eight larger specimens could be preserved and transplanted. Young trees are replanted on both sides of the carriageway so that an avenue is created on large parts of the Löwentorstraße.

The Church Village bypass, as it is known, has been built as a single carriageway, with crawler and overtaking lanes around roundabouts, and was opened for traffic in September 2010.

The cross section of the bridge comprises two dilated structures, each carrying one motorway carriageway consisting of two wide traffic lanes and one wide emergency lane. The bridge is wide overall.

Jasin–NSE Highway (Malacca State route M25) is a dual-carriageway highway in Malacca State, Malaysia. It is also a main route to North–South Expressway Southern Route via Jasin Interchange.

Major upgrades to the road were completed in December 2009 completing the first intercity motorway/dual carriageway in Ireland and the New Junctions of M6 are built and will be 164km.

It crosses the A63 and meets a roundabout with A164 (for Beverley) and A1105, then turns left along a short section of dual-carriageway (former A63) to end at the A63.

It forms the main thoroughfare in Carnoustie and turns north at the eastern end of the town, heading north towards Muirdrum. The road is a single carriageway along its entire length.

In the 1970s the junction was upgraded and the tree removed. In 2004 the 1960s road was replaced with a new dual carriageway and the junction was replaced with an overbridge.

On 1 December 2013 a driver was killed in a car crash which closed the road for three hours. The car "left the carriageway" after travelling from St Athan towards Cowbridge.

Cyclopark is a purpose-built facility for cycling and other outdoor activities, located on the south side of Gravesend, north Kent in south-east England, adjacent to the A2 dual carriageway.

The Dalton vault was erected in the first Roman Catholic Section. In 1904 the Trustees were informed by the Department of Lands of the discontinuation of government subsidies for general maintenance and improvements. In 1906 the Trustees produced "Regulations for the Management of the Portions of the General Cemetery at Gore Hill" and in 1908 the portion of the Cemetery east of the Carriageway was revoked and re-dedicated for General Cemetery. In 1910 Mr Kennedy was succeeded as Sexton by Frederick Crowe. In 1917 east of the Carriageway, the Roman Catholic and Unsectarian areas were redesigned and the Jewish Area eliminated and in 1919 east of the Carriageway the Methodist and Presbyterian burial areas were redesigned to increase the Presbyterian area.

Bypassing the Royal Glamorgan Hospital, Avionics department of British Airways and the Headquarters of the Welsh Blood Service. On the south-bound carriageway is a long stretch of original road, although now a parking area where refreshment vans and sleepy truckers are a common sight, it provides access to some houses and a rural lane leading to Llantrisant. The Road then comes to a roundabout with a turn off for the Llantrisant Industrial Park which is home to the Royal Mint. Another smaller roundabout at the village of Ynysmaerdy, where the new Headquarters of the South Wales Fire and Rescue Service is located, marks the end of the Dual Carriageway, the road becomes a single carriageway again at this point.

The main characteristic of this dual-carriageway, heavily-landscaped bypass is that it was obviously built in anticipation of a similar (dual-carriageway) bypass of Mansfield, which although planned, never arose, and was built as single carriageway instead. There is an exit to the north with traffic lights for a coal disposal point. The Rainworth bypass crosses Clipstone Forest and Rainworth Water, enters Mansfield District, and meets the former route of the A617 at the large landscaped Three Thorn Roundabout (named after Three Thorn Hollow Farm), built in anticipation of a bridge over the roundabout at the junction. The £8m Rainworth Bypass, built by Birse, was opened on Friday 23 June 2000 at 1.30pm with a commemorative plaque unveiled on the trussed footbridge to Strawberry Hill.

At Proefplaas Interchange with the N1, the N4 now follows the N1 North, as part of the Platinum Highway (Co- signed), to just north of Zambezi Drive (R513, now named Sefako Makgatho Drive) where it splits off westward towards Rustenburg just before the Pumulani Toll Plaza on the N1 (the N4 is still called the Platinum Highway after this interchange). The N4 now bypasses Pretoria through the east and the north as a four-lane dual-carriageway motorway. After Rosslyn, the N4 becomes a single carriageway highway, and joins the old R27 alignment at the R512 road to Brits. Three new grade-separated junctions were built before Rustenburg, as well as a new single-carriageway bypass of Rustenburg to the south of the town.

Albany Highway as a dual carriageway in Cannington The two roads converge at an intersection with Welshpool Road, and for Albany Highway serves as an arterial route in Perth's south-eastern suburbs, varying between a single carriageway and dual carriageway, and between a four- and six-lane capacity. This part of the highway is dominated by commercial shopping precincts in Bentley, Cannington, Maddington, Gosnells and Kelmscott, with numerous sets of traffic lights. The section of Albany Highway through Beckenham and Kenwick is allocated Alternate State Route 30, while State Route 30 follows a bypass, Kenwick Link. Albany Highway has a folded diamond interchange with Tonkin Highway in Gosnells, and continues south for past commercial and residential properties in Kelmscott and Mount Nasura.

Now within the suburb of Nowergup, the road reduces a two- lane single carriageway 2.6 km (1.6 mi) north of that intersection, which continues as such until Trian Road in Carabooda, where a four-lane single carriageway reappears and continues as such for 3 km (1.9 mi) until Bernard Road South, reducing to a single carriageway once again. After about 4 km (2.5 mi), Wanneroo Road terminates at a T-junction with Yanchep Beach Road, with the road (and State Route 60) continuing northwards as Indian Ocean Drive to coastal localities beyond the northern limit of the Perth metropolitan area (namely in the Wheatbelt region), such as Lancelin, Cervantes, and Jurien Bay. Indian Ocean Drive would eventually reach Brand Highway as the main route northwards to Geraldton.

A458 The A458 is a road from Halesowen, West Midlands, which then bypasses Shrewsbury, enters Wales near Middletown (near Trewern), and continues on to Welshpool, Llanfair Caereinion before ending at Mallwyd, Gwynedd. It is a single carriageway for its entire length in Wales. A494 The A494 or officially the "Dolgellau to South of Birkenhead Trunk Road", is a trunk road which spans from the terminus of the M56 near Saughall, Cheshire, the dual-carriageway then continues into Wales, crossing through to Queensferry, before reaching the Ewloe interchange with the A55, this section of the road from Saughall is part of the E-road E22. It then becomes a single- carriageway continuing through to Mold, and Ruthin, before multiplexing with the A5 near Corwen.

The N21 route commences about southwest of Limerick city, just beyond Patrickswell. At the junction, which is reached by the main M20 motorway, the N20 diverges south to Cork and the main dual- carriageway becomes the N21 west. Prior to the 2001 opening the new dual- carriageway, traffic to Kerry left the city on the old N20 in a southwest direction on the Ballinacurra Road through Raheen and then went through Patrickswell to the beginning of the N21. The new M20/N21 dual-carriageway route begins at junction 1 on the Rosbrien Interchange as the M20 where it leaves the M7/N18 Limerick Southern Ring Road, and bypasses the Limerick suburbs of Dooradoyle, Raheen and Patrickswell, and continues, as the N21, almost to Adare.

It passes without interruption under the M4 at the giant Coryton roundabout. For the next it is a modern high-speed dual carriageway by-passing Tongwynlais and Castell Coch, Taff's Well, to Pontypridd. Heading north to Abercynon, the road now follows the route of the Taff Vale Railways Llancaiach Branch to Quakers Yard roundabout, where it is joined by the A4059 from Abercynon, Aberdare and Hirwaun ; the A472 from Ystrad Mynach and Pontypool finally the A4054 from Quakers Yard, and Merthyr Tydfil. From Quakers Yard roundabout (locally known as "Fiddlers Elbow"), of dual carriageway takes the road to the Pentrebach roundabout where the A4060 links, and then to the Merthyr Tydfil roundabout where the road meets the A465 and the dual carriageway ends.

The dual-carriageway flyover at Old Town, seen from Ruskin Road Old Town is a small neighbourhood and main road next to Croydon in the London Borough of Croydon. The road is a dual-carriageway and forms part of the A236 which is a major A Road connecting both Mitcham and South Croydon. The road, heading from Mitcham, joins the A236 from Roman Way next to Reeves Corner tram stop and carries on the three lane dual-carriageway past Old Palace School and Central Croydon Fire station. After this is a roundabout which is a junction with the Croydon Flyover on the A232 road, then Old Town carries on for only a couple of metres where another smaller roundabout stands.

A road bypass of Staveley and Brimington has been proposed since 1927. When the A61 Rother Way (also known as the Chesterfield Bypass) was constructed in the 1980s, a short dual carriageway spur was constructed over the River Rother and the Canal, terminating at a large roundabout which has an access road to a supermarket and the single carriageway A619 continuing to Brimington. The dual carriageway was planned to continue, heading northwards through Wheeldon Mill Greyhound Stadium (since demolished) before crossing the Canal twice and following the course of the Rother through Staveley Works. There would have likely been a grade separated junction between Mill Green and Hall Lane to serve the town and the nearby village of Barrow Hill.

The eastbound carriageway was shifted to the western side, where the traffic switch is on March 1986. It was replaced by present concrete bridge in December 1987 for the westbound carriageway. The move facilitates better traffic flow for about 15 years before the North East MRT Line opens. However, several features of the iron bridge such as the decorative lamp posts and iron railings were incorporated into the current structure, in recognition of its historical significance.

The N18 continues north of the N19 junction where motorway regulations are enforced and the N18 route is designated as the M18 bypassing the towns of Newmarket-on-Fergus, Ennis and Gort. The motorway currently ends at Gort where the route continues as a single carriageway through County Galway. The dual-carriageway between Shannon and Ennis (including the Ennis bypass) was included in the second tranche of motorway redesignations and gained motorway status on 28 August 2009.

The project was led by Malaysian Public Works Department (JKR), Kuala Lumpur City Hall (DBKL) and the main contractor was Ahmad Zaki Resources Berhad (AZRB). This four-level interchange was opened to traffic on 26 February 2007. The 2-lane single-carriageway section between Bandar Baru Selayang and Templer's Park was upgraded to 4-lane dual-carriageway with emergency lanes and several U-turns. Construction started in 2006 and was expected to be completed in 2009.

The old Surtees Bridge partially cut away and removed Phase one of construction was to move the utilities and services. The construction method used was to demolish and build one carriageway at a time – the southern half was dismantled first whilst a contraflow system operated on the northern carriageway. During the early phases the condition of the eastbound section of the old bridge was monitored by contractor ITM and this was of particular interest during pile driving operations.

Two A-roads connect Southend with London and the rest of the country, the A127 (The Southend Arterial Road), via Basildon and Romford, and the A13, via Tilbury and London Docklands. Both are major routes, however, within the borough, the A13 is now a single carriageway local route, whereas the A127 is entirely dual carriageway. Both connect to the M25 and eventually London. No To Mob patrols warn motorists of the presence of active council parking enforcement CCTV vans.

The viaduct is newer than the at-grade section, having been completed in 2006. Despite what its name may suggest, the speed limit on the highway is less than that of an expressway. The highway also has a few traffic light junctions, something that expressways do not have. The at-grade section of the highway is a three-lane dual carriageway, and the viaduct is a two-lane dual carriageway with a 1-metre hard shoulder.

As of 2018, over 100km of the route is completed motorway or dual carriageway. The next construction planned is the M20 from Cork to Limerick, which has been allocated €850 million in government funds under the National Development Plan 2018-2027 capital scheme. The M20 will link with the planned Cork northern ring road, also forming part of the Atlantic Corridor route, connecting the planned Cork to Limerick motorway with the partially completed Cork-Waterford N25 dual carriageway.

The N7 gains limited-access freeway status again at the Melkbosstrand M19 interchange, which it will carry through to Malmesbury after roadworks are completed in 2020. Thereafter, the N7 is a single-carriageway highway with wide paved shoulders to Piekenierskloof Pass and through the Olifants River valley until Clanwilliam. The rest of the N7 to the Namibian border, through Vredendal and Springbok (where it meets the N14 National Route) is a single-carriageway highway with no paved shoulders.

After passing Stadium MK and crossing the H10, it becomes a dual carriageway once more and terminates in central Bletchley. The V8 Marlborough Street (B4034) runs from Stantonbury to Mount Farm in Denbigh East. It is a dual carriageway for most of length, as it is one of the more important routes. It runs in a cutting through Central Milton Keynes. , its planned connection to H10 Bletcham Way and the A5 remains neither built nor funded.

The A9 is a long branch which connects the Croatian-Slovenian border near Sečovlje with the city of Pula and services the tourist industry on the western coast of Istria. The sections between the border and Kanfanar are a single carriageway limited-access road; from Kanfanar to Pula it is a dual carriageway. There are two prominent object on this branch of Istrian Y: the viaduct "Limska draga" and the bridge "Mirna". The bridge "Mirna" is currently being tolled.

A55 links many of the main arterial routes within the city as well as creating a bypass of the often congested city centre and problematic A12 Westlink. Large sections of the route in east Belfast have been upgraded to dual carriageway standard with at-grade traffic light controlled junctions, together with off-road cycle paths alongside. However many sections (e.g. through Knock and from the Shaw's Bridge (Belvoir) to the M1) remain single carriageway, with four lanes of traffic.

The A446 starts as a dual carriageway south of Coleshill off the A452. It crosses the M6 at junction 4, almost immediately the road takes the course of the Coleshill bypass, the former route going through the centre of the town. There are 2 roundabouts on the bypass, one of which is the former route of the A47. North of Coleshill the route becomes single carriageway and runs parallel to the M42, eventually crossing it at junction 9.

Hansard 1967 To improve access to Chesterfield from the M1 to the south, a new section of dual carriageway was built. On the east-bound carriageway is the Esso Heath Service StationHeath Service Station with a Subway. The former route takes part of the B6039 through the parish of Grassmoor, Hasland and Winswick and Hasland in Chesterfield district; the A617 Hasland Bypass opened on 15 September 1978. There is a grade-separated junction with the B6425.

In the Isla de la Juventud, the dual carriageway from Nueva Gerona to La Fe is classified as motorway.

Road. The A19 dual carriageway, one of the two main north -south roads of the north-east of England, is about 1.5 miles away. Access to the A66 dual carriageway, a major transpennine route, is about 2 miles away. Bus. Arriva North East operate buses in Ingleby Barwick with regular services, day & evening, to Stockton seven days a week & Middlesbrough and Yarm Monday to Saturday. Rail. The nearest stations, Eaglescliffe, Thornaby and Yarm, are each about four miles away.

The second section was a short 700-metre section of four-lane dual carriageway completed in 1978. It extended southwards from the Andersons Bay intersection, across King Edward Street on twin bridges to connect with South Road near the Glen. The 1980s saw the extension of the motorway south from the Glen to Barnes Drive, bypassing Caversham. Due to funding constraints this section was only built as a single two-lane carriageway, albeit with no intersections.

The Hindhead Tunnel, opened in 2011, is part of the dual-carriageway Hindhead bypass that replaced one of the last remaining stretches of single-carriageway on the A3, the London to Portsmouth road. The bypass was constructed to improve road safety, reduce congestion and improve air quality. At in length, the tunnel is the longest non-estuarial road tunnel in the United Kingdom, and takes the road beneath the Devil's Punch Bowl, a Site of Special Scientific Interest.

At the southern end of the Leominster Bypass the A49 passes the Cadbury's Marlbrook chocolate factory. Shortly after, the A417 route to Gloucester begins at a junction shortly before the A49 makes its way up Dinmore hill past Queenswood Country Park. The south bound carriageway is 2-lane up the hill and the north bound carriageway is 2-lane heading up the other side of the hill. This can be a common section for accidents and skid-offs.

The Birkenhead alignment of the A59 utilises a disused railway cutting to link the road up to the M53 motorway. In Lancashire, the A59 was realigned during the same period in the early 1970s, to bypass the towns of Clitheroe and Whalley and was constructed as a single- carriageway despite parliamentary concerns that it would be less safe than a dual-carriageway. The bypass had been confirmed the year before at an estimated cost of £3.4 million ().

The highway, for the most part, follows the route of the existing single carriageway road, that is in various stages of disrepair. The Government of Kenya, through its parastatal Kenya National Highways Authority, plans to widen the road to a dual carriageway. As of January 2019, the design for the Kenol–Nyeri section was complete. At that time, it was expected that by June 2019, the design of the Nyeri–Isolo section would also be complete.

A substantial portion of the road surface had to be relaid. Further north, there is another section of 1970s dual carriageway road between Puckeridge and Buntingford, the contract for which was awarded to Meres Construction Ltd in April 1972. Buntingford was by-passed in the 1980s, however this is only single carriageway. From Buntingford, the road runs through the villages of Chipping, Buckland and Reed, before reaching the edge of Hertfordshire in the market town of Royston.

In Southend, the short dual carriageway Queensway bypasses the original route through the town centre, and while much of this is pedestrianised, it can be followed on foot. East of the town centre, Shoebury Road was bypassed by the single-carriageway Bournes Green Chase, just a few yards to the north, linking Southchurch with Shoeburyness. Finally, the terminus of the A13 has been truncated, the road formerly ending on Shoeburyness High Street at the railway station.

East of Chichester the road largely retains a two-lane dual-carriageway standard. There are, however a couple of sections of single-carriageway; at Arundel and at Worthing. These are both areas of known traffic congestion during times of peak usage. At the junction of the A27 and the A24, the A27 has a brief section where the road is designated 'A27' and 'A24' before continuing from the 'Grove Lodge' roundabout where the road is named "Upper Brighton Road".

It starts a descent into Rugby as a dual carriageway with 5 local access roundabouts. Approaching the Town Centre the road becomes single carriageway again and crosses under the West Coast Main Line. It passes the main Town Centre to the West and heads Southwards out of the town towards Dunchurch after which it passes over the M45 and once again becomes a rural road for its final length to terminate on the A423 Southam bypass.

British Airways Flight 38 which crash landed between the runway and the A30. During 2006 one of the main bottlenecks on the road was removed when the Merrymeet roundabout between Okehampton and Exeter near Whiddon Down was replaced with a grade-separated junction and dual carriageway. Since the Bodmin to Indian Queens project was completed in late 2007, the new dual carriageway runs to the north of Goss Moor. The previous road has been converted to a cycle lane.

Southbound, the freeway is divided into two carriageways, both of which provide access to the DVP. The outer carriageway also provides access from Sheppard and to Highway 401, including the westbound express lanes, while the inner carriageway is intended for DVP-bound traffic. The HOV lane also provides access to westbound Highway 401 via a dedicated tunnel, which passes beneath the other southbound lanes. To the east of Highway 404 is the Consumers Road office park.

Athi River has a railway station built in 1920 along the Uganda Railway, from Mombasa to Kisumu. There is also a new railway station on the Mombasa–Nairobi Standard Gauge Railway. Athi River is also linked to Nairobi via the Nairobi-Mombasa Highway (commonly known as Mombasa Road), a tarmacked dual carriageway, and to nearby Kitengela by Namanga Road, a tarmacked single carriageway.

In addition to its paved surface, the chaussee was characterised by a fully developed drainage system. The porous base course and gentle camber of the road surface assisted drainage, for which associated ditches (Chausseegraben) were dug alongside the road. Often the chaussee comprised a stone carriageway (Steinbahn) and a so-called summer track (Sommerweg). The stone carriageway was the paved section with a base course of gravel or broken rock as a subgrade and a covering of sand and loam.

Most of the original routing was destroyed by the Allies in World War II. By 1930 several US and European cities had built dual-carriageway highways, mostly to control traffic jams and/or to provide bypass routes for traffic. In 1932 the first German autobahn opened between Cologne and Bonn. It ran and became a precedent for future highways. Although it, like the first autostrada, did not feature a dual- carriageway design, it inspired the mass construction of future high-speed roadways.

The A1300 begins as the John Reid Road at the junction with the A194.

Unlike the other two motorway plans approved by the Croatian government, Zagreb-Split and Zagreb-Rijeka, which were cancelled after the suppression of the Croatian Spring, the Zagreb-Belgrade motorway plans remained in place and an expansion of the existing motorway into a dual- carriageway, six-lane motorway with exclusively grade-separated intersections proceeded. The additional carriageway was to be built south of the existing road, which was in turn to be widened to accommodate two traffic lanes and an emergency lane.

It extends for as far as a junction with the A132 near Wickford, whilst a slightly newer section south of there continues the route as a standard dual carriageway as far as a junction with a spur connecting to the old road (now A1245) and the A127 Southend Arterial Road a few miles west of Southend-on-Sea. The new road here more or less follows the same path as the World War II GHQ Line hence the many pillboxes visible alongside the carriageway between the Howe Green and the A132 junctions. An older section of dual carriageway extends as far south as the A13 at the Sadlers Hall Farm (Sadlers Farm), a roundabout near Benfleet. As with the A13 from London, the primary route section of the A130 ends here too.

Reid Highway in Westminster (between Wanneroo Road and Mirrabooka Avenue) has no street lighting and has attracted both antisocial behaviour and a number of accidents. The stretch between Beechboro Road and West Swan Road has been similarly criticised, and the area east of the Mitchell Freeway was prone to heavy congestion due to its limited capacity as a two-lane single carriageway, before being upgraded to dual carriageway. A four-lane dual carriageway extension of Reid Highway from West Swan Road to Great Northern Highway and Roe Highway was opened on 26 February 2010,Reid Highway Extension , Main Roads Western Australia completing State Route 3 as a highway-grade ring road around Perth. The extension runs parallel to Middle Swan Road, which has been retained as a local access road.

