Inside the Thames Tunnel during construction, 1830 In 1805 the Thames Archway Company was formed with the intention of driving a tunnel beneath the Thames between Rotherhithe and Limehouse. Richard Trevithick was engaged by the company to construct the tunnel. He used Cornish miners to work on the tunnel. In 1807 the tunnel encountered quicksand and conditions became difficult and dangerous. Eventually the tunnel was abandoned after more than 1,000 feet had been completed, and expert opinion, led by William Jessop, was that such a tunnel was impracticable.

Magnetic tunnel junction (schematic) Tunnel magnetoresistance (TMR) is a magnetoresistive effect that occurs in a magnetic tunnel junction (MTJ), which is a component consisting of two ferromagnets separated by a thin insulator. If the insulating layer is thin enough (typically a few nanometres), electrons can tunnel from one ferromagnet into the other. Since this process is forbidden in classical physics, the tunnel magnetoresistance is a strictly quantum mechanical phenomenon. Magnetic tunnel junctions are manufactured in thin film technology.

During 1862, Richardson spent time in the European Alps to study the latest tunnel construction techniques and equipment on the Fréjus Rail Tunnel project. This experience was put to good use during the tunnel construction, which was carried out through volcanic rock. The tunnel project, completed in 1867, was one of the greatest engineering achievements in early New Zealand. It was the colony's first rail tunnel and the first tunnel in the world to be driven through the side of an extinct volcano.

The final renovation was triggered by the massive highway project known as the "Big Dig". Since the Red Line tunnel beneath Summer Street is perpendicular to Atlantic Avenue, where the new I-93 northbound tunnel was to be built, builders had to tunnel under the tracks. After the first tunnel was complete, another tunnel was added along with a station for the Silver Line. Since the new tunnel was built at the former fare level, another fare level was constructed a level above.

The Brookville Tunnel (also Brooksville Tunnel) was a historic railroad tunnel engineered by Claudius Crozet during the construction of the Blue Ridge Railroad in the 1850s. The tunnel was part of a series of four tunnels used to cross the Blue Ridge Mountains of Virginia for the Virginia Central Railroad of the United States. The Brookville Tunnel was the second tunnel used to cross the mountains from the east (the easternmost being the Greenwood Tunnel), and was located approximately west of the village of Greenwood, Virginia. During its construction, numerous cave-ins and landslides occurred because of the fragile and weak rock the tunnel passed through, and at one point, an outbreak of cholera forced work to stop.

For water crossings, a tunnel is generally more costly to construct than a bridge. However, navigational considerations at some locations may limit the use of high bridges or drawbridge spans when crossing shipping channels, necessitating the use of a tunnel. Examples of such tunnels include the Downtown Tunnel and Midtown Tunnel under the Elizabeth River between Norfolk and Portsmouth, Virginia in the United States, the George Massey Tunnel in Greater Vancouver, Canada, and the Cross-Harbour Tunnel under Victoria Harbour between the twin cities of Victoria and Kowloon in Hong Kong. In other instances, when longer distances are involved, a bridge–tunnel may be less costly and easier to ventilate than a single, lengthy tunnel.

A double-track tunnel with restricted clearances is sometimes singled to form a single track tunnel with more generous clearances, such as the Connaught Tunnel in Canada or the Tickhole Tunnel in New South Wales, Australia. In the case of the Tickhole Tunnel a new single-track tunnel was built and the two tracks in the original tunnel were replaced by one track in the centreline of the tunnel. Another case where this was necessary was the Hastings Line in the United Kingdom, where the tunnels were eventually singled to permit the passage of standard British-gauge rolling stock. Before the singling, narrow-bodied stock, specially constructed for the line, had to be used.

