The Strand underpass is a one-way road tunnel in central London connecting Waterloo Bridge to Kingsway near Holborn. Opened in 1964, it was built within the former Kingsway tramway subway, which closed in the 1950s.
The underpass is built within part of the former Kingsway tramway subway, which was 20 feet (6.1 m) wide and allowed bi-directional flow because of the fixed rails and relatively narrow width of the trams. The new underpass was built by John Mowlem & Co [1] and opened on 21 January 1964. It is only 17 feet (5.2 m) wide and, as a result, it is normally one-way northbound because of the side clearances required. The headroom is only 12.5 feet (3.8 m) due to the tunnel having to pass beneath the bridge abutment by a 1:12 gradient. An electronic 'eye' alerts drivers of tall vehicles and diverts them to an 'escape route' to the left of the entrance. However, high vehicles do still try to pass through and so get stuck occasionally.
The underpass is a concrete box within the former tram subway, with the road surface at the original track level. At the northern end of the underpass the road rises to the surface on a new carriageway supported by metal pillars. This passes through the site of the former Aldwych tramway station; because of the greater width requirement, 27 trees and some pavement sections were removed for it to be constructed.
The tunnel was used by the 521 bus route northbound until it was withdrawn in April 2023. In 2012, the direction of traffic in the tunnel was temporarily reversed, so that it was in use by southbound traffic. This was to facilitate easier traffic flow during the 2012 Summer Olympics.
A roundabout, also known as a rotary or traffic circle, is a type of circular intersection or junction in which road traffic is permitted to flow in one direction around a central island, and priority is typically given to traffic already in the junction.
The Kingsway tramway subway is a cut-and-cover Grade II Listed tunnel in central London, built by the London County Council, and the only one of its kind in Britain. The decision in 1898 to clear slum districts in the Holborn area provided an opportunity to use the new streets for a tramway connecting the lines in the north and south. Following the pattern of tramways in New York and Boston, it was decided to build this as an underground connection.
Holborn is a London Underground station in Holborn, Central London, located at the junction of High Holborn and Kingsway. It is served by the Central and Piccadilly lines. On the Central line the station is between Tottenham Court Road and Chancery Lane stations; on the Piccadilly line it is between Covent Garden and Russell Square and is in Travelcard Zone 1. Close by are the British Museum, Lincoln's Inn Fields, Red Lion Square, Bloomsbury Square, London School of Economics and Sir John Soane's Museum.
The Blackwall Tunnel is a pair of road tunnels underneath the River Thames in east London, England, linking the London Borough of Tower Hamlets with the Royal Borough of Greenwich, and part of the A102 road. The northern portal lies just south of the East India Dock Road (A13) in Blackwall; the southern entrances are just south of The O2 on the Greenwich Peninsula. The road is managed by Transport for London (TfL).
The Rotherhithe Tunnel, designated the A101, is a road tunnel under the River Thames in East London, connecting Limehouse in the London Borough of Tower Hamlets north of the river to Rotherhithe in the London Borough of Southwark south of the river. It was formally opened in 1908 by George, Prince of Wales, and Richard Robinson, Chairman of the London County Council. It is a rare example of a road tunnel where road traffic, pedestrians and cyclists all share the same tunnel bore. Transport for London took over ownership and maintenance of the tunnel in 2001.
Aldwych tramway station was a tram stop underneath Kingsway, a road in central London, England. It was built in 1906 by the London County Council Tramways as part of the Kingsway tramway subway, joining the separate networks of tramways in North and South London.
Holborn tramway station was a tram stop underneath Kingsway in central London, England. It was built in 1906 by the London County Council Tramways as part of the Kingsway tramway subway, joining the separate networks of tramways in North and South London. When opened it was named Great Queen Street.
The Dublin Tunnel, originally and still commonly known as the Port Tunnel, is a road traffic tunnel in Dublin, Ireland, that forms part of the M50 motorway.
The median strip, central reservation, roadway median, or traffic median is the reserved area that separates opposing lanes of traffic on divided roadways such as divided highways, dual carriageways, freeways, and motorways. The term also applies to divided roadways other than highways, including some major streets in urban or suburban areas. The reserved area may simply be paved, but commonly it is adapted to other functions; for example, it may accommodate decorative landscaping, trees, a median barrier, or railway, rapid transit, light rail, or streetcar lines.
A single-point urban interchange, also called a single-point interchange (SPI) or single-point diamond interchange (SPDI), is a type of highway interchange. The design was created in order to help move large volumes of traffic through limited amounts of space safely and efficiently.
There have been two separate generations of trams in London, from 1860 to 1952 and from 2000 to the present. There were no trams at all in London between 1952 and 2000.
The A4200 is a major thoroughfare in central London. It runs between the A4 at Aldwych, to the A400 Hampstead Road/Camden High Street, at Mornington Crescent tube station, via Holborn, Bloomsbury, Euston and Somerstown.
A subway, also known as an underpass, is a grade-separated pedestrian crossing which crosses underneath a road or railway in order to entirely separate pedestrians and cyclists from motor traffic or trains respectively.
The Grand Duchess Charlotte Bridge is a road bridge in Luxembourg City, in southern Luxembourg. It carries the N51 across the Alzette, connecting Avenue John F. Kennedy, in Kirchberg, to Boulevard Robert Schuman, in Limpertsberg. The bridge is also known as the Red Bridge on account of its distinctive red paintwork. It is the main route connecting the city centre, Ville Haute, to Kirchberg, the site of the city's European Union institutions.
The U-Bahn Line B is the second line in the network of the Frankfurt U-Bahn. It leads in west–east direction from the central railway station (Hauptbahnhof) over the old town to Konstablerwache, where it splits into two branches to Bornheim and Preungesheim. Originally planned as an independent main line, the D line represents an extension of the U4 to Bockenheimer Warte from the central railway station.
The Frankfurt am Main tramway network is a network of tramways forming a major part of the public transport system in Frankfurt am Main, a city in the federal state of Hesse, Germany.
The U1 is an underground line in Nuremberg. The first part of the line was opened on 1 March 1972. It is about 18.5 kilometres (11.5 mi) long and has 27 stations. The termini are Langwasser Süd in the southeast and Fürth Hardhöhe in the northwest. Until 11 December 2016 it shared tracks with the former booster line U11 between Eberhardshof and Messe. Those services are still run but no longer designated U11, instead being signed U1 like trains doing the full Langwasser-Hardhöhe run. Unlike U2 and U3 all trains are operated by a driver and there are no plans to automate U1.
The A line is the north-to-south main line of the Frankfurt U-Bahn. It is the oldest and longest line of the U-Bahn system. Served by four routes starting at Südbahnhof Railway Station in Sachsenhausen, the A line runs through downtown Frankfurt up to Heddernheim Station in the north of the city, where it branches out to Ginnheim, Oberursel (U3), Riedberg and Bad Homburg (U2). The U9 service between Ginnheim, Riedberg and Nieder-Eschbach does not use the central section and tunnels of the line, making it the only light rail service of the network that does not serve downtown Frankfurt. The Riedberg and Ginnheim branches were planned as parts of the future D line subway but are operationally part of the A line until the D line development and construction is finished.
The Line C is a line on the Frankfurt U-Bahn. It consists of the U6 and the U7.
The Royal Commission on London Traffic was a Royal commission established in 1903 with a remit to review and report on how transport systems should be developed for London and the surrounding area. It produced a report in eight volumes published in 1905 and made recommendations on the character, administration and routing of traffic in London.