In the early months of 2005, construction of a major extension to Joondalup Drive was undertaken, extending from its then- northern terminus at Yandella Promenande, Tapping, to Neaves Road, Banksia Grove. The duplication and extension was necessitated mainly by the large traffic volumes that used the section of Joondalup Drive between Wanneroo Road and Hodges Drive during morning and evening peak hours, mainly caused by heavy traffic flows to and from the Mitchell Freeway at its then-northern terminus at Hodges Drive. The extension was constructed as a two-lane single carriageway, expanding to a four-lane dual carriageway in the vicinity of a major roundabout with Pinjar Road. It then reduced back to a two-lane single carriageway for the remainder of the road before intersecting with Neaves Road.

Work to create a compact grade-separated junction (Junction 45/Rougham) and to re-align a stretch of carriageway was completed in 2006. Vehicles over 7.5 tonnes traveling east were banned from using the outside lane on a dual two-lane section on a steep climb to Welford summit close to Junction 1 (A5199) from spring 2007; a similar scheme covered of the westbound carriageway from Junction 2, including a particularly steep climb to Naseby summit. The bans are active between 6am and 8pm, and are intended to reduce delays to other traffic from lorries attempting to pass on these climbs. Between 2007 and 2008 a new section of two-lane dual carriageway was constructed at the Haughley Bends, one of Suffolk's most notorious accident blackspots, to rationalise access using a new grade-separated junction.

In order to allow it to be built without closing the canal for the duration of the project, the canal was temporarily diverted to the south of its existing route, from the head of Semington Top Lock to a point to the east. Since the towpath is on the north bank of the canal at this point, temporary foot bridges were built over the canal, so that the towpath could follow the diversion, and avoid the work site. The road was planned as a dual carriageway, with the structure resting on piers at both ends protected by wing walls and a pier built on the central reservation protected by safety barriers, but only one carriageway was built and there is no central pier. The area where the second carriageway would have been is grassed.

When first designated in 1922, the A350 ran only from Warminster to Poole.1922 road list By 1948 the road had been extended north from Warminster to Chippenham on the former routes of the A363 and the A364.1948 Ordnance Survey map In the 1990s the road was extended north from Chippenham to the M4 motorway by renumbering the A429. The Chippenham bypass was built in the 1990s as a single carriageway and was designed for future widening to dual carriageway. Work to dual the section between Chippenham Golf Club, where the original dual carriageway from the M4 motorway narrowed, to the Badger roundabout was completed in 2014, and the section from Brook roundabout to Bumper's Farm roundabout, the junction with the A420 Bristol Road, was completed in 2016.

The route becomes dual carriageway on the approach to Cork. New relief roads in Cork bring the route into the city centre while avoiding the winding streets through which the route ran until around 2000.

The plan proposes widening the southbound carriageway into the adjacent Sir John Oldham Park. The required amount of land is described as "small portions along the edge". The project is still in the planning phase.

The bridge has a carriageway is about 3 metres wide. Rough masonry parapets with upright stone copings. The parapets are turned out at all four ends. Road macadamed and blocked by bollards at each end.

Towards evening things got out of control, people breached fences and entered on the carriageway, blocking traffic. Next day, the Gendarmerie fined or queried 106 people for disturbing public peace and destruction of public domain.

Map of the tunnel (blue) with the connection on the Akershus side to the E6. The red line shows the second, proposed tube and carriageway. The Public Roads Administration announced on 10 January 2012 that they intended to build a second tube for the tunnel along with a second carriageway on the section of National Road 23 from the tunnel to the Vassum Interchange on E6 in Frogn. The investment was proposed financed through an extension of the toll collection for an additional twelve to fifteen years.

The Line 1 stations are the main landmarks of the avenue; there are nine of them at Rizal Avenue. At the northern end of the avenue is the Bonifacio Monument roundabout. Vehicles coming from Rizal Avenue's northbound carriageway can turn right into EDSA (Circumferential Road 4); its northern logical extension would be the MacArthur Highway (continuation of Radial Road 9), which leads all the way to Laoag, Ilocos Norte. Vehicles from Samson Road (EDSA's logical western extension) enter the avenue to its southbound carriageway.

The double- deck carriageway design of Kerinchi Link from Bukit Kiara Interchange Exit 2310 to Kerinchi Interchange Exit 2310 was made as a result of the early controversial issues during the development stage. The construction of the stretch took place at the border of Universiti Malaya, which meant that the construction could take up some of the university area, which sparked complaints. As a result, the expressway concessionaire Sprint came up with the idea of a double-deck carriageway which could reduce the land usage.

Continuity of a dual carriageway on the entire ring road should emerge on the horizon in 2018 as part of the 2014-2018 plan. Indeed, three grade separated roundabouts are planned as part of this dual carriageway urban boulevard project: Moutiers, La Gineste and Saint-Marc. Finally, the principle of a large bypass has not been excluded (without a deadline, to date). In 2009, the Rodez-Aveyron Airport experienced changes with the expansion of its terminal and the opening of new international scheduled destinations.

The N3 from Cedara (in-between Hilton and Howick) to Heidelberg in Gauteng is managed by a private concessionaire, the N3 Toll Concession. A few kilometres after the N11 interchange, the N3 is tolled once again; the dual-carriageway freeway also ending at this point. From here, the N3 ascends the South African plateau via Van Reenen's Pass; at the top of the pass, the N3 crosses into the Free State. A section of the N3 in the KwaZulu-Natal Midlands, showing the dual-carriageway freeway.

It begins at the Potsdam interchange at the N7 in the north; then proceeds southward and becomes a dual-carriageway at Blaauwberg Rd and is called Koeberg Road through this section. At the Koeberg Interchange with the N1, the M5 becomes a limited access motorway and is called the Black River Parkway. At the N2 interchange, the name changes to the Kromboom Parkway. Just south of the Ottery Road interchange, the M5 loses its motorway status and is a dual-carriageway as Prince Georges Drive.

A short distance after this point it reduces to single carriageway as it passes the industrial estates of Mount Farm and Fenny Lock. At the end of this one-kilometre stretch the road crosses under the A5 at an unusual bi-graded triple roundabout, the eastern part of which forms a dogbone interchange. From here it reverts to being dual carriageway and takes on the designation of A4146. It remains like this for two grid stretches before the A4146 turns off onto the V11 Tongwell Street.

500x500px Kelana Jaya LRT station is also a rapidKL bus hub for the surrounding areas of Petaling Jaya. To serve this purpose, there is a major bus stop located opposite the expressway on the northbound carriageway, linked to the station by a pedestrian bridge. Buses depart from the station on the southbound carriageway, but many buses drop their passengers at the bus stop as this avoids congestion in the station bus terminal. This station also offer a bus route to Bandar Utama MRT station.

Latitude and longitude coordinates are N 52 degrees 42 minutes 10.2 seconds W 001 degree 19 minutes 22.2 seconds. (These coordinates may also be expressed as N 52 degrees 42.170 minutes W 001 degree 19.370 minutes or as N 52.7028 degrees W 001.3228). Ordnance Survey National Grid Reference is SK 45911 11955 (expressed as an all-numeric reference: 445911, 311955). The chapel fronts the eastbound (Leicester-bound) carriageway of the A 511 dual- carriageway main road (Shaw Lane), 1.4 miles west of M1 Junction 22.

Flood bridges to the east and west have seven smaller and lower segmental brick arches. A separate bridge was built for the southbound carriageway when the road was dualled in the early 1960s. The A1 Trunk Road (Tempsford Junction Improvements Slip Roads) Order 1999 authorised the construction of new slip roads to access the A1 and the scheme was completed in 2001. A slip road from the southbound carriageway joins the road from Little Barford, which was extended south through Tempsford Hall Park to a new roundabout.

The N17 bypass opened in July 2001 to the relief of thousands of motorists. Journey times at peak periods were reduced by 30 minutes on the Galway/Sligo route after the opening. The project was built as a grade separated single carriageway (motorway style interchanges) which is unusual for single carriageway bypasses in Ireland. The new 16 km road bypassed one of Irelands most treacherous national routes, the original 7 mile stretch between Claremorris and Knock had a very high accident rate due to its poor alignment.

R449 northbound The R449 road is a regional road in County Kildare, Ireland. It is just long and was completed in 2003 as part of the construction of a grade separated interchange to connect both West Leixlip and North Celbridge to the M4 motorway at Junction 6. The 2 km section between Leixlip and the M4 is dual-carriageway. The speed limit along this section is 60 km/h, despite joining an 80 km/h road with 120 km/h road, via a dual carriageway.

Before 2012 there was no section of A1 (M) motorway between the junction for the A168 and Barton, just after Scotch Corner. This is where the old A1 road was sandwiched between the sections of the A1(M). It used to be in a Primary road Dual Carriageway standard use of junctions and 'give ways'. When the A1(M) was built there was no need of it any more so it was downgraded to a secondary status ripped down to a single carriageway standard.

The N2 commences at junction 5 of the M50 motorway. It then runs as a dual-carriageway for 17 km (10.5 miles) from the M50 to north of Ashbourne, County Meath. This project was opened on 25 May 2006, and includes 3.5 km (2.2 miles) of three lane dual carriageway built to motorway standard. The route is the first to have a 120 km/h (75 mph) special speed limit (this was previously reserved for motorways, see Road speed limits in the Republic of Ireland for particulars).

Albany Highway commences at The Causeway, a river crossing that connects to Perth's central business district. The highway heads south-east through Perth's metropolitan region, and continues through the southern Wheatbelt and Great Southern regions to Albany on the south coast of Western Australia. Albany Highway is generally a two-lane single carriageway road, but with additional lanes and dual-carriageway sections in Perth and Albany. The highway is allocated State Route 30, except for bypassed sections in Perth, and the southernmost portion in Albany.

The section from junction 38 of the M62 (its terminus) to the A1034 junction near South Cave was single carriageway before the M62 opened in May 1976. The section was constructed as the dualling of the Caves Bypass and opened when the last eastern section of the M62 opened, completing the dual carriageway link to the outskirts of Hull. From junction 38, the B1230 leads to North Cave (and in the direction of Beverley) along the former A63. The BP Triangle North Cave is alongside the junction.

The road starts on the A4540 Birmingham Ring Road, bypassing Small Heath and crossing the B4145. It passes over the River Cole and meets the A4040 at a grade-separated junction at the Swan Shopping Centre in Yardley. It meets the B425 at traffic lights in Sheldon, then enters the borough of Solihull. The section of the A45 from Birmingham city centre to the M45 is all dual carriageway — urban dual carriageway with traffic lights until Birmingham Airport, then rural grade-separated between the airport and Coventry.

The road begins at a roundabout with the A629 Skipton to Rotherham road in Keighley. The B6265 road (which was formerly the A629 until the bypass to Skipton was opened) also filters into the roundabout. The road heads south along the edge of Keighley town centre and is single carriageway until it intersects with the A6035 spur road heading south through the town. The road then becomes dual carriageway and arrives very quickly at the next roundabout with local roads in the Aireworth suburb of Keighley.

Ginninderra Drive is a major arterial road in the northern suburbs of Canberra, the capital city of Australia. The road provides an important access corridor to facilities including the Australian Institute of Sport, Canberra Stadium, the University of Canberra and Belconnen Town Centre. It is built to a dual carriageway standard carrying two or three traffic lanes in each direction for most of its length, with a speed limit of . A short section from Charnwood to Dunlop is single carriageway with a speed limit of .

The Kerenzerberg Rail Tunnel is a rail tunnel in the Swiss canton of Glarus. The tunnel is long, and carries the Ziegelbrücke to Sargans line under the Kerenzerberg Pass to the south of the Walensee. Prior to 1960, the railway used a route along the shores of the Walensee and through shorter tunnels. The trackbed of this route is now used by the westbound carriageway of the A3 motorway, with the eastbound carriageway using the Kerenzerberg Road Tunnel that runs roughly parallel to the rail tunnel.

The N19 road is a national primary road in Ireland, connecting from the N18 Limerick-Ennis-Galway road to Shannon Airport. It forms part of European route E20. The route in its current form consists mostly of a dual-carriageway passing around Shannon Town, which starts at an interchange near Hurlers Cross on the N18 road. The dual-carriageway ends on the far side of Shannon Town at the Shannon Free Zone industrial estate, and proceeds as a two lane road to the airport.

The A508 is a short A-class road for north/south journeys in south central England, forming the route from Market Harborough in Leicestershire, via Northampton, to Old Stratford, just outside Milton Keynes. The road begins in the centre of Market Harborough and crosses into Northamptonshire just outside the town. Crossing the A14 at Kelmarsh, it continues on through the centre of Northampton, merging with the A5199 as it enters the town. Through Northampton the road repeatedly switches between being a dual carriageway and a single carriageway.

Following Roe Highway, the freeway continues its journey south, between the residential areas of South Lake and Jandakot. Houses east of the freeway surround the Glen Iris Public Golf Course. The same view facing south at Cockburn in September 2019. Note the additional lane in the southbound carriageway with the northbound carriageway in the process of being widened After there is a diamond interchange with Berrigan Drive, after which the freeway passes lower density lots in Cockburn Central and the industrial section of Jandakot.

As part of the SR 520 Bridge Replacement and HOV scheme, WSDOT plans to implement junction control through hard shoulder running. Based on traffic conditions, ATM will open the shoulder as an auxiliary lane on the SR 520 westbound carriageway across Portage Bay Bridge, which will turn the motorway section from a 3 + 2 to a 3 + 3 dual carriageway. The additional capacity will allow traffic from the Montlake Boulevard junction more room to merge. The shoulder running can also be activated for incident management.

The upgrade of the N1 is now complete in the Republic of Ireland, the first major route to be completely upgraded to motorway/dual carriageway standard (outside of Dublin city centre) as per the National Development Plan. The Northern Irish authorities have no plans to replace the A1 route (currently dual carriageway) with motorway, although many junctions have now been grade separated. Currently, to drive from Dublin city centre to Belfast, one travels along the M1 (Republic of Ireland), N1, A1 and M1 (Northern Ireland).

Benara Road starts off at a roundabout with Camboon Road in Noranda as a two-lane, single carriageway road with a speed limit of . The road continues east, in a completely straight line, passing Noranda Shopping Villiage. from the western terminus, just before Holden Drive, Benara Road turns into a four lane dual carriageway, and the speed limit changes to , which is what the speed limit is for the rest of the road. from Holden Drive, Benara Road passes over Tonkin Highway as a bridge.

In 2017 work started on the widening of 13.5 km of the existing two-lane dual carriageway to D3M standard between the Maudlin's interchange (J9) and the M7/M9 junction (J11). The widening project will include relocating the existing on/off ramps at Junction 10 to a new junction at the main Naas to Newbridge dual carriageway (R445). A new interchange at Osberstown between junctions 9 and 10 which will be built and designated Junction 9a. The project is due to be completed by 2020.

The state highway continues east as a two-lane two- way road on the southern of two carriageways; the northern carriageway is unused. SR 114 continues in this formation to the New River, where the two- lane highway crosses the river closely paralleled by a closed through truss bridge to the north. Once in Montgomery County, the state highway crosses over Norfolk Southern Railway's Christiansburg District. The westbound carriageway becomes used again just west of the entrance to the Radford Army Ammunition Plant in Centerville.

Feering is close to the A12 and M11 (the latter via the A120). The village has recently been affected by the A120 proposal to construct a dual carriageway to the north of the village. This extension of the dual carriageway section of the A120 will stretch from the current A12 near Marks Tey to Braintree "cutting travelling time to Stansted by 10 minutes". The Highways Agency has not released information concerning new routes, which has angered some local residents, who oppose the new proposals.

The N73 is 32 km long. On 25 May, 2009, a Mitchelstown bypass (section of the single carriageway N8 road) was redesignated the N73 when the Mitchelstown-Fermoy section of the M8 motorway opened to traffic.

State Highway 53 (SH 53) is a New Zealand state highway linking at Featherston with Martinborough. The highway is a 17.8 km long two lane carriageway and forms part of the Classic New Zealand Wine Trail.

Before the West of Albert reclamation project in the 1990s, the A1 used to travel along the entire length of the Esplanade Road as a dual carriageway, then form a gyratory around the former abatoire building.

At the time of the crash the Arizona Department of Public Safety was already responding to reports of a Nissan pick-up truck travelling at speed in the wrong direction going eastbound on the westbound carriageway.

The headquarters is situated in the south of Luton off the dual- carriageway Airport Way (A1081), close to junction 10a of the M1 and Luton Airport Parkway railway station, opposite Lower Kidney Wood near Luton Hoo.

The Sturt carries the National Highway 20 shield for its entire length, the majority of which is a single carriageway and freeway standard and 6-lane arterial road standard towards its western terminus, north of Adelaide.

In April 1977, the government announced that the national speed limits for single-carriageway roads was to be increased to and that the speed limit was to be restored on dual-carriageways on 1 June 1977.

Jalan Utama Berakas is a dual carriageway divided road in Brunei-Muara District, Brunei. The road passes through the town of Lambak Kanan in Berakas. The speed limit on the entire stretch is 80 km/h.

Seen from Arundel Gate. Leader House is a Georgian townhouse located on Surrey Street in the city centre of Sheffield, England. It overlooks the busy Arundel Gate dual carriageway and is a Grade II listed building.

The proposal was to utilise vacant scrub land and create a new larger car park that joined the A4042 dual carriageway that runs parallel to the station. As of September 2018 no decision has been made.

The A38 road runs through Quedgeley, now as a dual carriageway running between Gloucester city centre and the M5 motorway at junction 12; the old route taken by the A38 through Quedgeley is now the B4008.

Most sections of the federal highways are only single carriageway with one lane for each direction and no hard shoulder pull-out area. The closest equivalent in the United States would be the U.S. highway system.

After the railways developed by the Italians fell into disrepair, the major transport routes to and from the port are either accessed by sea or major dual carriageway roads. Air access is via Benina International Airport.

Now the most important road in Perth's coastal suburbs, Marmion Avenue was duplicated up to Whitfords Avenue. In early 1986, it was assigned State Route 71, and from then on was gradually extended as a single carriageway road further north - extending first to Prendiville Avenue (just north of Ocean Reef Road), to Burns Beach Road in 1991 and to Quinns Road in the mid-1990s. Marmion Avenue was finally duplicated to its terminus in 2001, with the last portion being the empty stretch between Burns Beach Road & Quinns Rocks. In 2000 and 2001, Reid Highway was extended as a two lane road from its terminus at Mitchell Freeway to Marmion Avenue, providing another link to the east. This section was later upgraded to a four-lane dual carriageway in 2015-2016. After delays due to disagreements at State Government level about what route the road should follow, Marmion Avenue was extended further north to Yanchep and opened to traffic in November 2008. The extension opened as a single carriageway, but earthworks have already been undertaken to enable conversion to dual carriageway at a later date, which eventuated starting from 2018.

This intersection marks the beginning of the Bloemfontein Western Bypass, which is the first freeway section on the route since Paarl. The N8 WEST from Kimberley intersects with the N1 bypass, joining it for 3 km, before heading EAST through the central parts of Bloemfontein and then to Maseru in Lesotho. The N1 is signed as a toll road from the N6 interchange until its end at Beit Bridge. The N1 becomes a single carriageway freeway a few kilometres north of Bloemfontein after passing the R30 to Brandfort; however, construction work is in progress to extend the freeway for another 20 km by building a second carriageway. Once the freeway ends, the road will be a single carriageway but with two lanes in each direction until 5 km before the toll plaza at Verkeerdevlei, halfway between Bloemfontein and Winburg.

None of the Sturt Highway was originally constructed as dual-carriageway, however work commenced in January 2007 to upgrade the highway to two lanes each way dual carriageway between the Gawler Bypass and Greenock in the Barossa Valley. The project was completed in 2010 with budget savings directed towards further Sturt Highway improvements. The Northern Expressway, also named as the Max Fatchen Expressway in 2013, was built at the south-western end of the Sturt Highway, extending Route A20 by 22 km from Gawler southwest to meet Port Wakefield Road (National Route A1) at Waterloo Corner as part of an AusLink/South Australian Government project to build a new dual-carriageway/freeway standard road as part of the North–South Corridor project. This will provide better access for road transport to Port Adelaide and the industrial areas west and northwest of the city.

This pattern has been simplified today, but the essentials of the scheme have been retained. The 1935 photograph shows a couple of small trees along the "instep" of the carriageway curve, but it is doubtful that they were the same Crepe Myrtles present there today. One notable feature is that a side path led off the left of the carriageway towards the engine house and swimming pool, while a curved bed and path linked the tennis court to the point where the carriageway came closest to the house. The principal adornment to the House's garden during the 1930s, following its acquisition by Mr A. A. Gregory in 1933, was an elaborate pergola and lattice construction on a low earth platform in the southern sector of the garden, adjacent to the kitchen block and former dining room.

The highway begins at Lyndhurst interchange, where the South Gippsland Highway and the alignment of the South Gippsland Freeway meet, outside Lynbrook; Western Port Highway is linked directly to the southern end of the South Gippsland Freeway by an overpass over the South Gippsland Highway. From the interchange, Western Port Highway runs south as a two-lane (each way), dual carriageway, overpassing the Cranbourne railway line, passing through a set of traffic lights at Moreton Bay Boulevard, and passing through roundabouts at Glasscocks Road, and Thompsons Road; between here and Lyndhurst interchange the highway is designated route M780. The highway runs onwards further south through roundabout intersections with Hall Road, Ballarto Road and Cranbourne- Frankston Road. The road continues south to North Road, as a dual carriageway but designated as route A780, before reverting to a dual-lane single carriageway road to Hastings.