Bombardier Talent of Euregiobahn leaves Eilendorf Tunnel A 727-metre-long tunnel called the Nirmer Tunnel (Nirm Tunnel) was built between Stolberg and the location of modern Eilendorf at line-km 63.6 during the construction of the line and completed in 1841. Both miners from Eschweiler and workers from the Leipzig–Dresden railway were employed in the construction of the tunnel, using a method known as core construction (Kernbauweise—using three narrow tunnels to build the walls of the final tunnel before the tunnel core was removed). There were eight chimneys above the tunnel for the extraction of smoke produced by the steam locomotives. During the Second World War a bunker was built over the west portal.
|
|
In 1963, it became clear that the cross- section of the tunnel, like the Königsdorf Tunnel and the Ichenberg Tunnel, was too narrow to allow the catenary to be installed. Therefore, the Nirm tunnel was partially opened out and converted into two smaller tunnels lined with concrete. The western tunnel is the Eilendorf Tunnel with a length of 357 metres (line-km 63.9) and the eastern tunnel is the Nirm Tunnel with a length of 125 metres. Although the two newly constructed tunnels were designed for speeds of up to 200 km/h and high-speed tests had been carried out with class E 03 locomotives, the permissible top speed today is 130 km/h.

However, unlike a sonic boom, tunnel boom is not caused by trains exceeding the speed of sound. Instead, tunnel boom results from the structure of the tunnel preventing the air around the train from escaping in all directions. As a train passes through a tunnel, it creates compression waves in front of it. These waves coalesce into a shock wave that generates a loud boom when it reaches the tunnel exit.

Similar conclusions were reached for the 1971 Kingsway Tunnel under the Mersey. In Hampton Roads, Virginia, tunnels were chosen over bridges for strategic considerations; in the event of damage, bridges might prevent US Navy vessels from leaving Naval Station Norfolk. Water-crossing tunnels built instead of bridges include the Holland Tunnel and Lincoln Tunnel between New Jersey and Manhattan in New York City; the Queens-Midtown Tunnel between Manhattan and the borough of Queens on Long Island; the Detroit-Windsor Tunnel between Michigan and Ontario; and the Elizabeth River tunnels between Norfolk and Portsmouth, Virginia; the 1934 River Mersey road Queensway Tunnel; the Western Scheldt Tunnel, Zeeland, Netherlands; and the North Shore Connector tunnel in Pittsburgh, Pennsylvania. Other reasons for choosing a tunnel instead of a bridge include avoiding difficulties with tides, weather, and shipping during construction (as in the Channel Tunnel), aesthetic reasons (preserving the above-ground view, landscape, and scenery), and also for weight capacity reasons (it may be more feasible to build a tunnel than a sufficiently strong bridge).

In 1971, the track was electrified between Frankfurt-Höchst and Niedernhausen, and in 1986 between Niedernhausen and Limburg. Eastern portal of the old Eppstein tunnel Starting in 2009 the tunnel in Eppstein was replaced with a new tunnel because the old tunnel needed to be restored urgently and doing this with full operation of services would have led to years of disruption of rail services. In addition, a new tunnel would be cheaper in the long run, as a new concrete lining inside the tunnel would reduce the cross-section to the extent that it could no longer be operated as two tracks, and therefore a new tunnel would have to be built for traffic in the opposite direction anyway. The line was rerouted through the new tunnel during the Easter of 2013 and the old tunnel was subsequently filled.

General George R. Dyer, the chairman of New York's Bridge and Tunnel Commission, and Theodore Boettger, the chairman of the New Jersey's Interstate Bridge and Tunnel Commission jointly co-signed letters to each state's governor. After the Manhattan-Queens tunnel was formally recommended by the New York City Board of Estimate in June 1929, the heads of each state's respective bridge and tunnel commissions reiterated their proposal to extend the Manhattan-Queens tunnel to New Jersey. The New York State Legislature considered two proposals for the Weehawken–Manhattan tunnel in January 1930. Although both would connect Weehawken to 38th Street in Manhattan, one proposal called for the Port Authority to build and operate the tunnel, while the other would entail operations by the "Joint Tunnel Committee", composed of the bridge and tunnel commissions of both states.

