High Speed 1 (HS1), legally the Channel Tunnel Rail Link (CTRL), is a 109.9-kilometre (68.3-mile) high-speed railway linking London with the Channel Tunnel.
A cable-stayed bridge has one or more towers, from which cables support the bridge deck. A distinctive feature are the cables or stays, which run directly from the tower to the deck, normally forming a fan-like pattern or a series of parallel lines. This is in contrast to the modern suspension bridge, where the cables supporting the deck are suspended vertically from the main cable, anchored at both ends of the bridge and running between the towers. The cable-stayed bridge is optimal for spans longer than cantilever bridges and shorter than suspension bridges. This is the range within which cantilever bridges would rapidly grow heavier, and suspension bridge cabling would be more costly.
The River Medway is a river in South East England. It rises in the High Weald, West Sussex and flows through Tonbridge, Maidstone and the Medway conurbation in Kent, before emptying into the Thames Estuary near Sheerness, a total distance of 70 miles (113 km). About 13 miles (21 km) of the river lies in East Sussex, with the remainder being in Kent.
The M2 is a 26-mile-long (42 km) long motorway in Kent, England, and was built to bypass a section of the A2 road in Kent, which goes through the Medway Towns, Sittingbourne, and Faversham. It provides an alternative route to the Port of Dover, which supplements the M20 motorway located further to the south. The terminal junctions of the M2 intersect with the A2, which come together to form a 62-mile-long (100 km) long trunk road from London to Dover.
The M20 is a motorway in Kent, England. It follows on from the A20 at Swanley, meeting the M25, and continuing on to Folkestone, providing a link to the Channel Tunnel and the ports at Dover. It is 50.6 miles (81.4 km) long. Although not signposted in England, this road is part of the European route E15. It is also used as a holding area for goods traffic when traffic across the English Channel is disrupted, such as Operation Stack and Operation Brock.
Eugène Freyssinet was a French structural and civil engineer. He was the major pioneer of prestressed concrete.
The Millau Viaduct is a multispan cable-stayed bridge completed in 2004 across the gorge valley of the Tarn near Millau in the Aveyron department in the Occitanie Region, in Southern France. The design team was led by engineer Michel Virlogeux and English architect Norman Foster. As of October 2023, it is the tallest bridge in the world, having a structural height of 343 metres (1,125 ft).
The Kingston Bridge is a balanced cantilever dual-span ten lane road bridge made of triple-cell segmented prestressed concrete box girders crossing the River Clyde in Glasgow, Scotland.
Ebbsfleet International railway station is in Ebbsfleet Valley, Kent, 10 miles east of London, England, near Dartford and the Bluewater Shopping Centre to the west and Gravesend to the east. The station, part of the Thames Gateway urban regeneration project, is on the High Speed 1 (HS1) rail line, 300 metres south-west of Northfleet railway station, off the A2 trunk road, 5 mi (8.0 km) from its junction with the M25 motorway. It served as a primary park-and-rail service for the London 2012 Olympics.
Christian Menn was a renowned Swiss civil engineer and bridge designer. He was involved in the construction of around 100 bridges worldwide, but the focus of his work was in eastern Switzerland, especially in canton Graubünden. He continued the tradition of and had a decisive influence on Swiss bridge building. The technical and aesthetic possibilities of prestressed concrete were most fully realized with his bridges in Switzerland.
The Loughor railway viaduct carries the West Wales Line across the River Loughor. It is adjacent, and runs parallel to, the Loughor road bridge. The 1880 viaduct was granted Grade II listed building status. Before it was demolished in early 2013, the viaduct was the last remaining timber viaduct designed by Isambard Kingdom Brunel.
The Hawkesbury River railway bridge is a heritage-listed railway bridge in New South Wales, Australia that carries the Main North railway line across the Hawkesbury River. The bridge crosses between Brooklyn on the northern outskirts of Sydney and Cogra Bay in the Central Coast region. The railway bridge was to be the last link in a railway network that linked the state capitals Adelaide, Melbourne, Sydney and Brisbane and was a major engineering feat at the time. The original railway bridge was built in 1889 and replaced by the current bridge in 1946. The 1946 bridge was added to the New South Wales State Heritage Register on 2 April 1999.
The North Downs Tunnel, also known as the Blue Bell Hill Tunnel, is a railway tunnel that carries High Speed 1 through the North Downs, at Blue Bell Hill near Maidstone in Kent, south-east England.
The Newmarket Viaduct is a seven-lane state highway viaduct in Auckland, New Zealand. The 700 m long viaduct, which is up to 20 m high, carries the Southern Motorway over the Newmarket suburb.
The Langwieser Viaduct is a single track reinforced concrete railway bridge spanning the Plessur River and the Sapünerbach, near Langwies, in the Canton of Graubünden, Switzerland.
Pedro Álvares Ribeiro do Carmo Pacheco is a Portuguese civil engineer and professor of bridges at the Engineering Faculty of Porto University. He also co-founded BERD, a bridge engineering company. Pacheco is the mentor of the organic prestressing system concept, based on the human muscle, used in bridge engineering worldwide.
The Hølendalen Bridges are three parallel concrete cantilever bridge which cross Hølendalen in Vestby, Norway. One carries two tracks of the Østfold Line, the other two carry four lanes of European Road E6. The bridges have four spans, the two in center at 128 meters (420 ft) and the two outer at 80 meters (260 ft). The overall lengths are 416 meters (1,365 ft). The bridges are up to 50 meters (160 ft) above the valley and the creek of Såna.
The Byker Viaduct is a 2,674 ft (815 m) curved S-shaped light railway bridge, which carries the Tyne and Wear Metro over the River Ouseburn in Newcastle upon Tyne. It carries the line from Manors Metro station in the city centre to the west, to Byker Metro station in the area of Byker to the east, over the lower Ouseburn valley, with the river emptying into the north side of the River Tyne, to the south. It was one of two major bridges built specifically for the Tyne and Wear Metro, the other being the Queen Elizabeth II Bridge crossing the River Tyne.
The Colne Valley Viaduct is a bridge, under construction as of 2024, which will carry the High Speed 2 railway over the Colne Valley Regional Park and the Grand Union Canal, in Hillingdon, west London. When completed, its length of 3.4 kilometres (2.1 mi) and a weight of 116,000 tonnes will make it the largest railway bridge in the UK. It is one of the largest single civil engineering works of HS2 Phase 1.
The Wendover Dean Viaduct is a railway viaduct currently under construction that will carry the High Speed 2 (HS2) railway line across farmland between Wendover and Great Missenden, Buckinghamshire, England.