From its eastern terminus between Redcar and Middlesbrough it runs past Stockton-on-Tees and Darlington mainly as two-lane dual-carriageway and single carriageway past Darlington, becoming motorway standard as the A66(M) shortly before meeting junction 57 of the A1(M). It shares the A1(M) route south to Scotch Corner, from where it continues west across the Pennines, past Brough, Appleby, Kirkby Thore, Temple Sowerby and Penrith until it reaches Junction 40 of the M6 motorway at Skirsgill Interchange, where traffic going towards Western Scotland turns onto the northbound M6. The A66 continues past Blencathra to Keswick and Cockermouth and on through the northern reaches of the Lake District before arriving at the coastal town of Workington. There is a short stretch of dual carriageway along the northern part of Bassenthwaite Lake between Keswick and Cockermouth.

Upgrades to the specified roads were completed in 2010. In addition, a new motorway – the M50 – was built around Dublin. Where a section of national primary road is designated a motorway, signage is white-on-blue instead of white-on-green, in addition, the prefix "N" is dropped, and replaced with "M" instead on road signs. A high quality dual carriageway may be redesignated a motorway by means of an order under the Roads Act 2007. In addition to the major inter-urbans, the N11, N17, N18, N20, N21, and N25 – all of which form links between regional cities or other strategic links – also have major sections of good standard dual carriageway (in the N18's case, the entire route is made up of dual carriageway and motorway since 2017), with some sections of motorway also in place.

The road begins on the edge of Poole by the border with Bournemouth, before heading northward as a grade separated dual carriageway, one of the main roads in the South East Dorset conurbation. From near Bournemouth International Airport it follows the western side of the Avon valley, joining the route of the A31 road heading north-east for to cross the valley, before turning left at Ringwood in Hampshire where it joins the original, single carriageway route to the east of the river. Heading northward up the east side of the Avon, it crosses to the west again near the town of Fordingbridge. After crossing into Wiltshire near Downton, it meets the A354 road at a roundabout near Britford on the southern outskirts of Salisbury, before joining the route of the A36 road as it bypasses the city centre to dual carriageway standard.

The R154 road is a regional road in Ireland, linking the R147 near Clonee, County Meath to Crossdoney (near Cavan) in County Cavan. The road is single carriageway throughout. Many parts of the route have dangerous bends.

The V9 Overstreet is the shortest of all the 'V' roads, it runs from H3 Monks Way to H5 Portway. It is single carriageway the entire distance. It serves Downs Barn, Downhead Park, Neath Hill and Pennyland.

The one-way road (formerly original dual-carriageway highway) from Chin Swee Temple designed for climbing route to the summit, while the other one-way road from the summit designed for downhill route to Chin Swee Temple.

The speed limit for the majority of the highway is 70 km/h with two small 60 and 80 km/h sections at the Scarborough end. The highway is a dual carriageway for most of its length.

Rural Economy and Connectivity Committee 05 December 2018: Aberdeen Western Peripheral Route, Scottish Parliament reports, 5 December 2018 The project also included an upgrade to the dual carriageway of the A90 further north between Balmedie and Tipperty.

Until 8 October 1960, trams of the Sheffield Tramway ran from Sheffield City Centre along Abbeydale Road to Millhouses terminus. The road has been converted to a dual-carriageway from Millhouses to the Baslow Road railway bridge.

Winthrop Avenue remained poorly constructed in 1939, with calls for it to be upgraded to dual carriageway standard. In 1940, a plan for construction of the second carriageway was announced by the King's Park Board, the Perth City Council and the Subiaco Municipal Council. The councils would be jointly responsible for the building of the road, with the King's Park Board responsible for the clearing of vegetation. The resumption of a strip of land along the edge of the park needed for the works was approved by an Act of Parliament.

The Brooklyn Bridge is a concrete girder bridge that carries the Pacific Motorway (M1) across the Hawkesbury River between to Point, located north of Sydney in New South Wales, Australia. The bridge comprises a dual carriageway with three lanes in each direction of motorway grade-separated conditions. The adjacent Peats Ferry Bridge carries the Pacific Highway (B83) across the Hawkesbury River in a single carriageway with one lane in each direction in state highway conditions. The Peats Ferry Bridge permits the carriage of pedestrian and bicycles; not permitted on the Brooklyn Bridge.

A similar interchange exists in Coal Grove, Ohio at the junction of US 52 with the Ben Williamson Memorial Bridge and the Simeon Willis Memorial Bridge, which cross the Ohio River and lead to and from Ashland, Kentucky, respectively. The eastbound carriageway of US 52 passes under the interchange, with left-hand exit and entrance ramps to the bridges. The westbound carriageway of US 52, which narrows to one through lane, has a continuous green T-intersection with the bridges. The ramps cross each other at-grade, with a traffic light-controlled intersection.

Recently, the construction of Pan-Borneo Highway is approved under 2015 Malaysian Budget. The highway project spans 1,663 km (936 km in Sarawak, 727 km in Sabah) mostly mirror the existing trunk road, and it involves the widening of the present three-metre-wide single-carriageway into a dual- carriageway. Driving on the left has been compulsory since the introduction of motor vehicles in Federated Malay States in 1903 during British colonial era. It is estimated that 9,432,023 passenger cars is actively using this road network in 2018.

At Glen Huntly Road, the speed limit increases to 80 km/h and the road widens to become an eight-lane divided highway. It is reduced to six lanes at Moorabbin, passing through Cheltenham and Mentone, and then to the 60 km/h or 70 km/h four-lane single carriageway after the roundabouts at Mordialloc. The highway then travels virtually along the foreshore of Port Phillip Bay, to Frankston, with several stretches of dual carriageway, and then up Olivers Hill, from which there are good views across Frankston and the bay.

In particular, dualling of the A30 has relieved most of the congestion as towns along the route which were formally bottlenecks have been bypassed. Notable schemes include: Launceston bypass (1975); Bodmin bypass (1977); and the Fraddon and Indian Queens bypass and associated A39 spur(1995). The most recent scheme is 7 miles of new dual carriageway to the north of Goss Moor. Opened in July 2007, the new road relieved a notoriously congested single carriageway stretch which included a bottleneck at the bridge carrying the Par-Newquay railway over the road.

There is also a class III bicycle route, which has roadside signs suggesting a route for cyclists, and urging sharing the road. A class IV separated bike way (Caltrans) is a bike lane that is physically separate from motor traffic and restricted to bicyclists only. In France, segregated cycling facilities on the carriageway are called bande cyclable, those beside the carriageway or totally independent ones piste cyclable, all together voie cyclable.French bicycle association FUBi, Pistes et bandes cyclables In Belgium, traffic laws do not distinguish cycle lanes from cyclepaths.

Welshpool Road East (9.5 km long) had an East suffix added after the road's disconnection. At a similar quality to Welshpool Road, its 4-lane section is an entire dual carriageway; it changes to a 2 to 3 lane single carriageway after climbing most of the Darling Scarp, however. With only 4 traffic lights in total (two of those at Roe Highway's diamond interchange), traffic problems are relatively minor, the only congestion being towards Roe Highway westbound. Allocated State Route 8, Welshpool Road East starts as an extension of Orrong Road.

The road starts again slightly further south off the A638 and A614, and heads east of Bawtry passing under the East Coast Main Line railway as Gainsborough Road. It then crosses the River Idle at Bawtry Bridge and enters Nottinghamshire and Bassetlaw. The road bends to the right and becomes dual carriageway as it bypasses the village of Scaftworth, which has two exits to the right. It bends to the left and continues as the single carriageway Bawtry Road (passing SPECS average speed cameras) through Everton, with Harwell on the left.

Heading eastbound, the M5 provides access to Sydney Airport and the CBD; while the M7 provides access to Newcastle and Brisbane bypassing the Sydney CBD. Both of these routes are tolled. Other than sections within the urban areas of Sydney and Melbourne, the Hume Highway is dual carriageway or expressway standard for its full length in Victoria and New South Wales. Although the full length of the Hume Highway is dual carriageway (with at- grade intersections and restricted entry from adjoining land), there are considerable lengths of the highway which are of full freeway standard.

The construction of Haskovo- Harmanli section began in July 2011 and was completed on 28 May 2015. A long second carriageway near Svilengrad was inaugurated on 7 June 2015, while the other carriageway had been built during the 1980s. The last remaining section, between Chirpan and Haskovo, entered service on 29 October 2015. The construction of the Chirpan-Haskovo and the Haskovo-Harmanli sections of the motorway were co-funded by EU funds allocated for Bulgaria, while a small section at the Turkish border was co-funded with a loan from the IBRD.

The Western Highway is the Victorian part of the principal route linking the Australian cities of Melbourne and Adelaide with a length of approximately of single carriageway then of dual carriageway known as the Western Freeway. It is a part of the National Highway network and designated as National Highway A8 and M8. The western end continues in South Australia as the Dukes Highway, the next section of the Melbourne–Adelaide National Highway. The Western Freeway joins Melbourne's freeway network via the Western Ring Road, in the middle western suburbs of Melbourne.

Burwood Highway is a primary route between Melbourne and the eastern suburbs, and the area around Belgrave. It begins at its junction with Monash Freeway (or CityLink if travelling north) as a four lane single carriageway, which is often clogged with heavy traffic, as well as trams travelling along the roadway for some of the route. However, this part of the route is usually signed as Toorak Road. After Warrigal Road, the highway widens to become a six lane dual carriageway, the median with trams tracks, carrying the Route 75 service to Vermont South.

As of July 2011, the entire motorway route is completed, consisting of a dual-carriageway and four traffic lanes, except for a relatively short segment which is still a single carriageway road. The motorway is currently operated by Autocesta Zagreb - Macelj. The motorway carries a considerable volume of traffic throughout the year; however, in the summer, its peak volume is nearly double the average, as traffic intensifies because of tourists travelling to Adriatic Sea resorts and back. Furthermore, the southernmost sections of the motorway serve Zagreb's sizeable suburban traffic.

Those sections were the first modern motorways to be built in Croatia and Yugoslavia. Due to political upheavals in Croatia and Yugoslavia, construction of the motorway was labeled a "nationalist project" and, along with the proposed Zagreb–Split motorway, was cancelled in 1971. After the Croatian War of Independence, efforts to build the motorway were renewed and construction resumed in 1996. In 2004, a two-lane, single carriageway expressway was completed between the sections completed 25 years previously, and the second carriageway was built; the motorway was completed on October 22, 2008.

South of the Sadlers Farm roundabout, the final leg of the A130 continues as a non-primary single-carriageway route into Canvey Island on the River Thames. Canvey Way is a causeway connecting "mainland" with island, and connects with the older road through the island, the B1014. On the island itself, a final short stretch of dual carriageway leads to the built-up area where the road turns east and becomes single, before meeting the B1014 again at a one-way system in the central area, incorporating the High Street.

It was then dismantled, turned around and used to bore a second tunnel for the southbound carriageway. The machine, designed by Herrenknecht of Germany, was 156 m long, 12 m in diameter and was delivered to Dublin port in 105 parts carried by three ships, taking one week to unload. Combined, these bores resulted in the removal of 500,000 m³ of rock. A similar process was followed northwards by the 60 m long TBM-2 "Meghan" boring from Collins Avenue to Whitehall Church, first creating the southbound carriageway.

DN5 () is an important national road in Romania which links Bucharest with the southern country border with Bulgaria by the Giurgiu Russe Friendship Bridge. DN5 has been designated as a priority express road, being upgraded between 2006 and 2009. Between Bucharest and Giurgiu, for the most part, it is a non- grade separated dual carriageway with no emergency lane, with entrances and exits from adjacent roads using roundabouts. Some segments (such as the Adunații-Copăceni bypass) are constructed to full motorway standard (dual carriageway, full grade-separation, wide median separation).

The old N3, between Clonee and Dunshaughlin The route, known as the Navan Road as it leaves Dublin, starts at its junction with the M50 motorway (Junction 6) and then bypasses Blanchardstown, Mulhuddart and Clonee with a dual carriageway. The dual carriageway changes into the M3 motorway near the Meath border by-passing Dunshaughlin and Navan. Near Kells the route continues as the N3 dual carriage way to the border with County Cavan. It then passes through Virginia, past Cavan Town and continues past Butlersbridge and through Belturbet.

SH 18 begins at the Auckland Northern Motorway and runs southwest as a dual carriageway road, and is coextensive with the Upper Harbour Highway, which after two kilometres becomes a motorway at the Albany Highway interchange. This four- lane section of motorway opened in December 2007, and bypassed the single carriageway Upper Harbour Drive. The motorway heads south-west, crossing the upper reaches of the Waitematā Harbour over the Upper Harbour Bridge. At Squadron Drive, the highway extends onto a new section of motorway, which opened in August 2011, bypassing Hobsonville Road.

Although most of the island's roads are owned by the island council (cabildo insular), roads of major importance such as the LZ-2 are owned by the Government of the Canary Islands. The road is a dual carriageway, with two lanes in each direction, between Arrecife and Tías (approximately ); the rest of the route, between Tías and Playa Blanca (approximately ) is a single carriageway. As of July 2019, there are two fixed speed cameras on LZ-2, on kilometre 1.2 in both directions; the speed limit at this point is .

The remainder of the highway is a two-lane single carriageway until Kalgoorlie, where a dual carriageway exists. The speed limit is from The Causeway to Midland, near the bottom of Greenmount Hill, and from Greenmount to Sawyers Valley. From the eastern edge of Perth it is generally , but with lower limits for sections near the towns the highway encounters en route to Kalgoorlie. sign The highway runs mostly parallel to the Mundaring to Kalgoorlie water pipeline, which supplies the Goldfields with water from Mundaring Weir in the eastern part of Perth.

Although the GRA was initially planned and built as a single-carriageway road, it was soon clear that traffic was rapidly growing well beyond the expectations. Upgrade works to motorway standards started in late 1950s with first dual-carriageway, four-lane section (Salaria to Tuscolana) opened 1962. Further works were carried over throughout the 1970s, and by 1979, the remainder sections were upgraded to four-lane and the entire ring classified as toll-free highway. Upgrade works to 6-lane started in 1983 and were completed in stages throughout the 1990s and 2000s.

There were proposals to upgrade this section of A21 to a dual carriageway standard following the Pembury bypasses completion, however they were delayed multiple times. In the 2000s, an upgrade scheme was proposed by the Highways Agency, and in 2013 it underwent public enquiry. The scheme layout followed the existing carriageway and involved the construction of a pedestrian and cycle route along its whole length, as well as upgrading the Longfield Road roundabout into a grade-separated Roundabout interchange. £92million of government money was made available to the scheme in July 2013.

The remaining section of single carriageway east of Mitchell Freeway, between Altone Road and West Swan Road, is being converted to dual carriageway with completion due mid-2020. Part of the features include a bridge connecting the northern and southern sections of Arthur Street and a second right-turning bay from Reid Highway westbound to West Swan Road northbound. In December 2019, funding was assigned for developing a project for full grade separation of the last remaining signalised intersection on the section between the Mitchell Freeway and Tonkin Highway, at Erindale Road.

At Ormskirk, it reverts from a dual to single carriageway on an old bypass. The road follows through Burscough and Rufford, despite a bypass being considered for this section in the early 1980s, before reaching the A565 at Tarleton. The road continues over the Leeds and Liverpool Canal and River Douglas through to Longton (and Hutton) bypass, where it returns to dual carriageway. Passing Lancashire Police HQ, the road bypasses Penwortham and continues across the River Ribble into Preston, by-passing the city centre via Ring Way, where the A583 from Blackpool converges.

Telford's route has now been converted into a cycleway across Penmaenbach and Penmaenan Points. Originally at the western end (Llanfairfechan) of the modern Pen-y-Clip tunnel, access was only allowed in an easterly direction because travelling the other way would mean heading the wrong way up the eastbound carriageway. However, in 2011 a purpose-built bridge - over the westbound carriageway - was constructed to allow unrestricted access to cyclists and walkers. The 1930s alignment was used until a new two-lane Penmaenbach Tunnel opened in 1989 to carry westbound traffic.

The A71 remains as a dual-carriageway until its terminus in Irvine town centre. A crash barrier runs along the central reservation of the dual-carriageway from the A77 to the boundary with North Ayrshire at Dreghorn. In mid 2014, the road began to subside between Darvel and Newmilns, with the westbound lane being affected near to the entrance to Gowanbank House. Traffic lights were put in place while a solution was sought, however as of January 2017, a solution has been found and the traffic lights have been lifted.

In 2017 a group of state representatives met to discuss the possibility of expanding the rest of the route especially from the Brainerd- Lakes area to Cass Lake to a four-lane dual carriageway. They cited safety and a faster travel time as their reasons to do so. As of July 2020, no legislation has been passed to convert the rest of the route to a dual carriageway, however, in 2019 there was an open house for local residents to voice the options about upgrading some junctions on the road.

In the early 2000s, both the continuation from Oldenberg in Holstein to the north and the gap closure in the Eifel between Blankenheim and Daun were planned and partially realized. On 20 December 2002 the section from the former motorway south to north of Oldenberg in Holstein was cleared by the construction of second carriageway. As part of the completion of second carriageway, was the previous B 207 on 21 August 2005 to Gremersdorf upgraded to the highway. Since 25 August 2008, the A 1 ended at the junction Heiligenhafen-Mitte.

It becomes dual-carriageway on the northern outskirts of Leicester and passes the National Space Centre in Belgrave as Abbey Lane. Later, it meets a roundabout with the A563 outer ring-road entering the borough of Charnwood. North of Leicester, as Loughborough Road, it meets the A46 Leicester Western Bypass just south of Rothley and the start of the four-mile (6.4 km) dual-carriageway Quorn-Mountsorrel Bypass. The road at this point follows the Soar Valley, and is mostly on embankment or viaduct, crossing the river four times.

Along this stretch it also passes Salford Crescent railway station near the junction with Albion Way. It then continues as the dual carriageway Broad Street through Pendleton and past the junction with Langworthy Road (A5186). At Irlams o' th' Height it departs from the dual carriageway (where the A580 East Lancashire Road begins) at the old Irlams o' th' Height – Pendlebury (roundabout) boundary. Beyond the Height roundabout it becomes Manchester Road through Pendlebury for a short distance passing both the site of the former Royal Manchester Children's Hospital and Hospital Road.

After this section the road continues to run through the northern fringes of Nuneaton and then on to Tamworth. At Tamworth, the road follows a more recent dual carriageway bypass, permitting the original alignment to become a local road in the town. From this point the road is a grade separated dual carriageway up until its junction with the A38 and M6 toll. After this junction it passes just to the south of Cannock and then enters Telford, where it loses its identity and route-shares with the M54 motorway from junction 5.

At junction 7 the motorway ends and the A5 continues to Shrewsbury as dual carriageway, on its new alignment. (The original route through Telford, and then via Atcham to Shrewsbury, is unclassified through Oakengates and as the B5061 through Wellington and the B4380 through Atcham). Continuing from the end of the M54, the route runs around Shrewsbury as the town's southern bypass (still as dual carriageway), combining for a stretch with the A49. (The route once ran through the town, but was first bypassed in the 1930s, then by-passed again in the early 1990s).

It was the first large box girder bridge to be built to the Merrison Rules, which were introduced in 1973 after the collapse during construction of three box girder bridges during the 1970s. The bridge was strengthened during the 2000s to cope with modern traffic loadings. The bridge spans the river, the Dundee-Perth railway line, a number of warehouses and the A85 high above the surrounding plain. It is a two-lane dual carriageway; unusually for a motorway (although not unusually for the M90) neither carriageway has a hard shoulder.

The road starts as dual carriageway from junction 51 with the A14 road; it then travels north to its junction with the A1120. It then continues to the Suffolk countryside providing access to the villages of Little Stonham, Mendlesham and Mendlesham Green. It passes through Brockford Street (where it crosses the River Dove), Thwaite, Stoke Ash, Thornham Parva, Yaxley and Brome where it meets its junction with the B1077. later it reaches a roundabout with the A143 - where it enters Norfolk and becomes dual carriageway - and a second outside Scole links it with the A1066.

Between 2004 and 2006, the missing, northern (now westbound) carriageway was completed on its whole lengthTable listing highways under construction in Poland, from Nowe Drogi magazine website and most of the overpasses and bridges were reconstructed. By June 2007, the road had two carriageways in use. However, the older of the two (carrying eastbound traffic towards Wrocław) is in a very poor shape, as it still has a surface made of concrete slabs laid in the 1930s. Due to poor road conditions, the speed on that carriageway is limited to 70 km/h.

County Kildare houses the hub of Ireland's network of major roads. The N4 (M4) from Dublin to Sligo travels along the north of the county by-passing the towns of Leixlip, Maynooth and Kilcock. The M7 from Dublin to Limerick runs through the county and by-passes the towns of Naas, Newbridge, Kildare and Monasterevin. This road is colloquially referred to as the "Naas Dual carriageway" because when it was originally up-graded in 1964 the road from Dublin to Naas was a double-lane carriageway, one of the first of its kind in Ireland.

Next, it becomes Bow Road, passing Bow Road Underground station and Bow Church DLR station. There is a dual carriageway flyover over the Bow Interchange roundabout, a junction with the A12. However, at the end of the flyover, the A11 crosses into the London Borough of Newham and becomes a western extension to the A118. Following the opening of the A12 extension in 1999, the A11 was re-numbered to make it seem a less important road and encourage traffic to use the new dual carriageway between there and Leytonstone.

The dual carriageway portion of the Sundale Bridge at night, 2015 The dual carriageway comprising two mirrored sets of eleven concrete piers together with a concrete deck each that carries vehicular traffic was opened in 1966. The decks carried what was then known as the Pacific Highway and is now known as the Gold Coast Highway. In addition to vehicular traffic, a narrow pedestrian footpath formed part of the dual deck structure. In 2010 a separate set of eleven concrete piers were sited upriver adjacent to the most westerly of the existing two decks.