Since the Bering Sea at the proposed crossing has a maximum known depth of 170 feet (50 m), the tunnels might be dug with conventional tunnel boring machines of the type that was employed in the construction of the Channel Tunnel. The three tunnel proposal is considered to be preferable over a bridge due to severe environmental conditions, especially the inescapable winter ice damage. Each proposed tunnel would be shorter than some current tunnels. The Channel tunnel linking England with mainland Europe is approximately 31.34 miles (50.45 km) long; the ocean tunnel Seikan Tunnel linking Hokkaido with Honshu in Japan is 33.46 miles (55.86 km) long; and the Swiss Gotthard Base Tunnel through the Alps, opened in 2016, is 35.7 miles (59.60 km) long.

This corridor over Rollins Pass was always intended to be temporary until what would later become the Moffat Tunnel was constructed and opened; therefore this overmountain route was constructed with more cost-effective materials: using wooden trestles (made of all Oregon fir) instead of iron bridges or high fills and wyes instead of turntables."Steamboat Pilot June 10, 1903 — Colorado Historic Newspapers Collection". www.coloradohistoricnewspapers.org. Construction of this route was exceptionally dangerous and deadly: in a single day, 60 Swedish workers were killed when a powder charge exploded prematurely during the construction of Needle's Eye Tunnel. Along this route were three tunnels: Tunnel #31 (the tunnel at Ladora), Tunnel #32 (Needle's Eye Tunnel), and Tunnel #33 (the Loop Tunnel at Riflesight Notch).

In response to the automobile boom in Switzerland and other things, the Swiss government gave approval in July 1969 for the construction of the Gotthard Road tunnel. The tunnel would be longer than any existing road tunnel, and would provide a year-round road link from the Swiss Plateau to southern Switzerland, and from northern to southern Europe as well, to be used in place of the Gotthard Pass. The tunnel was built roughly parallel to the old railway tunnel, with portals a few hundred metres away from those of the railway. Prior to the opening of the tunnel, cars were transported through the nearby railway tunnel on car shuttle trains.

Tunnels are dug in types of materials varying from soft clay to hard rock. The method of tunnel construction depends on such factors as the ground conditions, the groundwater conditions, the length and diameter of the tunnel drive, the depth of the tunnel, the logistics of supporting the tunnel excavation, the final use and the shape of the tunnel and appropriate risk management. There are three basic types of tunnel construction in common use. Cut-and-cover tunnels are constructed in a shallow trench and then covered over.

The Gibraltar Tunnel is proposed to be a rail tunnel linking Africa and Europe. Due to the depth of the Strait of Gibraltar (300–900 metres / 1000–2950 feet), it would be a great challenge to remove automobile exhaust from this depth. Any tunnel would most likely be an electrified rail tunnel, similar to the Channel Tunnel linking the UK and France. There have also been proposals for a bridge over the Strait.

Dr. Syama Prasad Mookerjee Tunnel comprises two tubes that run parallel to each other — the main traffic tunnel of diameter 13 m and a separate safety or escape tunnel of diameter 6 m alongside. The two tubes — each approximately 9 km long — are connected by 29 cross passages at regular intervals of every 300 metres along the entire length of the tunnel. These passages add up to about 1 km of tunnel length, and the main and escape tubes, plus the cross passages make up about 19 km of tunnel length. Since such a long tunnel could present the problem of a lack of oxygen, to ensure that there is no excessive carbon- dioxide build-up inside, there are several exhaust metres that will check the air all through the length of the tunnel. With inlets, every 8 metres, bringing fresh air into the main tube, and exhaust outlets every 100 m opening into the escape tube, the tunnel is the country’s first — and the world’s sixth — road tunnel with a transverse ventilation system.