Leger Way in Doncaster next to Doncaster Racecourse The A18 begins as a dual-carriageway and trunk road at the Balby Flyover junction with the A630 in Balby in Doncaster, under which runs the East Coast Main Line. It meets the A638 (former Great North Road) at the Sidings Roundabout then becomes Carr House Road, overlapping the A638. At the Racecourse Roundabout in Belle Vue, the A638 exits to the right (former Great North Road), and the road becomes Leger Way. Near Intake, it becomes a single carriageway and continues to Scunthorpe.

It meets the B1211 and heads to the right as Barton Street (a Roman road). Near Riby, the road becomes a trunk road (until its terminus) then a dual-carriageway close to where it enters North East Lincolnshire. Approaching Laceby on one of the few dual carriageway sections on the Barton Street Roman road The road meets the A46 Grimsby road, and heads straight on over the roundabout. The A18 used to continue eastwards from here along the present A46 into Grimsby, and now continues southwards over Welbeck Hill along the former B1431.

The road has Trunk Road status between Pevensey and Brenzett (A2070) and formed part of the formerly designated South Coast Trunk Road. This section of A259 is almost entirely single-carriageway, with only a short stretch of urban dual carriageway in Bexhill. Landmarks on the A259 include the Butlins South Coast World in Bognor Regis, Shoreham Power Station, West Pier and the Palace Pier in Brighton, Telscombe Cliffs near Peacehaven and Saltdean, Cuckmere Haven between Seaford and Eastbourne and Romney, Hythe and Dymchurch Railway, which shares the route for from New Romney to Hythe.

This section is a modern, wide single carriageway trunk road (which was de-trunked in 2002), apart from the stretch between Tiverton and the M5, which is dual carriageway. Tiverton Parkway railway station is situated close to the junction with the motorway in order to give easy rail connections for people driving from north Devon. Some sections of road are on the alignment of the Devon and Somerset Railway, including the Castle Hill Viaduct over the River Bray, where the stone pillars formerly used to support a lattice girder railway bridge now support the road.

In other locations the new road deviates from the original by many kilometres. In Victoria, 100% of the Hume Highway has been upgraded to at least dual carriageway standard and is called the Hume Freeway. In New South Wales, 97% of the highway has been upgraded to at least dual carriageway standard, with the Hume called the Hume Highway between and , and called the Hume Motorway between Berrima and , being a freeway-grade road. In metropolitan Sydney, the road reverts to the Hume Highway and takes on the conditions of an urban highway.

The road partly or fully follows the former Erewash Valley line The road then reverts to a single carriageway at the Derbyshire border, going underneath the junction with the A608, entering Amber Valley. The road then bypasses Langley Mill to the south, and passes the junction 26 industrial park due to open summer 2019. The A610 then enters Woodlinkin, this particular stretch of the A610 has gained notoriety in the past for road accidents due to the road being particularly windy. The single carriageway Langley Mill By-Pass opened in the early 1980s.

The eastern end of the road is at Bromham on the outskirts of Bedford, where it branches off the A428. Its route then crosses into the Borough of Milton Keynes. It briefly merges with the A509 to bypass Newport Pagnell. Passing over the M1, it crosses through the northern part of Milton Keynes as a dual carriageway, known locally additionally as the H3 Monks Way. Upon meeting the A5 in Milton Keynes, the A422 multiplexes northbound with it for as far as Old Stratford in Northamptonshire where it regains its identity (and single carriageway status).

After this the road was extended to its current terminus at Morshead Drive, although the northbound carriageway was originally routed over Dairy Flat Road until a southbound carriageway was constructed later on. Further duplication was performed to other sections of the extension until all sections were completed in mid-2012. The northern end of the Monaro Highway now connects to the southern end of the Majura Parkway following the latters completion in 2016. Territory and Municipal Services has classified the Monaro Highway as an arterial road within the ACT Road Hierarchy.

The A518 is a road in the United Kingdom which runs from Uttoxeter, Staffordshire to Telford, Shropshire via Stafford and Newport. Between Uttoxeter and Stafford it is a single carriageway, with a staggered junction with the dual carriageway A51. Entering Stafford from the east, it passes through the former Stafford Beaconside campus of Staffordshire University before hitting a roundabout with the A513, which at this point is named 'Beaconside'. It then heads into Stafford as 'Weston Road', passing around the town centre and heading out along 'Newport Road' and under the M6 motorway towards Telford.

For older systems, this may refer to horsecar service for those systems continuously in operation since their horsecar era. ; Stations: The number of stations in the network, as quoted by the system's operator. ; System length: The system length of a tram/streetcar or light rail network is the sum of the lengths of all routes in the rail network in kilometers (or miles). Each section of track is counted only once, regardless of how many lines pass over it, and regardless of whether it is single-track or multi-track, single carriageway or dual carriageway.

The village of Loughlinstown grew up on commonage land on the Dublin to Bray high road. During the 1960s, one of the earliest stretches of dual carriageway in Ireland was built through the area, leaving the village scattered along the western side of the new road. For years a large mature chestnut tree was located in the middle of the dual carriageway at its junction with the Wyatville Road. It was known as The Big Tree and was a landmark feature on the road from Dublin to Wicklow.

The initial section of the E20 from Shannon Airport to Dublin via Limerick is approximately 228 km long and is only partially signed, along the M7/N7. The section from Shannon Airport to east of Limerick is mainly dual carriageway, with a short section of motorway as part of the Limerick Southern Ring Road. The Shannon Tunnel, opened on 16 July 2010, completed the bypass of Limerick. The section from Limerick to Naas is motorway (M7), and the final section from Naas to Dublin is dual carriageway (N7).

The road's function as a primary transport corridor dates from Edinburgh's post war Abercrombie Plan which proposed York Place and Queen Street as a dual carriageway. This was to then go under the Moray Estate in a tunnel. The one piece which was completed was the huge Picardy Place roundabout, which was to link to a tunnel through Calton Hill reached by a huge bridge over Greenside, leading to a further dual carriageway on the Pleasance. The previous narrow streets in the Picardy area acted as a natural traffic restrictor.

As of July 2019 the N11/M11 is of dual carriageway or motorway standard from Dublin as far as Oilgate in County Wexford. The road is a busy commuter route, being the only dual carriageway passing through the south eastern suburbs of Dublin, as well as close to the many commuter towns along the east coast as far south as Gorey. Summer Friday and Sunday evenings also see very heavy traffic as Dubliners decamp to and return from their many holiday home locations along the Co. Wicklow and Co. Wexford coastlines.

West of Bray in County Wicklow, the motorway ends, with the N11 continuing south as dual carriageway through the Glen of the Downs. The upgrading of the road to dual carriageway through the Glen of the Downs was controversial, as the valley is a wooded area. Expanding the road resulted in the removal of some woodland. A campaign of protests, mainly by environmental activists, led to long delays in the construction of this section of road, but the work was eventually completed with a minimal disruption to the woodland.

Most of the road between Swindon and Oxford, apart from the dual carriageway sections and a short section around Faringdon, is limited to 50 mph (80 km/h). A further dual-carriageway section bypasses Cumnor Hill, to give a view of the "City of Dreaming Spires" that is Oxford from the west. It then passes the Oxford Ring Road, through the suburb of Botley and down the Botley Road. It crosses the River Thames on Osney Bridge and reaches central Oxford after passing under the Cherwell Valley Line next to Oxford station.

Until the early 1970s, the road ran from a junction with the A57 road at Bold Heath, four miles west of Warrington. The road currently begins at junction 7 (Rainhill Stoops) of the M62 motorway in Merseyside, and runs in a northerly direction as a dual carriageway through the centre of St Helens, meeting the A58 road, then the A580 road to the north of the town. The road continues in a north-westerly direction, bypassing Rainford to dual carriageway standard. It crosses the border into Lancashire, before reaching junction 3 of the M58 motorway.

Phase 2 encompasses the contraflow between Junctions 8 & 9 on the M20 and now applies to HGVs for both the Port of Dover and Channel Tunnel. Both directions of motorway traffic are directed onto the westbound carriageway contraflow at a speed limit of 50 mph. The eastbound carriageway will then be closed and used for HGV queuing in two lanes (the hard shoulder and 3rd lane) with the other two lanes are reserved for emergency vehicles, maintenance vehicles and amenities. This would be marked out with cones and subjected to a 30 mph speed limit.

The national road from Sofia to Vidin (I-1/E79) is linked to the Hemus motorway (A2) up to the city of Botevgrad, and continues with a dual carriageway road to Vratsa. The road from Montana to Vidin is a rehabilitated two-lane single carriageway road. There is also another road from Sofia to Vidin (81), via Kostinbrod and through the Petrohan Pass to Montana. This road is shorter and very scenic, but it takes more time as it runs over the Balkan Mountains and through the villages.

Beginning at the historical and now bypassed Great Eastern Highway in South Guildford, the road passes through a light industrial area, and meets the Great Eastern Highway Bypass, which provides access to Perth City and Midland. It then passes by Perth Airport and Guildford Cemetery, before passing through the foothills suburbs of High Wycombe and Maida Vale. After meeting Roe Highway, it is allocated State Route 41, and is dual carriageway for this section between the highway and Hawtin Road. It then reverts to single carriageway and ascends the Darling Scarp.

The A590 is a trunk road in southern Cumbria, in the north-west of England. It runs north-east to south-west from M6 junction 36, through the towns of Ulverston and Barrow-in-Furness to terminate at Biggar Bank on Walney Island.A590: M6 J36 (Crooklands) - Walney Island SABRE; Accessed 07-05-08 The road is a mixture of dual carriageway and single carriageway, with the section east of Low Newton, Cumbria to the M6 being mainly dual. Further dual sections are south of Newby Bridge, south of Greenodd and south of Ulverston.

The valley has a railway as far as Bourg-Saint- Maurice, which, in the winter season, has various direct sleeper trains from Paris and Eurostar trains from London. The valley road (the N90) is dual carriageway as far as Moûtiers, after which it becomes a standard two-lane but single-carriageway road, which can see substantial queues in winter. This road is currently receiving funding from the European Union for a significant improvement project between Aime and Moûtiers, one of the narrowest points in the valley. Costume of Tarentaise Valley, in 1919.

A344 junction with the A303 by Stonehenge was closed and returned to nature. The most controversial upgrade of the A303 has been improvement to the road through the Stonehenge World Heritage Site, where it remains a congested single carriageway road. There were minor improvements in the 1960s, including closing the road for a month in 1967 for levelling and resurfacing. A proposal to fully dual the A303 past Stonehenge was announced in the mid-1970s, but was criticised as being "an environmental disaster" and comparable to driving a dual carriageway through Westminster Abbey.

The M25 Junction 10 is 4 miles away and an A-roads and dual carriageway connect neighbouring (but not contiguous) Esher and the almost bordering towns of Weybridge and Cobham, across a narrow strip of Walton on Thames.

Jalan Gasing is a major road in Petaling Jaya city, Selangor, Malaysia. It is the first dual-carriageway road built in Malaysia since independence. It also has the most number or churches in a single street in Malaysia.

Until the A24 dual carriageway was built, the distinction between the original Beare Green and the area around Holmwood Station that is now also known as Beare Green was not distinct, as the turnpike road ran through both.

"Anti-US and anti-Băsescu protests at the University. CCR decision drew hundreds of people in the street", Ziare.com Spirits were engirt and, at around 9:00 p.m., people breached fences and entered on the carriageway, blocking traffic.

During construction of the end box girder bridges, the traffic had to be diverted round the supporting scaffolding. This was especially inconvenient on the outbound carriageway of the N1 where speed was severely reduced, adding heavily to congestion.

The A278 was formerly used as the number for the Felbridge - Horsham road, which is now part of the A264. However, the A278 is now used for the long dual carriageway that links the M2 to the A2.

Evidence of this unbuilt alignment remains in the wide gap between the carriageways to the east of the South Mimms junction which would have been the point at which the spur would have separated from the continuing carriageway.

Carmarthen Road is a dual carriageway stretch of the A483 which runs NW from the Dyfatty traffic junction in the city centre. Carmarthen Road has a mix of developments including residential, retail and commercial parks and industrial units.

While substantial internal alterations were carried out on the building in 1964, both the structure and the facade remain intact. The timber framing, floor joists and herringbone strutting are evident on the underside of the first floor carriageway.

This carries the A61 dual carriageway across the River Don. This part of the A61, which fronts the football ground, was widened in time for the 1966 World Cup matches and still features the flagpoles for the event.

The Inner Distribution Road or IDR is a mostly dual carriageway ring road that encircles the town centre of Reading, Berkshire, England. It forms part of the A329 that runs from Wentworth in Surrey to Thame in Oxfordshire.

Junctions 8 and 10 of the M65 are both some from the town centre. Junction 8 of the M65 also gives access to the A56 dual carriageway leading to the M66 and access to the Manchester motorway network.

Because of this work, Burns Beach Road was turned into a dual- carriageway from Joondalup Drive to Marmion Avenue. In 2017, Mitchell Freeway was extended to Hester Avenue, thus making a diamond interchange at what was the intersection.

Greek National Road 33 (, abbreviated as EO33) is a single carriageway road in southern Greece. It connects Patras with the Greek National Road 74 (Pyrgos - Tripoli) near Levidi, passing through the western and southern foothills of Mount Erymanthos.

From the A2 dual carriageway near Gravesend, take the A227 towards Wrotham. Pass through the village of Meopham and turn left into Green Lane and turn right into Camer Park Road. It has a free entry car park.

Jalan Bukit Katil or Jalan Tun Kudu (Malacca state route M144) is a dual- carriageway state roads in Malacca state, Malaysia. It is also a main road to North–South Expressway Southern Route via 143 Lebuh Ayer Keroh.

Between Worcester and Birmingham the current A38 follows the line of a Saxon salt road;Taylor (1979), page 96. For most of the length of the M5 motorway, the A38 road runs alongside it as a single carriageway road.

As soon as these lanes became operational, another carriageway will be built. The government shoulders the financing for the construction, but upon completion, the operation and maintenance of toll facility will be offered to the private sector through concession.

For this reason, SS4 had once a rather rough course from here on, with tight bends and continuous rises and descents; current SS4 is a completely new road (constructed in the 1960s to replace the old one from Passo Corese to Rieti), much more straight and wide, albeit still with a single carriageway. The , dual carriageway road tunnel "Colle Giardino", near Rieti As the road passes the Sabine mountains, it reaches an altitude of 400 metres above sea level at Osteria Nuova and it descents into a narrow valley, then rises again until reaching 570 metres in the village of Ornaro, and finally descents. south of province capital Rieti the road becomes a dual carriageway road; the long "Colle Giardino" road tunnel allows the road to leave Sabine mountains behind and to enter the Rieti plain (400 metres on sea level) where the city is settled.

Ocean Reef Road commences at the intersection of the southern and eastern legs of Gnangara Road and Sydney Road in Landsdale, with Ocean Reef Road continuous with the eastern leg of Gnangara Road, and terminates at the roundabout with Shenton Avenue in Ocean Reef, continuing northwards as Burns Beach Road. The road is a four-lane dual carriageway for almost its entire length, with the exception of the northwards parts running parallel with the coast, where the road is a two-lane single carriageway between Swanson Way and Hodges Drive, though it widens to a two-lane divided carriageway for the remainder of its length. It predominantly carries an speed limit, which reduces to at Trappers Drive, and then to from Hodges Drives to its northwestern terminus. The entire length of the road forms part of State Route 84, along with the eastern section of Gnangara Road.

The highway began as a trunk road. It was later widened into six lane dual-carriageway, and upgraded during the 1980s. The section between Johor Jaya to Ulu Tiram were upgraded in 1995. Traffic is usually heavy during working hours.

The road begins at the Porte de Saint Cloud, southwest of central Paris, as the Avenue du Général Leclerc. It passes the suburb of Boulogne-Billancourt. The road crosses the river Seine. Through traffic then takes the RN 118 dual carriageway.

Delhi firm bags Rs 190 cr NHAI road contract. Business Standard (2006-01-11). Retrieved on 2013-12-06. The work included four laning of the existing two-lane carriageway on the Raipur-Bhilai section of NH-6 in Chhattisgarh.

The M32 is an overwhelming barrier to mobility and accessibility for residents of St Pauls and Easton, with the main links between the areas consisting of grade-separated dual carriageway intersections and narrow footbridges crossing the motorway at a dizzying height.

Approaching Mickleover, it becomes a dual-carriageway. Passing the Mickleover Court Hotel, the road enters the City of Derby. The road used to pass through Mickleover, which is now the B5020. The £5.2m Mickleover bypass opened on 19 February 1975.

Road and rail may share the same carriageway so that road traffic must stop when the trains operate (like a level crossing), or operate together like a tram in a street (street running). Road–rail bridges are sometimes called combined bridges.

As of 2010, the entire freeway from Mooloolaba to Pacific Paradise is four lane dual-carriageway motorway. There is still a two-lane section between Kawana Way and Nicklin Way, and north of Pacific Paradise is also still two lanes.

Ralston (Baile Raghnaill in Scottish Gaelic) is a small, suburban settlement in Renfrewshire, Scotland, being part of the greater town of Paisley. The district straddles the A761 (formerly the A737), the main dual-carriageway between Renfrewshire and the City of Glasgow.

The most heavily used dual carriageway in Croatia is the B28 expressway, connecting capital Zagreb to a satellite town, Vrbovec. The D28 is currently finished up to the Gradec interchange. It is undergoing extensions which will increase the traffic traversing it.

The A52, 'Borrowash by-pass' recently named Brian Clough Way, cuts through the village and provides express road (dual-carriageway) links to the west (Derby) and the east (M1 and Nottingham). Regional Cycle Route 66 links Spondon to Chaddesden and Alvaston.

The road passes north of St Pancras and Islington Cemetery towards Friern Barnet and Muswell Hill. The road narrows to two lane single carriageway to pass under the East Coast Main Line, and continues as Telford Road towards Bounds Green.

Greek National Road 1 (, abbreviated as EO1) is the old single carriageway road connecting Athens with Thessaloniki and Evzonoi, the border crossing between Greece and North Macedonia. For most of its length, it has been replaced by the new A1 motorway.

Near Tilney All Saints, it meets the old route at a roundabout, becoming the single carriageway Main Road, then Pullover Road. It meets the end of the A17 at the “Pullover Roundabout” where the West Lynn Little Chef is located.

The roundabout also marks the start of the Dearne Valley Parkway, a relatively new dual carriageway which links the M1 at Junction 36 to the A1 at Marr (near Doncaster). Birdwell is run under the auspices of Barnsley Metropolitan Borough Council.

R133 dual carriageway on Drummartin Link Road The R133 road is a regional road in south Dublin, Ireland. The road starts at Goatstown and runs in a southerly direction towards Sandyford before acting as a link road for the M50.

Suspending a scaffold from the carriageway was also unsuitable because the bridge could not withstand the kentledge weight required. The chosen solution was for the scaffold to be founded on the river bed with tubes secured around piers providing anchorage.

Contact Us, Cabo Verde Express. Retrieved on 14 August 2018. The national road EN1-SL01, a dual carriageway, connects Espargos with Santa Maria in the south of the island. Other national roads connect it with Pedra de Lume and Palmeira.

Greek National Road 82 (, abbreviated as EO82) is a single carriageway road in southern Greece. It connects Pylos with Sparti via Kalamata. It passes through the regional units Messenia and Laconia, on the Peloponnese peninsula. Its length is 110 km.

After bridging Powis Lane in between Westcroft and Oxley Park the road becomes a dual carriageway at Shenley Roundabout. Subsequently it bridges both the A5 and the WCML railway. The road then crosses the V6 Grafton Street and runs along the southern edge of Central Milton Keynes and Campbell Park before passing Willen Lake. After this it passes the original Milton Keynes village and then curves up to meet the A509, briefly becoming the A4146. The H7 Chaffron Way is one of the longest grid roads but is a single carriageway for the entirety of its route. It starts in the district of Tattenhoe Park where it had a 300-metre extension built in 2007, runs past Westcroft District Centre, Furzton Lake, The National Bowl, bridges the A5 and the West Coast Main Line in one go, passes Woughton before terminating at a roundabout next to Broughton. In March 2010, the route onward (Countess Way) was opened which links to Newport Road (former A5130) in Brooklands, a dual carriageway with a permanent bus lane on each side with traffic lights at either end. H8 Standing Way is a dual carriageway that crosses MK from west to east, co-designated as the A421.

Up until this point the A6 runs parallel with the M2 and M22 motorways, which since their construction in the 1960s/1970s have removed the vast bulk of the cross-country traffic from the A6. A mile west of Randalstown the A6 meets with the M22 motorway at Randalstown West junction (a non-motorway junction), and from this point onwards the A6 carries traffic bound for Mid Ulster and the North West. For 46 years from 1973 to 2019, the A6 ran for 4.1 miles along the Moneynick Road which has many twists and turns, making it difficult for traffic to safely pass slower moving vehicles; this part of the former A6 witnessed a high number of collisions, many fatal. A new offline dual carriageway opened on 4 August 2019 from Randalstown West junction to the start of the Toome Bypass dual carriageway and became the A6, A6 Randalstown Castledawson Dualling scheme the Moneynick Road being re-classified as the B183. On the Toome Bypass, the A6 crosses the River Bann between Lough Neagh and Lough Beg to enter County Londonderry. 2.2 miles after it starts, the dual carriageway narrows and reverts to standard single carriageway, through Creagh and onto the Castledawson Bypass and crosses the Moyola River.

The road commences at junction 8 on the M6 east of Athlone and continues for a short distance as dual carriageway forming a short section of the Athlone bypass. Following the roundabout junction with the R446 towards Athlone town, the road is single carriageway two-lane throughout. The route passes through towns such as Ferbane, Birr, Roscrea, Templemore and Thurles and has not bypassed any of the towns and villages along its route. The quality of the surface, pavement and alignment varies, but it has no stretch of fully realigned 'two-lane with hard shoulders' section.

Sofia Northern Bypass The Northern Bypass Highway (, ) or Sofia Northern Speed Tangent is a dual carriageway, grade separated road with controlled-access, designed for high speeds. The bypass has three traffic lanes and an emergency lane in each carriageway. It bypasses the Bulgarian capital Sofia from north with the purpose to carry the transit traffic, which otherwise has to pass through the city or via the Sofia ring road. The bypass is an important thoroughfare, as it connects four motorways - A1 Trakia motorway (via the Sofia ring road), A2 Hemus motorway and the A3 Struma motorway.

A tunnel starting just west of the Schuman roundabout takes the main carriageway of Rue de la Loi under the Cinquantenaire (with a short uncovered section in the centre of the park), and emerging at Merode as the central carriageway of Avenue de Tervueren. The avenue was commissioned by King Leopold II of Belgium as part of his building campaign, and finished in 1897 in time for the Brussels International Exhibition of that year. Tram route 44 follows a large portion of Avenue de Tervueren, from Montgomery station all the way to Tervuren. For much of the distance, it has a dedicated track.

Eltham High Street lies on the A210, the original A20 London to Maidstone road. But the A20 has now been diverted southwards, passing through Mottingham, and it is a dual carriageway that connects to the M20 motorway in Kent. Similarly, to the north, the dual carriageway A2 has replaced the Rochester Road section, which was always very congested (the old road had dangerous readings of lead pollution, close to schools, before the advent of lead-free petrol). The upgrading of these two arterial routes in and out of London means that Eltham is handily positioned between the A20 and A2.

The southern carriageway would have passed the Sri Petaling and Bukit Bintang Boys School, and run elevated above Jalan Utara. An off ramp would have fed the traffic destined for the Federal Highway, Petaling Jaya State or University Hospital into Jalan Utara, before the Ehsan Ria Condominium. The elevated road would have continued past Amcorp Mall and around PJ State until rejoining the northern carriageway near the Section 8 police station. From Section 8 PJ the proposed highway headed south through Section 4 and Old Town PJ south, crossing the NPE and KESAS highways before ending at Bandar Kinrara 2.

An Agusta 109E as used by HEMS (Helicopter Emergency Medical Service) A chapter of You Can't Park There! describes Bleetman's Heli-Med team making a landing on a busy carriageway of the M1 motorway to attend a multiple vehicle accident scene. The dramatic manoeuvre, in which the Heli-med crew's Agusta helicopter taxis between the motorway traffic, was captured on film by a stationary motorist in the halted vehicles on the opposite carriageway of the M1. The book recounts what was thought at the time to be the controversial nature of the landing because of the aircraft and vehicle proximity.

Autopistas in Gran Canaria provide rapid road transport around the coast A Gran Canaria bus Gran Canaria Airport The Tenerife catamaran ferry Gran Canaria has roads encircling the whole island and extending into the mountain areas. In the late 20th century, its dual carriageway, among the first in the Canary Islands, were opened and run around Las Palmas de Gran Canaria, and were later extended to the north coast and the airport and subsequently to the south coast in response to increased tourist traffic. The only highway of Gran Canaria are GC1. Dual carriageway is GC2, and GC31, GC4 and GC5.

Engineering consultants Faber Maunsell began work on the project in 2006; it took two and a half years to complete at a cost of £7.8 million. As part of the works, some of the corroded cable strands were spliced. The southbound carriageway of the bridge was closed on 1 December 2015, with all traffic using a single lane each way on the northbound carriageway after steelwork defects had been discovered during routine inspections, and traffic was restricted to 7.5 tonnes or less (public service vehicles excepted). On 4 December, the bridge was fully closed when further structural faults were found.

The road continues for another brief spell as a 40-mile-per-hour dual carriageway passing the Springhall and Whitlawburn housing schemes. Soon afterwards the road drops to a 30-mile-per-hour zone and the dual carriageway section ends at a junction with the A730 road at Burnside railway station. Turning right onto Stonelaw Road through the Burnside district the road continues down to Rutherglen town centre, meeting the historic Main Street at Rutherglen Cross. It crosses over the West Coast Main Line railway beside Rutherglen railway station, and under the M74 motorway (however offers no access).

The stated reason for this change is to remove all the traffic which enters the freeway at North Sydney, then exits again at Military Road, adding to peak hour delays. The carriageway change over process was automated around 1990, with moveable barriers and overhead signage directing traffic onto the correct lanes. The changeover occurs when the Harbour Bridge needs either 5 or 6 lanes southbound (the default is 4 each way). There is only ever a maximum of 5 lanes northbound off the bridge, with the extra lane feeding into a spare lane on the inner west carriageway.

The Car Dyke lies to the east and the boundary between Elsea Wood and Math Wood seems to lie along the edge of the 2nd century road verge, which was cleared for security. The carriageway, the Car Dyke and the Math Wood boundary are all parallel here. When allowance is made for the now-missing outer works of the Car Dyke, the carriageway lies halfway between the other two features. North of Bourne, little of the road is still in use but it has left its mark in the form of property boundaries and soil marks.

River Itchen, Bitterne Manor The area is bounded on the north, west and south by the River Itchen, and on the east by the railway line linking Southampton to Portsmouth. Northam Bridge crosses the river to the neighbouring suburb of Northam, whilst beyond the railway line is the suburb of Bitterne. The A3024 dual carriageway runs through the area, one of the primary commuter routes in and out of Southampton from the East. Apart from the grounds of the manor house, the area immediately around the dual carriageway is mostly taken up by residential housing and Bitterne Manor Primary School.

Penn Inn roundabout - northern approach The Penn Inn Roundabout is a signal-controlled roundabout interchange at Newton Abbot where the A380 used to meet the A381 and an unclassified road at one of the busiest roundabouts in Devon. The A380 now continues over the roundabout on a single carriageway flyover continuing to Exeter as part of the South Devon Highway (Traffic can still get to the roundabout off the dual carriageway using the other lane). This is to relieve congestion especially at peak times. There is a completely separate system of subways for pedestrians underneath the roundabout.

Starting at the junction of the A45 and A46 at Festival Island west of Baginton just south of Coventry, the road runs as a dual-carriageway one mile north to the Whitley junction. Here there is a break in the road and it starts again at the roundabout where the A428 Sky Blue Way/Binley Road and the B4110 Humber Road meet in Gosford Green just east of Coventry. From there it heads north as a dual-carriageway road, crossing the M6 at junction 3. It bypasses Bedworth to the west and heads into Nuneaton passing the George Eliot Hospital.

The PDR is dual carriageway for its entire length except for Rover Way and the East Moors Viaduct, which is a single carriageway. The entire length of the road has clearway restrictions on it. The PDR has been constructed in separate link roads of between and around Cardiff and to date including spurs have been opened to traffic, with plans for a further . It has 5 large viaducts (Ely Viaduct, Grangetown Viaduct, Taff Viaduct, Eastern Bay Link Viaduct and the East Moors Viaduct), 1 tunnel (Queen's Gate Tunnel) and 2 spur roads (Cogan Spur and Central Link Road).

The highway was upgraded from single carriageway to dual carriageway in the 1980s. In 1995, the highway was taken over by the Metramac Corporation Sdn Bhd which also managed the Cheras Highway (Federal Route J1), East–West Link Expressway and Kuala Lumpur–Seremban Expressway (both E37). The Jalan Pahang toll plaza (city centre bound) was in operation from 1 August 1995 and the motorist would pay the RM 0.50 tolls until the toll plaza was abolished 13 August 2004. This highway is now maintained by the Kuala Lumpur City Hall or Dewan Bandaraya Kuala Lumpur (DBKL).

It initially joined all the major coastal centres; however, a number of bypasses, particularly in the south, have diverted traffic around these cities to expedite traffic flow and ease urban congestion. As a result, the highway is constantly being shortened. The road is a dual carriageway from Brisbane to Kybong with some dual carriageway lengths at Gympie, many of these upgrades being completed in the 1980s (Glass House Mountains, Tanawha, Maryborough) and 1990s (Nambour, Yandina, and Cooroy). The highway commences just south of the bridge over the Pine River at the Gateway Motorway interchange, north of the Brisbane central business district.

From the M4 to Cirencester it is a dual carriageway road, which generally follows the course of the Roman road Ermin Way, but dualling work completed in the late 1990s, and the bypass of Cirencester, has taken it off-course in some places. East of Cirencester the A417 continues straight ahead as the major road and the A419 separates through Cirencester and Stroud, becoming mainly single carriageway. West of Cirencester the road loses its primary status; it crosses the M5 at junction 13 close to a former Little Chef restaurant, then finishes further west at a roundabout with the A38.

The freeway upgrade has made sections of the original Goulburn Valley Highway redundant, either incorporated into the new freeway or acting as local access roads. The freeway section is covered with a speed limit of 110 km/h, the standard speed limit for rural freeways in Australia. Between Arcadia and Tocumwal the highway is a two lane single carriageway but with tactile road lines, wide shoulders and small sections of 3 or 4 lane single carriageway road for overtaking. The Goulburn Valley Highway crosses the Murray River at Tocumwal to join the Newell Highway in New South Wales.

The N4 West Platinum Highway toll route (west of Pretoria) is currently operated by the Bakwena consortium under license from the South African National Roads Agency Limited (SANRAL). Bakwena is in the process of adding a second carriageway to the N4 between Brits and Rustenburg which would also widen the roadway to four lanes. As of December 2019, the upgrade between Brits and Rosslyn is being constructed, which creates a continuous four-lane dual-carriageway toll freeway from Rustenburg to Pretoria. The N4 East toll route (east of Pretoria) is currently operated by Trans African Concessions (TRAC) under license from SANRAL.

Due to the 1973 oil crisis, a temporary maximum national speed limit of for all roads, including motorways, was introduced on 8 December 1973. The limit was restored on motorways in March 1974 and on all other roads on 8 May 1974. As an initiative to reduce energy consumption, the national speed limits for otherwise unrestricted single-carriageway and dual-carriageway roads were temporarily reduced to and respectively (motorway speed limits were left unchanged at ) from 14 December 1974. In November 1976 the temporary speed limits were extended at least until the end of May 1977.

After leaving the roundabout the road is two-lane dual carriageway with a speed limit for approximately . A further roundabout with Trent Street by a call centre for Virgin Media sees a change to 2 lane single carriageway, as it is for the remainder of its length, retaining the limit. After a further roundabout at Nottingham Racecourse, the limit changes to the national speed limit of until Colwick is reached, when it changes to to pass through a built up stretch. Leaving Colwick the road becomes the Colwick Loop Road, which bypasses Netherfield, Carlton and Gedling.

The N6 road is a national primary road in Ireland from junction 11 on the M4 motorway at Kinnegad to Galway city. The N6 and N4 form a continuous motorway or dual carriageway from Dublin city centre to Galway City passing in an east–west direction through the midlands of Ireland. Most of the road is motorway standard (designated as M6 motorway) with the exception of the Athlone bypass and stretches of urban road in Galway City, which are the only sections of the road that remain designated as N6 dual carriageway. There is one toll on the road outside Galway city.

It then continues to climb, crossing the long Malakoff Bridge and passing through the long Lämmerbuckel Tunnel before rejoining the other carriageway at Hohenstadt. The northbound carriageway, long, passes through the long Nasenfels Tunnel and skirts the Drackensteiner Hang proper on the long Drachenloch Bridge (named for the 'dragon's cave', sealed off in the building of the motorway, the story of which is presumed to have given the name to the cliffside and the community of Drackenstein),Historie , Gemeinde Drackenstein, 2010 the long Himmelsleiter Bridge and the long Fischerhäusle Bridge before crossing the Fils west of Gosbach.

Sharps Road, which runs east-west near the southern border of Tullamarine, was until the late 1980s a single carriageway road. On its southern side was a line of tall pine trees hiding a small pony club. Today, Sharps Road is a bustling dual-carriageway road providing an alternative route from the Western Ring Road to Melbourne Airport. In 1987 the median house price in Tullamarine was 97% of the median for metropolitan Melbourne, and in 1996 it was 82% of the metropolitan median. Tullamarine had census populations of 82 (1891), 190 (1921) and 204 (1947).

After the end of the Tonbridge bypass, the A21 climbs Castle Hill as the Pembury Bypass as it reaches the North Farm interchange with the flyover for non-stop traffic. The next junction is with the A264 road to Tunbridge Wells and the A228 to Maidstone. The road later meets the original alignment at an at-grade junction (leaving a brief gap in the central reservation) not long before it meets a double roundabout at Kippings Cross where another section of single carriageway starts. The next section of A21 is a major bottleneck, being a single carriageway with frequent bends.

St. Patrick's Bridge The city's road infrastructure improved in the late 20th and early 21st century, including from the early 1980s construction of the Cork South Link dual carriageway which links the Kinsale Road roundabout with the city centre. Shortly after, the first sections of the South Ring dual carriageway were opened. Work continued on extending the N25 South Ring Road through the 1990s, culminating in the opening of the Jack Lynch Tunnel under the River Lee. The Kinsale Road flyover opened in August 2006 to remove a bottleneck for traffic heading to Cork Airport or Killarney.

The first plan for a high-level bridge was a truss bridge with three or five spans, giving an dual carriageway with a cycle track and footpaths. This was abandoned because it was too expensive, and because one of the piers would be too close to the wall of the ship canal. The next idea was for a suspension bridge with a span of between the main towers with an single carriageway and a footpath. However aerodynamic tests on models of the bridge showed that, while the bridge itself would be stable, the presence of the adjacent railway bridge would cause severe oscillation.

East of Wellingborough, the road crosses the Midland Main Line. There is a grade-separated junction for the A5001 into Rushden and the route runs alongside the River Nene, offering a second turning to Rushden at a roundabout with the A5001 again; at this second junction, the original route to the A1 has been reclassified the B645. At the roundabout with the A6 near Higham Ferrers, it starts the follow the former route of the A605. The section of dual carriageway from the M1 now ends at the next roundabout and the route from there is now single carriageway.

As of 2007 there were plans to upgrade the Osijek southern bypass to an expressway by construction of an additional carriageway, especially since all junctions along the section are already grade separated. In September 2011, the expansion construction works were formally opened: The works are scheduled to be completed in 30 months and they comprise an additional carriageway, adaptation of the existing interchanges and construction of a new interchange along the section. The works comprise the D2 section between interchanges with the A5 motorway and the Ž4091 road. Most of the D2 road also runs parallel to railway tracks.

As the Sunshine Coast continues to grow, more and more stress is placed upon the Motorway from the added weight of the population. During peak hours, most interchanges along the single- carriageway section of the Motorway acquire congestion. To remedy this problem, Main Roads Queensland are currently planning and constructing various new sections of the Motorway, under a plan called SM2032. These constructions mainly include upgrading to dual carriageway along the more populated areas through which the motorway passes; other constructions included the Maroochy River Bridge duplication (completed in 2008) and various safety measures throughout the entire length of the motorway.

Joondalup Drive is part of State Route 85. The south-western terminus is Ocean Reef Road in Edgewater and the north-eastern terminus is Old Yanchep Road (formerly Pinjar Road) in Mariginiup, continuing eastwards as Neaves Road to Bullsbrook in the City of Swan. It is a four-lane dual carriageway for most of its length, reducing to a two-lane single carriageway for the remainder of its length east of Tumbleweed Drive and Joseph Banks Boulevard. The speed limit is mostly , though there is a short section at the northern extent of the suburb of Joondalup.

Work on the site started in Autumn 2010 and construction eventually started in mid-2011 on the slip roads and tunnel for the service area. The speed limit was reduced to 50 mph, and a temporary carriageway was set up, diverting traffic past the construction site and back onto the motorway. The 50 mph speed limit took place on a short section of the westbound carriageway, where construction traffic was accessing the site. Extra MSA founded their own construction company called 'Swayfields' immediately when Extra MSA was created in 2000, so they could construct service areas themselves.

Cycle Superhighway 2 (CS2) runs alongside the A11 between Aldgate and the A12 in Bow. One-way cycle tracks run along either side of the A11 through Whitechapel, Mile End, and Bow, carrying cyclists from the City to Stratford. The route runs unbroken; the route is signposted and marked using blue paint and cycle icons. At Bow, where the A11 meets the A12, CS2 leaves the main carriageway along slip roads, and cyclists may congregate at an Advanced Stop Line - in both directions - to cross the roundabout, rejoining the main carriageway on the other side of the roundabout.

The A4214 is a ring-road around Llanelli in Carmarthenshire, west Wales. The route begins at the junction with Hall Street and Gelli-onn, on the A484 road in northwest Llanelli. At this point, the road is a dual-carriageway as it heads south-east along Hall Street to the Public Library, then south-west along Church Street and past the town council, government buildings, then south-east again past the town hall and county council offices. Here, the road turns into a single-carriageway as it becomes Station Road to the junction with the B4303 and Queen Victoria Road.

The route was enhanced by partial clearing when a rough service vehicle track was created in the mid-1950s to assist with the laying out of high voltage power poles and lines, which now follow this road reserve for its full length. The current Panalatinga Road is a four lane dual carriageway for the 4.6 km length north of Wheatsheaf Road, and a two lane single carriageway for the 1 km to the south. The entire road has a speed limit of 80 km/h, and is used as an alternative to South Road and local road States Road.

In 1999 the bridge was closed for around a month to resurface the road and strengthen the structure, requiring all traffic to cross via the nearby Britannia Bridge. On 28 February 2005 the bridge was promoted to UNESCO as a candidate World Heritage Site. On the same day one carriageway of the bridge was closed for six months restricting traffic to a single carriageway so that traffic travelled to the mainland in the morning and to Anglesey in the afternoon. The bridge was re-opened to traffic in both directions on 11 December 2005 after its first major re-painting in 65 years.

At approximately 10:00, the gunman carjacked a first generation Volkswagen Sharan minivan at a car park in Winnenden. From his position on the rear seat, the gunman ordered the driver Igor Wolf to drive towards Wendlingen, from Winnenden. The gunman and the driver went westwards into the suburbs of Stuttgart, the Baden-Württemberg state capital, travelling through the towns and districts of Waiblingen, Fellbach, and Bad Cannstatt, before driving on the B14 dual carriageway through the Heslach Tunnel onto the A81 autobahn motorway towards Böblingen and Tübingen. The two drove onto the B27 dual carriageway before leaving on the B313 to Nürtingen.

As well as a general bypass of Central London, it would connect the communities of Edmonton, Tottenham and Walthamstow, and allow former munitions factories to be reused for industrial purposes. Further west, industrial work increased around Wembley to cater for the 1924 British Empire Exhibition, while former military factories at Willesden, Hendon and Acton would also benefit from being connected by the North Circular Road. The land used for the route was mostly cheap, which encouraged further works and factories to be built by the road. Purpose-built sections were designed to dual carriageway standards, including a wide carriageway accompanied by verges.

At this point, as St Walburga's Road, it continues north, and later becomes dual carriageway for . After the Plymouth Road roundabout, it crosses the railway, and continues north as Bispham Road for a further to Bispham roundabout, where it becomes Devonshire Road and then Fleetwood Road. further on it is joined at Anchorsholme by the A584, the Queen's Promenade, and continues north through Cleveleys for as a dual carriageway, named Fleetwood Road and Kelso Avenue for north and southbound traffic respectively, with the tram tracks dividing the road. It then enters Cleveleys as it enters the Wyre District.

Farther on, the A43 leads to Northampton and the M1. Junction 10 was originally a dumbbell junction. The capacity of both the junction and the single carriageway A43 proved too small when the road was used as a freight thoroughfare from the congested M1 to the M40 to London, and the A34 at J9 to the south coast — in fact the stretch between these junctions is the busiest on the motorway in both directions. When the A43 (between the M1 and M40) was upgraded to dual carriageway, the junction was redesigned and rebuilt by the Highways Agency to cope with the extra traffic.

The single carriageway section of the bypass begins at a roundabout in Templescoby. The road then passes through a roundabout in Milehouse, where it meets the R702, and ends at the Clavass Roundabout, where it meets the R772, just south of the Scarawalsh Roundabout, where the southeastern terminus of the N80 national secondary road is. The dual carriageway section of the bypass then extends in a southeastern direction from the Scarawalsh Roundabout, effectively as a southeastern extension of the N80 road, crossing the River Slaney and connecting to junction 25 of the M11 motorway in Ballydawmore.

Sometimes on dual carriageways, it is necessary to divert one carriageway onto the opposing carriageway, forming a "contraflow". This cannot be done "on the fly", as high-speed (100+km/h), high-volume (500 - 1000+ vehicles per hour) traffic is involved, generating a huge risk to workers. In this case advisory signs will be erected weeks or even months in advance, and new lanes defined by bollards anchored firmly to the road-base will be installed, usually at night when traffic is expected to be minimal. Programmable Variable Message Signs may be utilized at strategic locations to inform motorists.

The A6144(M) was a motorway in Carrington, Greater Manchester, England. It was known in official documentation as the Carrington Spur Road and built to facilitate the transport of hazardous goods from Shell Chemicals' ethylene oxide plant in Carrington and other industrial estates in Carrington and Broadheath. It was unusual in that it was entirely single carriageway, the only motorway of its kind in the UK. The others are dual carriageway for at least some of their length. About 1 mile (2 km) long, the road connected the A6144 road to the M60 at junction 8.