Besides the direct rail connection, the Claremont Hotel was also convenient to vehicular traffic, as it was situated along the principal route over the Berkeley Hills via Claremont Canyon. In 1903, a small tunnel was excavated above Temescal Canyon (the next canyon southward), accessible by a new road dubbed Tunnel Road, which ran from the end of Ashby Avenue. The same route later led to a newer, larger tunnel which opened in 1937 as the "Broadway Low Level Tunnel", later re-named the Caldecott Tunnel. The street address of the Claremont is still 41 Tunnel Road.

Isaacs stated that a bridge would cause as much congestion as a tunnel would, so he did not favor the bridge plan. The Tunnel Authority also opposed the Brooklyn-Battery bridge because a bridge would lower property values. In response, Moses predicted that the Tunnel Authority's Queens-Midtown Tunnel would not be profitable, and that the Tunnel Authority should organize its existing affairs before deciding to build a new tunnel. Moses was able to garner support for the bridge from influential city and state politicians, including four of five borough presidents, Mayor La Guardia, and U.S. Senator Robert F. Wagner.

As part of the Stuttgart 21 project another railway tunnel will be built to replace the current Rosenstein tunnel. The preservation of the existing tunnel was examined but rejected in the course of the planning approval process because this would have meant that the railway network would have continued to divide the lower castle garden (Schlossgarten). The 3.4 km long tunnel will run between the new Neckar Bridge and the existing S-Bahn tunnel at the Central Station. The tunnel will initially start as two twin tubes at the Neckar Bridge, one carrying the S-Bahn and one carrying the long-distance tracks.

The Swiss government has decided to upgrade the second tunnel into a full road tunnel in order to allow for the necessary reconstruction of the first road tunnel. Once the works on the first tunnel are finished, the Swiss government plans to operate one single lane in each tunnel (northbound traffic in the newly constructed tunnel, southbound traffic in the renovated one) in order to maintain the current tunnel overall capacity, in compliance with the Swiss constitutional norm that forbids a further growth of the traffic capacity across the Alps. The reconstruction would have lasted for several years in any variant – one variant would push the traffic over the mountain pass, another proposed to load the vehicles onto trains with a new terminal, a third would close the tunnel for several months every year over time range of a decade. All of these have their drawbacks and the usage of the second tunnel was chosen as the best option to allow for the reconstruction.

Singstad is widely known for work on the underwater road tunnels in New York City and for designing the ventilation system that made long underwater road tunnels possible, first used in the Holland Tunnel under the Hudson River. He began working under chief engineer Clifford Milburn Holland in 1915,About Agdenes Township and he finished directing construction of the Holland Tunnel after the death of Holland in the fall of 1924 and of Holland's successor Milton H. Freeman, who died in March 1925. Singstad also designed the Lincoln Tunnel, the Brooklyn–Battery Tunnel, and the Queens–Midtown Tunnel, the latter two as chief engineer of the New York City Tunnel Authority. In this capacity he clashed with Robert Moses, who preferred bridges: In 1946, the Tunnel Authority was taken over by the Triborough Bridge Authority, forming the Triborough Bridge and Tunnel Authority, whereupon Singstad was fired, and the incomplete Brooklyn-Battery Tunnel was finished to specifications by TBTA chief engineer Ralph Smillie.

It consists of two tubes, the first of which was constructed between 1965 and 1970 and acted as the first vehicular tunnel underneath the Huangpu River in. The tunnel has two lanes and originally operated with one lane in each direction.

The southern terminus of Heung Yuen Wai Highway, known as Fanling Highway Interchange, is where four viaducts connect the highway to Fanling Highway. Built using the balanced cantilever method, the viaducts were assembled from 1,300 pieces of precast concrete segments. The highway travels northeastward as a dual-tube tunnel under Bird's Hill (also known as Lung Shan, ) called Lung Shan Tunnel. The tunnel is the longest land-based road tunnel in Hong Kong, longer than the previous record holder Tate's Cairn Tunnel.