A 12-metre wide pedestrian space will be developed in the 730-metre stretch from Panagal Park to the Thanikachalam Road junction. Upon completion, only city buses and motorcycles will be permitted in this area in a 7-metre carriageway. All types of vehicles will be allowed on the 370-m stretch from Thanikachalam Road to the Boag Road junction, where the pedestrian plaza will be only 3.5 metres wide and carriageway will be comparatively wider measuring 15 metres. All vehicles will be permitted on the 350-metre stretch between the Boag Road junction to the Anna Salai junction.

The road narrows to less than in places and causes significant problems for heavy goods vehicles (HGVs), which have to negotiate tight bends and the narrow carriageway width. At Pulpit rock, the road was single-track, with traffic flow controlled by traffic lights for over 30 years. The road was widened in 2015 as part of a £9 million improvement programme, including a new viaduct bringing the carriageway width to modern standards. The north end of the loch is at Ardlui, after which the A82 continues to follow the Highland Line along Glen Falloch, a typical glacial valley, towards Crianlarich.

The minimum speed limit of 50 km/h, maximum 100 km/h, throughout. Potential speed checks at Zhangjiawan and 500 metres to the east of Yongdingmen/Langfang exit; otherwise, none. It is not rare for passenger cars to zip well in excess of that speed limit, while to see lorries underperform in speed. Southwestern 6th Ring Road: carriageway-separated; note: there are no "overtaking lanes" on this part of the ring road; left lane, maximum speed limit 100 km/h, minimum 80 km/h, designated "car only"; right lane, maximum speed limit 100 km/h, minimum 60 km/h, designated "carriageway".

The road starts on the eastern side of Bodmin at a junction with the A30 before traversing the edge of the town to meet the A30 again. It travels through the picturesque Glynn Valley to Dobwalls and Liskeard, which are bypassed by a dual carriageway. The Dobwalls section contains the most sophisticated bat bridge yet constructed in the UK. The A38 continues through the Cornish countryside, bypassing the centre of Saltash and continuing through the Saltash Tunnel. Immediately after the tunnel the River Tamar is crossed using the Tamar Bridge where the route resumes dual carriageway status.

The Paston Parkway bypasses the eastern edge of Peterborough, terminating at a roundabout with the A1139, where the city bypass becomes the Frank Perkins Parkway. The road starts at the southernmost roundabout of the Glinton and heads eastward as a single carriageway before coming to a roundabout for local traffic. The road then becomes a major dual carriageway, although it has only one grade separated junction (with the A47), with the other junctions being roundabouts. In 2008, Peterborough City Council funded the dualling of the northernmost stretch of the Paston Parkway between two roundabouts east of Gunthorpe.

Intersecting the M2 at its second junction, crossing the A2 through the centre of Strood and meeting (and encompassing for a short stretch) the Northern Relief Road (A289). The road then carries on to the Isle of Grain. Throughout its passage through Strood it is single carriageway, but the stretches to the North are dualled partially toward Grain. The road to Grain was an accident black spot, this and increased traffic from the major port of Thamesport which is located to the north-west along the Medway Estuary prompted the construction of a new dual carriageway.

Leaving Parktown, the road begins to drop as it descends Parktown Ridge through the hilly and leafy suburbs of Westcliff and Forest Town. As it enters Parkview, it passes through the Herman Eckstein Park, with the Johannesburg Zoo to the right and the left Zoo Lake. Narrowing to single lanes in Saxonwold, Jan Smuts Avenue splits northwards at the Cotswold Drive (R25) winding its way out off Saxonwold and into Parkwood. It resumes as a dual carriageway as it climbs into the retail suburb of Rosebank and leafy Parktown North before dropping down into Dunkeld West as a single carriageway.

The Great North Cycleway was proposed in 2011 and was initially expected to take two years to complete The proposed Great North Cycleway is named after the Great North Road, historically the main highway between London and Scotland (until road building in the 20th Century routed motor traffic onto bypasses and motorways and away from urban areas). In 2015, Newcastle's John Dobson Street was converted from a dual carriageway back into a single carriageway road, using the reclaimed space to create a segregated cycleway, which forms part of the Great North Cycleway. As of 2019, large sections of the route are still unfinished.

Government and public opinion, Editorial in Irish Independent, p. 6; 4 September 1956Oireachtas Debates: The taking of £500,000 from the Road Fund, 20 June 1956 leaving both the Johnstown and Rathcoole sections of the road in a semi-finished state until the re-election of a Fianna Fáil government. The single carriageway by-pass was eventually replaced by a dual carriageway, opened by Neil Blaney on 25 June 1963, the first section of the Dublin-Naas road to be increased to four lanes. The local service station in Beaufort, owned by the Goosen family, became famous for its "open 24½ hours daily" sign.

These are used for pedestrian crossings. The purpose of the blister surface is to provide a warning to vision-impaired people who would otherwise, in the absence of a change of height of >25mm, find it difficult differentiate between where the footway ends and the carriageway begins. The surface is therefore an essential safety feature for this group of road users at pedestrian crossing points where the footway is flush to the carriageway, to enable wheelchair users to cross unimpeded. The profile of the blister tactile surface consists of rows of flat-topped blisters in a square pattern.

The A512 is an A road entirely in Leicestershire, UK. It links the primary destination of Loughborough with the M1, A42 road, and the town of Ashby de la Zouch. The road begins just outside Loughborough Town Centre, near to The Rushes It heads out of town, crossing the A6004 Epinal Way and passing Loughborough University. On leaving the town, there is a short dual carriageway section, leading to the junction with Snells Nook Lane to Nanpanton and Woodhouse. After this junction, the road returns to single carriageway for about , to Junction 23 of the M1.

The centre of these junctions are within half a mile of each other, with a tangle of inter-weaving slips roads, flyovers, and underpasses between and either side of them. The A71 meets the bypass at a roundabout over the carriageway, and the M8 terminates at a roundabout under the carriageway, along with access to Hermiston Gait retail park. The A71 provides one of the main routes into Edinburgh via Calder Road, and west to Livingston and Kilmarnock. The M8 runs to Glasgow and provides direct access to the M9 for Stirling, and via the M90 to the Queensferry Crossing.

On 3 December 1993, the PIE extension was opened from Jurong Road all the way to Upper Jurong Road, and converting parts of Upper Jurong Road into Pan Island Expressway. As the amount of traffic using the KJE and PIE to Jurong Industrial Estate increased, the Land Transport Authority upgraded the stretch of the PIE between Tengah Flyover and Tuas Road to a four-lane dual carriageway from a three-lane dual carriageway. The work started in March 2004 and ended in March 2006. Beginning in July 2011, the stretch of the PIE between Clementi Avenue 6 and Adam Road was widened.

Initial improvements to the road in the 1960s included widening small sections to 3 lanes (forming the so-called suicide lane) or to dual carriageway; but nothing more than . Andover and Amesbury were bypassed in 1969, while general improvements to the road, including additional dualling, took place throughout the 1970s. Parts of the A303 were upgraded to dual carriageway throughout the late 20th century. In 1971, the Environment Secretary, Peter Walker announced the entire length of the A303 would be upgraded as part of a new roads programme that would deliver 1,000 new miles of motorway by 1980.

On such occasions the trolley buses were not expected to cope with the crowds along the regular North Beach route so capacity was augmented by running extra trams up the Brighton tramline then back along the eastern end of the North Beach tramline to a point where they were met by trolley buses running shuttles to the Racecourse. As on Bealey Avenue, traffic ran in both directions on either side of the median strip on Fitzgerald Avenue. Trolley buses used the western carriageway between the Moorhouse Avenue depot and Kilmore Street, and the eastern carriageway between Heywood Terrace and Bealey Avenue. It was not until the withdrawal of the trolley buses that Fitzgerald Avenue could be converted to one direction per carriageway. A short-lived extension was started on 25 May 1936 using a petrol bus that was run out to North Beach from the City and back on scheduled services every day.

This caused his vehicle to travel straight on through a left- hand curve on the highway and collide with the Trans City Express coach. There was no indication that the driver had applied his brakes or dimmed the headlights, the coroner found. Neither coach was speeding at the time of the crash, and no mechanical faults were found in either vehicle. The coroner (Kevin Waller) endorsed the recommendation he made following the Grafton bus crash two months earlier, that the Pacific Highway be upgraded to dual carriageway between Newcastle and the Queensland border. The New South Wales and Commonwealth governments committed to carry out the required work, with an initial promised completion date of 2006. This target never came close to being met; at July 2008, only 267 kilometres (or 39%) of the route had been upgraded to dual carriageway standard, with 87 kilometres of divided road under construction and 325 kilometres of the highway still a single carriageway.

The North East's main arterial carriageway is the A1 road, which mirrors the East Coast Main Line's course. In County Durham this road is of motorway standard and is known as the A1(M), and in March 2018 a section of A1(M) was opened between Barton and Leeming Bar in North Yorkshire providing a continuous link to the motorway network in the rest of England. However, the A1 is still an all-purpose road in Tyne and Wear and Northumberland, and is controversially still single carriageway north of Morpeth, despite being the main trunk route connecting Edinburgh and Newcastle upon Tyne and having a terrible safety record. A second north-south dual carriageway link is provided by the A19 which heads north from Thirsk (accessed via the A168 from the A1(M) at Dishforth), serving Teesside, Peterlee and Sunderland before heading through the Tyne Tunnel to meet the A1 at Seaton Burn.

A small roundabout in Waterloo, Ontario. As the overall or external size of a roundabout (in the UK referred to as the Inscribed Circle Diameter – ICD) is reduced, so the maximum practicable (and prescribed) diameter for the central island is also reduced, whilst the width of the circulatory carriageway increases (due to the greater width of vehicle swept path at smaller turning radii). In most cases this results in it being too easy – certainly when traffic is light relative to capacity – for drivers to traverse the roundabout at relatively high speed, with scant regard for road markings or the potential dangers to self or conflicts with other road users. To mitigate this risk, a proportion of the circulatory carriageway – an annulus around the central island – is segregated from general use by demarcation lines and differentiated from the outer annulus of carriageway by a combination of slightly raised surface, adverse crossfall, contrasting colours and textures and demarcating lines.

The Levy Mwanawasa Stadium is a multi-purpose stadium in Ndola, Zambia. It is used mostly for football matches. The stadium has a capacity of 49,800 people. It is located on the T3 Road at the start of the Ndola-Kitwe Dual Carriageway.

A dual two-lane vehicular bridge was therefore constructed above the interchange with a view to easing the traffic volume channelling through the roundabout. With the opening of Pok Oi Flyover on 5 February 1999, vehicles travelling between Yuen Long Highway and Tai Lam Tunnel or San Tin Highway no longer have to enter the roundabout at Pok Oi Interchange. In order to accommodate the expected traffic from Route 10 cross-border corridor to and from Shekou/Dongjiaotou in Shenzhen over Deep Bay, the road had been finished upgrading to a dual 3-lane carriageway from its original dual 2-lane carriageway in February 2006.

The final 2-lane wide link connecting Kamal Amrohi studio and Saki Vihar Road was constructed in 1994. The JVLR had a varying cross section; the road was barely a 2-lane single carriageway for some of its length, with deficient geometry. It also carried significant goods traffic, and by 2002, was grossly inadequate to cater to traffic demand. In 1994, a comprehensive transport plan was prepared by MMRDA to arrest and improve the deteriorating transport condition in the Mumbai Metropolitan Region. The study recommended that the existing 2-lane wide JVLR be widened to a 6-lane carriageway, as well as other improvements.

In Chapelford, a recent housing development built on the old Burtonwood Airbase site, are a number of boulevards such as Boston and Santa Rosa Boulevard, named in reference to the American history associated with World War II on the site. Birmingham, known as the UK's Second City, has many dual-carriageway boulevards. Roads such as the A4040 (Outer Ring Road) and various other sections of dual-carriageway often have great amounts of trees, grass and scenery on both sides, as well as part of the wide central reservation. Other towns and cities have sections of roadway which could be described as boulevards where central tramways have been abandoned.

A van driver claimed something flew up in front of him, believed to be jackdaws, startling him and causing him to skid into the central reservation, but it was later reported that he fell asleep at the wheel. A car travelling behind the van changed lanes to avoid contact but other vehicles behind, which were travelling at speeds averaging 70 miles per hour, failed to avoid the crashed van and skidded into the other lanes of the carriageway. Others took evasive action by driving onto the hard shoulder and up the sides of the cutting. An articulated lorry then jack-knifed across all three lanes of the eastbound carriageway.

Dual carriageway trait in Rieti In Rieti SS4 turns sharply into East, quickly leaves the Rieti plain and prosecutes in the Velino valley. Shortly before Cittaducale, the road returns a single carriageway and pretty narrow road, which still needs to be uprated and follows a similar path to the ancient Roman road. While slightly ascending, SS4 reaches the spa town of Cotilia and then Antrodoco, where it joins State Highway 17 to L'Aquila. The Velino viaduct, in the Gole del Velino canyon In Antrodoco (470 metres on sea level) the road follows the river's valley, bending to the north and entering the narrow "Gole del Velino" canyon.

The route begins at M1 Junction 13 and enters Milton Keynes near Wavendon. Its route takes north of the Open University campus, Milton Keynes University Hospital, over the A5 and the WCML, a finally leaves for Buckingham at Tattenhoe. The H9 Groveway is partly dual-carriageway, running from the major roundabout junction with the A5 and V6 Grafton Street and terminating between Brinklow and Wavendon Gate, at a roundabout junction with Newport Road, the A421 and the H8 Standing Way. The H10 Bletcham Way starts as a dual carriageway at the three-way Granby Roundabout with the V6 Grafton Street and V4 Watling Street at Denbigh.

It is notable for Neath Hill Local Centre designed by Wayland Tunley as being one of the few local centres in Milton Keynes built to straddle the grid roads rather than being embedded within the interior of the grid square. Overgate continues from H5 Portway through Campbell Park to H6 Childs Way though this is not signed V9. The V10 Brickhill Street is mainly a single carriageway, but it is important in being one of the few that run continuously between the northern and the southern borders of the town. It is only a dual carriageway for 200 metres south of the H4 roundabout at Willen.

The road was constructed between 1895 and the Diamond Jubilee of Queen Victoria, after whom the road is named, in 1897. The road was originally a single carriageway, extending only as far as First Tower, however over time the road was extended and converted into a dual carriageway in the late 1950s. Between 2009 and 2010, upgrades to the road were part of a fiscal stimulus plan in response to the 2007 financial crisis. It involved the replaced of the aged drainage system, improvement of pedestrian facilities, the replacement of street lighting columns to improve energy efficiency and the lengthening of right- turn lanes to reduce congestion.

Berlinka in Russia, with original concrete carriageway on the right and later modern carriageway on the left Because of territorial changes of Poland and Germany following the war, the road was divided and lost its importance as a route between German cities (most of Prussia's German population was expelled to Germany). The part that remained within German borders became the Bundesautobahn 11. Certain segments of the route were nonetheless restored. In the People's Republic of Poland bridges over the Oder River near Szczecin were restored soon after the war, as were the bridges on the Banówka River near the border with the Kaliningrad Oblast.

Adriatic Highway near Makarska The highway near Tučepi Adriatic Highway south of Neum Bosnian border crossing north of Neum The highway near Jaz Beach, Budva The Adriatic Highway () is a road that stretches along the eastern coast of the Adriatic Sea and is part of the European route E65. The road passes principally through Croatia, with smaller stretches through Bosnia and Herzegovina and Montenegro. It is an undivided two-lane road for almost its entire length, with the exception of a short stretch through Zadar and a dual- carriageway section from Plano (Trogir) to the southeast suburbs of Split. The dual carriageway is planned to be extended further southeast to Omiš.

The A8 is a long branch which starts at Matulji in Primorje- Gorski Kotar County and finishes in Kanfanar interchange, at the crossing with the A9. The branch is built as a single carriageway limited-access road, but the part between Kanfanar and Pazin was projected as a dual carriageway, so all the objects on the road are already prepared for a conversion to a motorway. The most prominent feature of this branch of Istrian Y is the long Učka Tunnel, the third longest tunnel in Croatia. The tunnel was opened in 1981 and is the main road that connects the Istrian peninsula with Rijeka and the rest of Croatia.

By 1966 the Corporation were looking at the possibility of reducing the flow of traffic through the square by changing the route of the Inner Circuit Road to pass along The Grove and thence across the mouth of St Augustine's Reach. They even considered it possible that the road across Queen Square might eventually be closed if circumstances permitted. By the 1980s it was recognised that the dual carriageway was a "massive intrusion" on the amenity of the Square, and plans were made to "put things right". In 1992 the dual carriageway was closed to through traffic for an initial six-month trial period.

The A1231 originates as a single carriageway at the 'Whitehouse Road' / 'Addison Road' roundabout junction with the A1018 'Commercial Road' in Hendon. It then runs via the 'Esplanade' gyratory on the southern edge of Mowbray Park, just south of the city centre, to an intersection with 'Ryhope Road', which is the main road to the south of the city. Then, as 'Stockton Road', the A1231 heads north, past the Park Lane Interchange and toward the 'Priestman Roundabout' which is the end-point of the A690 road, the main trunk road to the south-west of the city and Durham. Immediately north of 'Priestman', the A1231 is a dual carriageway named 'St.

While the South Yorkshire police question the statement and say the road is no more dangerous than any other road of its type in Britain, judges sentencing traffic accidents have declared the road to have been built "on the cheap" and the mayor of Stocksbridge at the time of its construction declared it to be "fearfully dangerous". During the road's construction it was downgraded from a dual carriageway with crash barrier to a single carriage way with a passing lane. Since its completion there has been a 46,000-name petition demanding it be upgraded to dual carriageway. There are frequent head-on collisions on the bypass.

Lebuh Ayer Keroh, Federal Route 143, also known as Lebuhraya Ayer Keroh or Ayer Keroh Highway, is the main dual-carriageway highway that connects Malacca City of Malacca, Malaysia to the North–South Expressway via Ayer Keroh Interchange. Ayer Keroh, the main satellite town of Malacca City is located along the road. Lebuh Ayer Keroh used to be Melaka State Route M31 before being recommissioned by Malaysian Public Works Department (Jabatan Kerja Raya (JKR)). Before 1993, most of the road was a two-lane road before it was upgraded to a dual-carriageway in 1993 (Ayer Keroh Toll Plaza–Graha Makmur) and in 1997 (entire route).

The A380 leaves the A38 at Kennford, some from that road's junction with the M5 motorway, and from the centre of the city of Exeter. It then proceeds in a generally southerly direction, climbing over the Haldon Hills before descending past the towns of Kingsteignton and Newton Abbot and continuing on a single carriageway flyover over the Penn Inn roundabout heading towards Torquay. Beyond Newton Abbot, the road bypasses the village of Kingskerswell on the South Devon Highway. The road soon comes to Edginswell (a signal controlled junction) at Torquay where it meets the A3022 that (as Dual carriageway) serves the large seaside resort of Torquay.

The M57's Junction 2 lies several miles south-west of St. Helens, at Prescot. The M58 is several miles north, at the north-western end of the A570 Rainford By-Pass dual carriageway. The A580 East Lancashire Road runs north of the town centre alongside Eccleston, Moss Bank and through Haydock. It is a dual-carriageway former trunk road taking traffic from Manchester to the Liverpool Docks. It was built between 1929 and 1934 and was opened by King George V. It was intended to take pressure away from the A58, a major road running from Prescot (M57) through St Helens to the A1(M) at Wetherby, West Yorkshire.

This section was originally planned to be a 2 lane single carriageway with at-grade intersections, but because costs went down, it was changed so it can be constructed as a 4 lane dual carriageway with grade separated interchanges. Continuing on from the roundabout interchange with The Promenade in Ellenbrook, it goes north, passing built up areas in Ellenbrook, then going through rural areas. Along the way are roundabout interchanges with Stock Road and Neaves Road, and a flyover over Muchea South Road and the Midland railway line, and the current Brand Highway, before ending at a roundabout interchange with Great Northern Highway and a new Brand Highway.

Many sections of the A31 were upgraded to dual carriageway in the 1960s, except for the section of road running through the New Forest. The upgrade of the A31 through the New Forest started in the early 1960s, following two decades of debate. The Government's intention was to create at least one high-speed route to the south coast, while the guardians of the forest, the Verderers, resisted any further development. The first section of the A31 to be dualled was the section that the M27 feeds into at Jct1; the westbound carriageway is the original two-way A-road while the eastbound side was laid down nearby.

Before the M25 was built, the A21 was the modern A224 near Polhill and then became the dual carriageway Sevenoaks bypass. This section of the road is a grade separated dual carriageway with two lanes in each direction (aside from a three lane section northbound climbing Hubbards Hill). The road passes to the west of the town, running through a nearby valley until it meets the A225 and B245 at Morley's Interchange near Sevenoaks Weald. The next section bypasses the original route of the A21 along the B245 through Hildenborough, Tonbridge High Street, and Pembury Road to join the current route near the second A26 junction.

US 15 northbound past MD 140 in Emmitsburg US 15 was widened from downtown Thurmont north to Owens Creek starting in 1953. That same year, the highway was relocated as the first carriageway of an ultimate divided highway from Owens Creek to just south of the intersection of US 15 with St. Anthony and Orndorff roads south of Mount St. Mary's University. In 1956, construction began on the Thurmont Bypass, which was constructed as the first carriageway of an ultimate divided highway from south of Catoctin Furnace to just south of Owens Creek. The bypass, which included an interchange with MD 77, was completed in 1958.

On 2 August 1956, he received a memo from the Secretary of State for Transport about the matter, which stated "the plan is to complete the conversion in about 10 years. When this work is completed there will be a dual carriageway leading from the Border to Uddingston with no built-up areas along its length." By the early 1960s, these plans had changed to consider building a motorway in preference for the more straightforward online upgrades. The original section of the M74 in the mid-1960s ran from just north of Kirkmuirhill in South Lanarkshire, connecting to an earlier dual carriageway bypass, to Hamilton.

The road was initially built as a single connector route between the A1 and the Port of Ploče, at the time designated as part of A10. The dual carriageway part of the route was built in two phases, the first between finished in December 2008, and the second in December 2013. The dual carriageway extends from Karamatići to the Radonjić Viaduct. Under the current official road classification, , the D425 ends at the toll station, while the continuation of the road to the north, a expressway connector from the Karamatići toll plaza to the A1 Ploče interchange, is not classified as part of the D425.

The campaign was successful and a promise of funding for the new road was obtained from the National Roads Authority. After over a year of planning, construction of the new road was started in May 2009 with a projected completion date of December 2010. The project involved creating two major new sections of road and one smaller section. It consists of a 3.4 km dual carriageway linking the Limerick road roundabout north of Castleisland to the Tralee road west of the town, and a 1.6 km single carriageway continuing south from the roundabout on the Tralee road to meet the Killarney road roundabout southwest of the town.

Often on urban dual carriageways where the road has been converted from a four-lane single carriageway the central reservation will not be substantial: often just a small steel divider to save space. Turning right (that is, across the line of traffic heading in the opposite direction) is usually permitted only at specific locations. Often the driver will be required to turn left (away from the dual carriageway) in order to loop around to an access road that permits crossing the major road. Roundabouts on dual carriageways are relatively common, especially in cities or where the cost of a grade-separated junction would be prohibitive.

Improvements to the A13/A130 Sadlers Farm Junction were first given government approval in July 2006 following a 2005 public consultation. The project involved by-passing the roundabout by creating a new full-depth cutting link road between the A13 and A130, building slip roads connecting traffic to the Sadlers Farm roundabout and widening the A13 to dual four lane carriageway to Pitsea and the A130 to dual three lane carriageway to the Rayleigh Spur roundabout. The scheme is part of the Thames Gateway transport infrastructure plans which gave it an estimated cost of £63 million in 2007 and timelines it for 2012. The scheme was opened in 2012.

A bus lane, constructed in 2008 on the southbound carriageway of the A4032, Newfoundland Way, links the end of the M32 at junction 3 with Cabot Circus. It starts just south of junction 3 and runs for , adjacent to the central reservation, and becomes a general running lane for its final to a signal controlled junction. The hard shoulder and the remaining width of carriageway were rebuilt as two narrowed running lanes for general traffic, and the speed limit was reduced to . In 2009, the council announced that a park and ride facility would be developed next to the M32 to help alleviate congestion in the city centre.

The first section of the Bedford Western Bypass (from the A421 and the A428 road) was completed in December 2009. It is named after former mayor Frank BranstonBedford Today – Branston Way opens at last and is designated as part of the A428 trunk road. A new 13 km dual carriageway on the A421 opened on 1 December 2010 alongside the older carriageway between the M1 Junction 13 and the Bedford Southern bypass and a new bridge over the M1 together with changes to the A6 road. Bedford also has its own Park and ride operation situated to the south of the town near Elstow.

Peshawar Northern Bypass (Urdu: پشاور شمالی بائی پاس) or Northern Peshawar Highway is a [E-2] dual carriageway, grade separated road with controlled- access, designed for high speeds vehicles and heavy traffic coming from southern Pakistan. The bypass has two traffic lanes and an emergency lane in each carriageway. It bypasses the Provincial capital Peshawar from north with the purpose to carry the transit traffic bound toward Afghanistan, which has to pass through the city or via the Peshawar ring road. The bypass is an important thoroughfare, as it connects Indus Highway - N-55 (via Peshawar Ring Road), Khyber Agency and Mohmand Agency with Peshawar- Islamabad M1 motorway (Pakistan).

The London–Brighton turnpike ran through the centre of Crawley, forming the High Street and Station Road. When Britain's major roads were classified by the British government's Ministry of Transport between 1919 and 1923, it was given the number A23. It was bypassed by a new dual carriageway in 1938 (which forms the A23's current route through the town), and then later to the east side of the town by the M23 motorway, which was opened in 1975. This connects London's orbital motorway, the M25, to the A23 at Pease Pottage, at the southern edge of Crawley's built-up area. The original single-carriageway A23 became the A2219.

Much of this section of the road was widened to a high quality single carriageway standard over the 1980s, at an estimated cost of £24 million (£ million as of ), while Luss itself is now bypassed to the west of the village along a single carriageway bypass constructed between 1990 and 1992. At Tarbet, the A83 branches west to Campbeltown while the A82 continues to the north end of the loch. This part of the road is currently of a lower standard than the sections further south. It is sandwiched between the shoreline of the loch and the mountains to the west, and it runs generally alongside the West Highland Line.

It meets the B5211 at crossroads (Patricroft Bridge) and crosses the Bridgewater Canal, then there is a left turn for the B5231 (Green Lane) towards Patricroft railway station and Monton. Before long it enters the centre of Eccles proper, splitting into two as Church Street and Irwell Place going east, passing the library and a Morrisons, and Corporation Road going west. It meets a roundabout near the Eccles terminus of the Manchester Metrolink. It becomes the dual-carriageway Bentcliffe Way, meeting the A576 (for Trafford Park. It leaves the A576 near junction 2 of the M602, heading east as the single-carriageway Eccles New Road.

The term lay-by is used in the United Kingdom and Ireland to describe a roadside parking or rest area for drivers. Equivalent terms in the United States are "turnout" or "pullout". Lay-bys can vary in size from a simple parking bay alongside the carriageway sufficient for one or two cars only, to substantial areas that are separated from the carriageway by verges and can accommodate dozens of vehicles. Dorchester, UK Lay-bys can be found on the side of most rural UK roads except motorways that are not on sections of smart motorways (but for emergencies only) where the hard shoulder is missing.

Devon Expressway signage The A38 in Devon runs between Tamar Bridge outside Plymouth and junction 31 of the M5, where the motorway ends; this section is known as the Devon Expressway. It is mainly a two-lane dual carriageway which runs between Exeter and Plymouth serving as a continuation of the M5 motorway. It is a common route for tourists travelling to Cornwall, though those wanting to use a continuous dual carriageway route to Cornwall can use the A30 rather than the Devon Expressway. It then runs concurrently with the M5 until junction 27, where it splits and enters Somerset independent but parallel to the M5.

Small areas of farmland still exist near the road's eastern end in Caversham, which is the southernmost extent of the Swan Valley. Prior to the late 1970s, Benara Road extended west of Camboon Road, however it was cut off west of Camboon Road, and the cut off section was renamed Bramwell Road. Between 1981 and 1985, the road was upgraded to a four lane dual carriageway between Holden Drive and Della Road. On 18 December 1989, the Tonkin Highway extension to Benara Road was opened, as a traffic light controlled intersection, and the dual carriageway section of Benara Road was extended east to Tonkin Highway.

Benara Road was the northern terminus of Tonkin Highway until 11 November 1991, when Tonkin Highway was extended north to link to Reid Highway. In the 1990s, several intersections were modified to be roundabout intersections, and between 1995 and 1998, the dual carriageway was extended again, to Danube Avenue, which is still the current extent of the dual carriageway. From 2016 to 2018, the intersection with Tonkin Highway was converted to a flyover as a part of the NorthLink WA project. An interchange was considered, but it would have been too close to Tonkin Highway's interchange with Reid Highway, so that was not chosen.

The Werrington Parkway runs from the south of Glinton, where the A15 forks into the Peterborough east bypass and main road into the city centre. The road is dual carriageway from Glinton to the centre of Peterborough. There are no grade separated junctions along its route but does contain a number of smaller roundabouts which give direct and easy access to Werrington and its industrial estates. The Parkway then becomes less and standard dual-carriageway to which speed limits are in place to pass through New England and its retail park along with a major supermarket just prior to reaching the junction with the A47 at a major junction.

The A2 crossing the Medway at Rochester on the site of the Roman crossings, the medieval crossing was to the south Watling Street (the A2), the Roman road between the Port of Dover on the English Channel and London, runs through Medway. This route became particularly congested and led to the building of the M2 to bypass the Medway Towns to the south in the 1960s and was subsequently widened extensively at the turn of the 21st century. The A2 through the Medway Towns varies from single carriageway to dual carriageway to "one way" systems. In places it deviates from the original route of Watling Street.

This was not only the meeting point of the Birmingham to Nottingham road, and the A38 (former A446), but is also the meeting point of Warwickshire, Staffordshire and the former West Midlands county. At the roundabout is the Bassetts Pole Harvester, and a McDonald's. As a dual- carriageway trunk road at Carroway Head, it meets the B4151 from the left (for Roughley), and becomes the parish boundary between Hints and Drayton Bassett, and a single carriageway, as Sutton Road. It is only a trunk road for until it meets the A5, after crossing the Heart of England Way, Bourne Brook and the former A5, now the B5404, at Mile Oak, Fazeley.

North Road (Cardiff) tidal flow system, a 3-lane single carriageway The southernmost point of the route is in Cardiff Bay, outside the Wales Millennium Centre. It runs up Lloyd George Avenue (this was previously Collingdon Road, and the A470 previously ran along the parallel Bute Street), and continues along St. Mary Street in central Cardiff. The road then becomes North Road, and after a tidal flow system running to Maindy and then goes over the flyover at the Gabalfa interchange of the A48 and the A469. It becomes an urban dual-carriageway along Manor Way, with a speed limit and with many traffic-signalled crossings.

J17 on M7; the start/end point of the N77. This was the start point of the old N8 single carriageway. The M8 now begins at junction 19 further west of Portlaoise following the opening of the M7/M8 in May 2010 Junction 19 on the N7 route (M7 motorway from Naas to past Portlaoise) at Aghaboe marks the start of the N8 (see thumbnails). From here it proceeds southwards, passing under the R434 and R433 roads until it runs parallel to the single-carriageway R639 road, bypassing Abbeyleix, Durrow, Cullahill, Johnstown, Urlingford, Littleton, Horse and Jockey, Cashel, New Inn, Cahir, Skeheenarinky, Kilbeheny, Mitchelstown, Kilworth Mountain, Fermoy, Rathcormac, Watergrasshill and Glanmire.

Until the Kwinana Freeway extension in the early 1990s, Armadale Road terminated in Forrestdale. At this time, Forrest Road was the main road from Hamilton Hill to Armadale. The realignment of Forrest Road as the Kwinana Freeway was extended saw it renamed as Armadale Road up to the Freeway (with most of the remainder of the old Forrest Road being renamed North Lake Road.) Prior to 2003, Armadale Road was a single carriageway from Lake Road in Forrestdale, to Solomon Road near the freeway. However, as part of the Tonkin Highway extension from 2003 to 2005, Armadale Road was upgraded to a dual carriageway from Lake Road to Anstey Road.

Tiger Brennan Drive provides the most direct route for freight coming to and from the East Arm Port, instead of using the busy Stuart Highway which runs through established suburbs. Following the completion of major extension works in 2010, the original sections built as single carriageway in stages between 1987 and 1997 are being progressively upgraded to dual carriageway standard. Most major junctions on Tiger Brennan Drive are controlled by traffic lights, however the road is designed to be upgraded to freeway standard, with some suburban streets connected via limited access slip roads. Additionally, grade separated junctions are provided at Hidden Valley Road and the interchange with the Stuart Highway.

The Neath and Tennant Canal once reached to Glyn-neath, and has been restored to provide over four miles of walkable towpath between Resolven and Glynneath. The Vale of Neath Railway was built by Isambard Kingdom Brunel to carry coal to Swansea docks, and is still used for freight trains transporting coal from the Unity open cast mine at the north-east edge of the village. In 1996 the single- carriageway road along the length of the Neath valley was replaced with a major dual-carriageway, carrying the A465 trunk road from Llandarcy (near Neath) to Hirwaun in Rhondda Cynon Taf, which transformed the access along the Neath valley.

As Operation Brock was not used due to Brexit being delayed, the decision was made to partially revert the M20 back to its original state. This was done by reopening the eastbound carriageway fully, and keeping the steel barrier in the event that Operation Brock would have to be activated again in the following months due to the uncertainty of Brexit. The westbound carriageway has stayed at 50 mph. This has decreased safety to motorists travelling on the M20 whether Operation Brock is in force or not, as if they breakdown they are in a live lane and there are no warnings to other traffic like there are on Smart Motorways.

Ashbourne is linked to the M50 and Dublin City by 17 kilometres of motorway/high quality dual carriageway on the N2/M2 national primary route, which commences at junction 5 of the M50 motorway (13.5 km from Ashbourne). The road is a six-lane dual-carriageway from the M50 until exit 2, Cherryhound in Co. Dublin, where it becomes a motorway from there to the Rath roundabout, 1.5 km north of Ashbourne. The M2 incorporates a bypass of Ashbourne. The N2/M2 bypass allows commuters and hauliers to avoid the town on routes south from County Donegal, County Londonderry, County Tyrone, County Monaghan, County Louth and the rest of County Meath.

The expressway will start at Nakawa, a neighborhood in Nakawa Division in the eastern part of Kampala, go through Namanve and Mukono in Mukono District, and end at the New Jinja Bridge in Njeru. The entire expressway will be a four-lane, dual carriageway, with limited access.

Double yellow lines on the side of the road have a similar meaning (no parking at any time) as in the United Kingdom. Single yellow line adjacent to a kerb means parking is restricted at certain times. A broken yellow line marks the edge of the carriageway.

Weyhill railway station was opened on 1 May 1882, by The Swindon, Marlborough and Andover Railway, and closed on 11 September 1961.Aerial photo of station site The village is just north of the A303 dual carriageway. The A342 Andover to Devizes road runs through the town.

A total of six interchanges and overpasses will be built, one each in the six townships where the four-lane dual carriageway is planned to pass. This way, the traffic on the highway will not interfere or be impeded by the surface traffic in the urban centers.

The lifting span was fixed in position in 1940 as the need for river steamers ceased. The internal lift span is supported by twin cast iron cylinders. The timber truss spans are supported by timber trestles. The superstructure provides a carriageway with a minimum width of 5.1m.

About half of the southbound carriageway has been built but is unpaved, including the Bowen Street onramp which is now a walkway. The Shell Gully/Clifton Tce carpark under the motorway, accessible from the Terrace clearly shows the pillars, and part of the carriageway (now part of the carpark) that would have carried the additional three southbound lanes to the 2nd Terrace Tunnel. The northbound carriageway is almost complete with one exception, the Bowen Street offramp which would have been a counterclockwise loop splitting off from the Tinakori Road offramp. A section of the Tinakori Road offramp has a different type of barrier to the rest of the offramp, this shows where it would have been. Funding for the second tunnel was indefinitely shelved in the 1970s due to fiscal pressures on government, and the beginning of far greater scrutiny of the quality of highway expenditure. It was clear that until the Wellington Urban Motorway was connected to State Highway 1 at Ngauranga Gorge, that a single Terrace Tunnel would be adequate for the traffic demands of the 1970s.

The other nearby junctions were also converted to fly-overs in the 1990s. Travelling Southbound on the N18 near the Shannon Town/Airport exit. The road continues north with junctions at Hurler's Cross and Shannon Town, there is a fly-over connecting Shannon Airport via the N19 dual- carriageway.

Greek National Road 44 (, abbreviated as EO44) is a single carriageway road in central Greece. It connects Thebes with Karystos on southern Euboea, via Chalcis and Eretria. The total length of the GR-44 is nearly 160 km. The highway lies in the regional units of Boeotia and Euboea.

The Brighton Bypass is a A$191 million north/south bypass of the Midland Highway diverting traffic away from the northern Hobart satellite suburbs of Brighton and Pontville. Construction of the 9.5 km federally funded dual carriageway started in April 2009, and was opened on 12 November 2012.

Doe Lea is a small, linear village in the English county of Derbyshire. It is in the Bolsover district of the county and falls in the Ault Hucknall civil parish. The village runs along the old A617 road. A newer dual carriageway (currently the A617) runs parallel to it.

Orion Group's subsidiary companies are completing the Mayor Mohammad Hanif flyover in Dhaka. The dual carriageway flyover includes 11 slip roads or ramps (exit and entries) and will stretch from the Dhaka- Chittagong highway to Palashi. The contract is estimated to be completed by the end of 2014.

Later plans saw the road downgraded to an A road; it would have reached the M61 between junctions 5 and 6. These plans have also been dropped and currently Wigan Borough Council has plans for a part dual and part single carriageway route to the A579 near Atherton.

Beginning at Springburn in Glasgow as a dual carriageway, the A803 passes through the towns of Bishopbriggs, Kirkintilloch, Kilsyth, Banknock, Haggs, Bonnybridge, Falkirk, Laurieston, ending east of Linlithgow. It connects to the M80 at Haggs. It also joins onto the A801 which goes to Bathgate, Livingston, and Lanark.

Greek National Road 38 (, abbreviated as EO38) is a single carriageway road in western and central Greece. It connects Thermo with Lamia, via Agrinio and Karpenisi. It passes through the regional units Aetolia-Acarnania, Evrytania and Phthiotis. The section between Agrinio and Lamia coincides with the European route E952.

Pink News. Retrieved 31 January 2014. He was the only Liberal Democrat MP to oppose recognising Palestine as a state in the Commons vote on 13 October 2014. Beith campaigned throughout his years in the House of Commons for the A1 road to be made dual carriageway in Northumberland.

Water pipes were installed in the 1840-1860s, the carriageway was cobbled in the mid 18th century. Every household was in charge of the street section next to its house. In the 1830s the cobbles were replaced by timber blocks, which significantly reduced the noise from horse carriages.

The late 1980s saw a bypass of Killarney. In 2004, the Ballincollig bypass west of Cork city was completed. This is an dual carriageway road built to Motorway standards that connects with the N40 Cork South Ring Road. In 2005, of the road between Tralee and Farranfore was upgraded.

Greek National Road 76 (, abbreviated as EO76) is a single carriageway road in southern Greece. It connects the Greek National Road 9 near Krestena with Megalopoli, via Andritsaina and Karytaina. It runs through the western and the central part of the Peloponnese, in the regional units Elis and Arcadia.

After , the highway once more becomes a dual carriageway, and travels past residential neighbourhoods. Following , the highway takes on the name Hannan Street, and continues for through to downtown Kalgoorlie, terminating at Goldfields Highway on Kalgoorlie's eastern edge. Alternate Route 94 turns south, back towards the National Highway route.

The VG-20 is a Spain dual carriageway. It runs around Vigo, in the province of Pontevedra. A tunnel is under construction under the Park of Castrelos that would join the Avda. De Madrid (main entrance to the Center of Vigo from the East) with the First Belt.

The district's roads feed into the London radial route the A11 to the north. In the east of the district a single carriageway, the A112, links Stratford via West Ham to the north to the Excel Exhibition Centre by Custom House railway station where it terminates in the south.

Dag Hammarskjöld. Heron Books. The memorial is located 10 km west-north-west of Ndola on the Dag Hammarskjöld memorial access road off the Ndola-Kitwe Dual Carriageway. Göran Björkdahl interviewed several witnesses around the crash site in the 2000s and studied archival documents related to the Katanga crisis.

Junction 5 (south) of the M11 motorway linking Cambridge to London is accessed at Loughton's eastern boundary. The junction does not permit entry to north-bound carriageway, nor exit southbound. The M11 was constructed in a number of phases beginning in the 1970s and finally opening in the 1980s.

The road passes through Taddington Dale. Taddington has a dual-carriageway bypass. There are junctions with the B6049 (for Blackwell) and A5270, and it enters the district of High Peak and passes under four railway bridges. It enters Buxton as Bakewell Road and meets the B5059 at a roundabout.

The scheme will not be implemented until after 2016. Essex county council has put forwards plans for a bypass of Chelmsford connecting Junction 19 of the A12 to the A131. Plans to upgrade additional sections of the A120 into a dual two-lane carriageway were scrapped in 2009.

On 4 August 2006, a flyover of the Kinsale Road Roundabout was opened to traffic 6 months ahead of schedule. The project cost 55 million euro and consists of 3 lanes eastbound, 2 lanes west-bound and four on/off-ramps connecting the dual-carriageway to the roundabout.

The grounds include large areas of lawn to the north of the house, the early carriageway lined with mature trees and a tennis court to the east of the drive. At the southern end of the site the ground slopes steeply to the river, the bank being heavily vegetated.

Finally, a dual-carriageway bypass was opened in 1996. Sections of the old A11 were reclassified as the B1172 and now link Wymondham and Hethersett. A cycle path along the B1172 connects Wymondham to Norwich. The B1135 passes the northern edge of the town on its way to Dereham.

The entire outside walls are of flint construction, but inside walls facing the courtyard are of brick construction with low-pitched, hipped, slated roofs. The wing also has octagonal chimneys. The rooms have sash windows with glazing bars and there are large four-centered, arch-headed carriageway doors.

Heath, J. & Christian, R., (1985). Yesterday's Town: Derby. Buckingham: Barracuda Books, It was a mile from the town, but the Council built a carriageway to the town centre, along Siddals Lane, now Siddals Road. The station was built by the North Midland, with the other two companies renting spaces.

The dual-carriageway £62 million Norwich Bypass opened in September 1992. At the Longwater Intersection, the A1074 follows the former route through Norwich near the Longwater Retail Park and Sainsbury's. Near Bawburgh, it crosses the River Yare. There is a GSJ with the B1108, for Little Melton and Colney.

Heading due north the road passes Whitefield and cuts through Bury before crossing the M66 motorway at Junction 1. The road follows the M66 up to its terminus near Edenfield. The A56 becomes dual carriageway, and traffic from the M66 can continue onto this trunk road section only.

In 2005, a section of the road between Boas Avenue and Shenton Avenue was reduced from dual carriageway to an undivided road, primarily to provide additional at- grade on-street parking bays, but also to assist in the reduction of traffic flow and speeds through the central area.

It was constructed between 1955 and 1957. The bridge was officially opened in 1957 when Malaya achieved its independence from Britain, hence its name. The bridge was initially a 2-lane single carriageway bridge before being duplicated on another side for Penang-bound traffic to increase traffic capacity.

It consists of basalt cobbles for the carriageway, sandstone curbs and clinker brick walkways. From 1908, several prostitutes have been recorded as house owners. After the eastern entrance to the Rampenloch was closed with a wall in around 1960, the street is now only accessible from the Königswall.

There are some parts of the roads considered as freeways, although mostly in a state of complete neglect and disrepair since the collapse of the Soviet Union. The ring road around Tashkent is about 70 km. long, and completely multilaned, although it lacks a carriageway separation in most sections.

Tutnall is a village in the Bromsgrove district of Worcestershire. It is in the civil parish of Tutnall and Cobley which has a population of 1,543.Census 2001 The A448 used to run through the centre of the village, though this is now bypassed by a modern dual carriageway.

Upgrading of the existing dual carriageway to dual three-lane motorway standard, with a local road alongside for non-motorway traffic, between Dishforth (A1(M)/A168 junction) and Leeming Bar, began in March 2009 and opened to traffic on or about the scheduled date of 31 March 2012.

Type D highway is a dual carriageway urban road with sidewalk. In Italy are called strade urbane di scorrimento. If Type D highway travels across an urban area with more than 10,000 people, it is maintained by comuni, instead of ANAS. Speed limit in Type D highways is .

Type E highway is a single carriageway urban road with sidewalk. In Italy are called strade urbane di quartiere. If Type E highway travels across an urban area with more than 10,000 people, it is maintained by comuni, instead of ANAS. Speed limit in Type E highways is .

In the longer term however, the latest HS2 route through Measham and the consequential moving of the A42 dual carriageway, should allow bridges to be built, funded by the HS2 project, for the canal to cross under both HS2 and the A42 when reinstated between Measham and Moira.

Tentative plans to route traffic along Spencefield Lane were strongly opposed by residents, leaving it unclear where exactly the Distributor Road would be built. The A47 is not dual carriageway and is already congested at peak hours, so extending the A563 eastwards as far as open countryside seems problematic.

The A11 dual carriageway Thetford bypass is reputedly haunted by a phantom gamekeeper appearing on car bonnets. Whilst waiting at a traffic light, one driver witnessed a car from the 1930s pass and vanish. The road has been known to unsettle passengers and drivers, creating a sense of lethargy.

According to the Bossier Economic Development Foundation, the city could have reached 80,000 by 2019. Ongoing projects contributing to growth include the Walter O. Bigby Carriageway (the north parkway extension named for former state representative and judge Walter O. Bigby), Shed Road construction, and the South Bossier redevelopment districts.

In Moscow, the highway follows Zvenigorodskoe Shosse, Mnevniki Street, and Marshala Zhukova Avenue before crossing with Moscow Ring Road. The stretch between Moscow and Volokolamsk is known as Novorizhskoye Shosse. This is the only stretch (along with the part within the city of Moscow) built as a dual carriageway.

Where King Street ends at Sydney Park Road, the Princes Highway continues in its own right. The highway in this section is constructed as a six-lane divided carriageway, other than along King Street (four-lane undivided) and along the western edge of the Royal National Park, where it is built as four-lane dual carriageway.. The only major engineering structures along its route are the twin Tom Uglys Bridge across Georges River. The northbound bridge is of steel truss construction, opened in 1929, whilst the southbound bridge is of prestressed concrete girders, opened in 1987. It runs through Sydney's southern suburbs (the St George area and Sutherland Shire), via Kogarah, Sutherland and Engadine to the village of Waterfall.

From the southern end of the Princes Motorway at Yallah, the Princes Highway is dual carriageway, mostly to freeway standard, to Kiama Heights, with the exception of the section from the Illawarra Highway to Tongarra Road in , which is four lane undivided. Beyond Kiama Heights, south of Sydney, the highway is single two lane carriageway to Cambewarra Road, . Design and preparation works are underway for the duplication of the highway from Kiama Heights to Cambewarra Road. This duplication is intended to include a bypass of , but adheres to the extremely hilly route from the southern end of the bypass to Berry, rather than the flat terrain immediately to the east, which the Illawarra railway line follows.

Pembury has two by-passes, both constructed in the mid-1980s. The A21 bypass is a dual-carriageway road running through lower ground to the south of the village between the Longfield Road roundabout near North Farm, Tunbridge Wells and the Kippings Cross roundabout to the east of the village. Prior to the construction of this bypass, vehicles travelling between London and Hastings had to drive through the village centre via the High Street and Hastings Road. The A228 bypass is a single-carriageway road passing through woodland to the north and west of the village, linking Woodsgate Corner and the A264 with Maidstone Road at the northern end of the village near Pippins Farm and Downingbury Farm.

Map of the loch c. 1800 The main arterial route along the loch is the A82 road which runs the length of its western shore, following the general route of the Old Military Road. The road runs along the shoreline in several places, but generally keeps some distance to the west of the loch in the "lowland" section to the south. Much of the southern section of the road was widened to a high quality single carriageway standard over the 1980s, at an estimated cost of £24 million (£ million as of ), while Luss itself is now bypassed to the west of the village along a single carriageway bypass constructed between 1990 and 1992.

From the N4 to Adamstown, there is only one traffic lane and a bus lane in each direction (As the carriageways are separated by a jersey barrier this is still technically a dual carriageway). From Adamstown to Kingswood, the route has two lanes and a bus lane in each direction. However all junctions, other than the N4 junction and N7 flyover, are at-grade, and the median is rather narrow. R136 dual carriageway at Grange Castle The term Outer Ring Road should not be confused with Outer Orbital Route, which refers to an indicative plan to construct a second motorway bypass ring around Dublin (after the M50), further out from the city.

The project consisted of a freeway-standard extension as far as South Yunderup Road in South Yunderup, and a highway-standard dual carriageway to Old Coast Road at Lake Clifton. Taking traffic around the eastern side of the Peel-Harvey Estuary prior to joining the existing dual carriageway on Old Coast Road reduced the journey time from Perth to Bunbury. The final road names were not known until early 2009, when Transport Minister Simon O'Brien revealed that the section south of Pinjarra Road would be known as Forrest Highway, with the section to the north to become part of Kwinana Freeway. The highway's name commemorates Sir John Forrest, the state's first premier.

The clockwise carriageway is referred to as the inner ring (ring intérieur in French, binnenring in Dutch), while the anticlockwise carriageway is referred to as the outer ring (ring extérieur in French, buitenring in Dutch). The first sections of the road were built in the late 1950s, but the main part was built during the 1970s, with the end of construction in 1978. The Brussels Ring has interchanges with the European routes E40 (at the Groot-Bijgaarden and Sint-Stevens-Woluwe interchanges), E19 (at the Machelen and Ittre interchanges), E411 (at the Leonard crossroads), and E429 (at the Halle interchange). It also has interchanges with national highways A12 (at the Strombeek-Bever interchange) and A201 (at the Zaventem interchange).

The road is part primary, part non-primary, which reflects its status as a mix of local and regionally important traffic. The primary section of the road, under the name The Parkway (and part of it as Hayes Bypass), is a 5-mile dual carriageway trunk road with speed limits of 40 to 50 mph, running north–south from Northolt's Target Roundabout to the A30 interchange in Hatton. The non-primary section is mostly a single carriageway and consist of urban roads, particularly the northern part, where it serves as the main road of Northolt and South Harrow. The southern end goes through more residential areas and ends at the foot of Bushy Park.

The route length of a transport network is the sum of the lengths of all routes in the network, such as railways, road sections or air sectors. The U.S. Department of Transportation's Federal Transit Administration has also referred to this as "Directional Route Miles (DRM)". Where a network is made up of railways, route length has also been defined, by at least one source, as the sum of the distances (in kilometres) between the midpoints of all stations on the network. In a measurement of route length, each route is counted only once, regardless of how many lines pass over it, and regardless of whether it is single track or multi track, single carriageway or dual carriageway.

An upgrade to a stretch of the highway north of Townsville has been given approval, and will see the existing dual carriageway to the north extended by another 11 km. It will also include installation of traffic lights at Mt Low Parkway, and will be the final stage of the Ring Road link up to this section by 2015. The Queensland Main Roads Department's ultimate concept map of the development shows that the highway will progressively become Motorway standard by 2015, with the implementation of interchanges at various junctions. The highway south of Cairns will see sections of the highway to the suburb of Edmonton become six lanes, with progressive dual-carriageway redevelopment of the highway to Gordonvale.

However, these have been done in a piecemeal fashion so that the road varies in quality and capacity along its length and still has several unimproved single carriageway sections and awkward junctions. By comparison, very little has been done to improve the condition of the South Circular Road (A205) (which has complex junctions and forks) and no part of the southern part of Ringway 2 has been built, mainly because of the density of the residential areas through which the South Circular runs. The road remains predominantly single carriageway throughout. One relic of the scheme is Southwyck House in Brixton, which was deliberately designed to shield noise from Ringway 2, leading to its nickname of "Barrier Block".

The A303 road passing by Stonehenge The A303 primary route is one of the main routes from London to the South West of England. Sections have been upgraded to dual carriageway status, though one third of the road remains single carriageway. Traffic flows on the A303 between Amesbury and Winterbourne Stoke (the section including Stonehenge) are above the capacity of the road and the Highways Agency expressed concern about safety on this road and the A344. The two roads passed through Stonehenge and land owned by the National Trust with the A303 passing directly south and the A344 directly to the north, with a pedestrian tunnel passing from the Stonehenge visitor centre to the site underneath this road.

Therefore, it sometimes appears to be more of a widened mountain road, rather than a motorway or an expressway. For the whole of the ramps towards the culmination at the San- Bernardino tunnel, between Thusis and Soazza, there is no central structure to separate the two carriageway directions; each lane is about 50 percent larger than on a main highway, and overtaking (using part of the carriageway reserved for the other direction) is allowed where signposted. The expressway finds its way through the Alps by means of the San Bernardino tunnel, which is in length. It also passes the Viamala gorge, where nocturnal shows tell the story of 2000 years of road construction through this obstacle (summer only).

There have been calls (by both Republic of Ireland and Northern Ireland political parties) to upgrade the whole Dublin-Derry route to dual carriageway, including the A5 in Northern Ireland. In October 2006, the Irish government announced it was funding infrastructure costing €1 billion in Northern Ireland, and one possible project to be funded is the upgrading of the A5 Derry–Omagh–Aughnacloy road to motorway standard for a distance of . However, there was no mention of the N2 road being upgraded to motorway standard in the Republic. The Irish Department of Finance website confirmed on 22 March 2007 that £400 million had been set aside for Northern investment to include a dual carriageway to Derry and Donegal.

It was unclear if any of this would be built in the Republic. The 2007 Fianna Fáil election policy document on transport includes a dual carriageway from Dublin to Letterkenny/Derry as one of Fianna Fáil's promises if re-elected. Although the N2 is not included in Transport 21 and the recently opened Monaghan and Carrickmacross by-passes are single lane national primary roads, a recent feasibility report completed on the N2 Ashbourne to Ardee section recommends a dual carriageway cross section (this includes the Slane By-pass). Also in order to tie in with the A5 Western Transport Corridor north of the border work on the feasibility study for the N2 Clontibret to NI Border Scheme has commenced.

The arch on the south side has a keystone bearing the inscription "DAVID LENNOX", on the north side, "AD 1833", the packing of the bridge to either hand of the main ashlared section is of coursed rubble revetments, making the total length of the bridge carriageway of almost . The stone parapets are laid above a projecting plinth which begins just above the keystones. The area between the curve of the arch and the horizontal carriageway was packed with small rubble stone. There was originally a damp-proof lime-mortar course above the vaulting, but this, together with most of the packing, was removed when the bridge was stripped back to the arch in 1976.

North West Coastal Highway's southern terminus at Brand Highway was upgraded from a roundabout to an interchange, and an overpass was built for Durlacher Street to cross North West Coastal Highway. The highway was also made into a dual carriageway in the vicinity of the interchange. Stage 2 of the project, constructed between December 2008 and December 2009, provided a single carriageway connection from a traffic light-controlled intersection on the highway to Geraldton–Mount Magnet Road, with access to Geraldton Airport. In 2013 work began on a project to seal the highway's shoulders from Yannarie River at Barradale to the Onslow turn-off; it is expected to be completed by mid-2015.

The third section of A33 starts at the Chilworth Roundabout, a junction with the M3 and A27, and runs south into the centre of Southampton and further south to Ocean Village. It then turns west and into dual carriageway at a roundabout near the Isle of Wight ferry terminal, past the docks and through Town Quay to run along West Quay Road, continuing past Leisure World and Ikea (which is partially responsible for congestion on the road and immediate surroundings due to its popularity, particularly on weekends). The A33 then bears left slightly to carry on along the Millbrook Road West dual carriageway to meet the M271 and A35 at Redbridge Flyover.

On Thursday 4 December 2014 McCartney was able to confirm that the £49.5m of funding for the Eastern Bypass was secure and that the Government would support in principle a future bid for the bypass to be a dual carriageway. This funding comes nearly 5 years after the original plan for a dual carriageway bypass was cancelled by the Conservative led coalition for being too costly. As of April 2015 work has not commenced and it is unclear when or if it will as it does not feature in the Coalition's Road Investment Strategy. McCartney claimed however to have received verbal assurances from Government Ministers that the funding was secure and the project would go ahead.

Described as "North Wales' most notorious road", the A55 or the "North Wales Expressway", is a dual carriageway primary road in Britain from the M53 near Chester to Holyhead, along the North Wales coast and passing Deeside, Llandudno Junction, Conwy and Bangor. It is an economic lifeline for North Wales, and the second most important road in all of Wales, only to the M4 in South Wales. The road connects to the Port of Holyhead, which provides ferry connections to the Republic of Ireland. The majority of the road is part of the E-road network as E22 (until Ewloe), and is a dual carriageway, grade-separated, for its entire 88 mile length.

A very early (perhaps the first) example of a dual carriageway was the Via Portuensis, built in the first century by the Roman emperor Claudius between Rome and its port Ostia at the mouth of the Tiber. One claim for the first divided highway in the United States was Savery Avenue in Carver, Massachusetts, first built in 1860, where the two roadways were separated by a narrow strip of trees down the middle.Henry S. Griffith, History of the Town of Carver, Massachusetts: Historical Review, 1637-1910, New Bedford, MA: E. Anthony & Sons, 1913. In 1907 the Long Island Motor Parkway opened, and roughly 20% of it featured a semi-dual-carriageway design.

The pillars of Castle Hill Viaduct have been reused for the North Devon Link road The road starts in Ilfracombe as part of the town's High Street, and is mostly single carriageway. The road passes through the villages of Knowle and Braunton, before becoming dual carriageway standard at Ashford, which continues for the short distance to Barnstaple. From there it passes the town's railway station then merges with the A39 for a short while before splitting back off near Portmore Golf Park. The section from Barnstaple to the M5 near Tiverton has been designated the North Devon Link Road, and enables relatively fast access to the Atlantic Highway, relieving pressure on the northern section of the A39 and A358.

When the original motorway sections were built in the 1960s, the motorway was numbered south-to- north, with Draffan at its southern terminus with the A74 Dual Carriageway being junction 1 and Maryville junction 6. When the M74 was to be extended south of Draffan in the 1980s, it was renumbered, in 1984 in preparation for the opening of the southern extension, north-to-south. The Raith or Raith remained as J5, while Maryville became J4, allowing for later extension Northwards, towards Glasgow. The original junction 1 at Draffan was closed, with the first new junction 9 (Blackwood) replacing it, using the southbound carriageway of the old A74 as a slip road.

The road starts on the A66 at Middlesbrough (South Bank) and heads south east through Ormesby to Nunthorpe where it turns east as a dual carriageway bypassing Guisborough and the road becomes single carriageway again. Just outside Guisborough it heads into the North York Moors National Park (forming its boundary at first). As it passes the village of Charltons, it rises up at a 15% incline through two 90° turns (the first east then the second south) up to Low Moor, this hill is named Birk Brow. The road then wends its way through the open moorland of the North York Moors park past Scaling Dam and down into Whitby where it heads across Whitby new bridge.

By June 1961, excavation work was underway at the northern end of Bishop Street to process piping and electrical services in the area. to install piping was complete, The foundations for the new road were laid from July 1961, starting with the southern side of the road at the intersection with Bishop Street. Work on the roadway was underway by early August, Tarmac work began on southbound stretch from Swanswell Terrace to Hill Cross during the week of 14 August, and it opened to traffic on 22 August. The southbound carriageway on the Bishop Street to Radford Road section opened on 22 August 1961, with the northbound carriageway following on 8 November 1961.

The deviations were an attempt to ease the gradients against heavily laden Sydney-bound steam trains. The Breadalbane-Derringullen Creek deviation is in most places quite close to the previous highway, most of which remains for local use. This section also included the abandoning of the route over the Mundoonen Range which, when it was rebuilt in the 1960s, was designed to be duplicated. Between Conroys Gap and Coolac, most of the earlier alignment was replaced in 1983 and 1996 by realignment associated with dual carriageway construction, although sections such as that south of Connors Creek were rebuilt in 1979 with the earthworks being done for a second carriageway, which was subsequently built in 1994.

Along the bypass there are exits for Stoneleigh and the University of Warwick, Kenilworth and Leamington Spa (A452). At the Warwick (A429) exit, the bypass drops down to two lanes, closely followed by an exit for the A4177 and Warwick Parkway railway station. The M40 is passed over west of Longbridge roundabout, as a new bypass now brings the mainline carriageway away from Junction 15, the A46 meets a small roundabout, connecting with the B4463 and a link to Junction 15 for northbound A46 traffic to access the M40 and A429 respectively. The dual carriageway section south of the improved Longbridge island is the only part of the A46 on its original routing between Leicester and Cheltenham.

The A30 begins at Henlys Roundabout, where the route stems from the A4 near Hounslow. It runs south of the Southern Perimeter Road, Heathrow Airport and north of Ashford and Staines-upon-Thames, before reaching the M25 motorway orbital motorway. This first section is entirely dual carriageway. Taken with the A4, its natural continuation which nearby becomes non-dualled towards the M25, the section constitutes one of five routes into the southern half of London which reach Inner London with at least a dual-carriageway, the others being the A3 (M), the M3, the M20 and A2, however approximately one mile before reaching Inner London it is combined with the London variants of the M3 and M4 approaches.

MD 144 continues east as Old National Pike, a two-lane undivided road that is paralleled by an unused carriageway immediately to the north that serves as a park and ride and the original alignment further north, which is lined with scattered residences. The two southern carriageways cross the Monocacy River on bridges while the northernmost road dead ends at the site of the removed Jug Bridge. East of Bartonsville Road, MD 144 expands to a four-lane divided highway, with the westbound direction making use of what to the west was an unused carriageway. The original alignment, Baltimore Road, now parallels the highway to the south, while Long Branch parallels the highway to the north.

Unlike national roads, regional roads are maintained by local county or city councils rather than the National Roads Authority. The vast majority of the regional road network is made up of single-carriageway roads although some roads are dual-carriageway (see: High- capacity regional roads below). Until the late 1990s, such roads were often in a very poor condition, although increased road maintenance funding to local councils has resulted in more frequent resurfacing of regional roads, as well as relaying and realignment on some routes. Regional roads are generally subject to a speed limit of 80 km/h (imperial equivalent 50 mph), rather than the 100 km/h (imperial equivalent 62.5 mph) for national roads.

The motorway's first, and only, service station, Birchanger Green Services at Junction 8, opened in 1996. The services also serve the A120, a major high-speed dual-carriageway road, running from Junction 8A to the eastern fringe of Braintree, it continues on to Colchester as a busy single- carriageway road. There had been plans for a service station on the motorway as long ago as 1969, named Chigwell, between that village and Loughton, which led to the construction of spur roads and a restricted lorry park; during the London Olympics 2012 these were used as a works unit. The plans for a service station at this site were officially dropped in 1980.

The A5 once ran through the town centre, until a bypass was built in the 1930s. Subsequently, in 1992, a 17-mile (27 km) dual carriageway was completed at a cost of £79 million to the south of the town and was made to form part of the A5 route. This dual carriageway was built further out of the town to act as a substantial link to Telford, as well as a bypass for the town. The A49 also goes to Shrewsbury, joining the A5 at the south of the town, coming from Ludlow and Leominster. At this point, the road merges with the A5 for , before separating again to the east of the town.

The most significant road scheme in Belfast for some years began early in 2006, with the upgrading of two junctions along the Westlink dual carriageway to grade separated standard. The Westlink, a dual carriageway skirting the western edge of the City Centre, connects all three Belfast motorways and has suffered from chronic congestion for some years. The work will cost £103.9 million and is scheduled for completion in 2009. Some commentators have argued that this may simply create a new bottleneck at the at-grade York Street intersection until that too is converted to a fully free-flowing grade separated junction, which in 2007 was expected to take place between 2011 and 2016.
