Alexandre Gustave Eiffel was a French civil engineer. A graduate of École Centrale des Arts et Manufactures, he made his name with various bridges for the French railway network, most famously the Garabit Viaduct. He is best known for the world-famous Eiffel Tower, designed by his company and built for the 1889 Universal Exposition in Paris, and his contribution to building the Statue of Liberty in New York. After his retirement from engineering, Eiffel focused on research into meteorology and aerodynamics, making significant contributions in both fields.
A viaduct is a specific type of bridge that consists of a series of arches, piers or columns supporting a long elevated railway or road. Typically a viaduct connects two points of roughly equal elevation, allowing direct overpass across a wide valley, road, river, or other low-lying terrain features and obstacles. The term viaduct is derived from the Latin via meaning "road", and ducere meaning "to lead". It is a 19th-century derivation from an analogy with ancient Roman aqueducts. Like the Roman aqueducts, many early viaducts comprised a series of arches of roughly equal length.
The Ribblehead Viaduct or Batty Moss Viaduct carries the Settle–Carlisle railway across Batty Moss in the Ribble Valley at Ribblehead, in North Yorkshire, England. The viaduct, built by the Midland Railway, is 28 miles (45 km) north-west of Skipton and 26 miles (42 km) south-east of Kendal. It is a Grade II* listed structure. Ribblehead Viaduct is the longest and the third tallest structure on the Settle–Carlisle line.
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 Cornwall Railway company constructed a railway line between Plymouth and Truro in the United Kingdom, opening in 1859, and extended it to Falmouth in 1863. The topography of Cornwall is such that the route, which is generally east–west, cuts across numerous deep river valleys that generally run north–south. At the time of construction of the line, money was in short supply due to the collapse in confidence following the railway mania, and the company sought ways of reducing expenditure.
The Digswell Viaduct, also called Welwyn Viaduct, is a railway viaduct that carries the East Coast Main Line over the River Mimram in the county of Hertfordshire in England. A prominent local landmark, it is located between Welwyn Garden City and Digswell. It is just to the south of Welwyn North railway station.
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 Mala Rijeka Viaduct is a viaduct on the Belgrade–Bar railway, located some 20 km north of Podgorica, Montenegro.
The Sioule is a 164-kilometre (102 mi) long river in central France, a left tributary of the river Allier. Its source is near the village of Orcival, north of Mont-Dore, in the Massif Central. The Sioule has cut a deep gorge, especially in its upper course. The Sioule flows generally northeast through the following departments and towns:
Bennerley Viaduct is a former railway bridge, now a foot and cycle bridge, between Ilkeston, Derbyshire, and Awsworth, Nottinghamshire, in central England. It was completed in 1877 and carried the Great Northern Railway's (GNR) Derbyshire Extension over the River Erewash, which forms the county boundary, and its wide, flat valley. The engineer was Samuel Abbott, who worked under Richard Johnson, the GNR's chief engineer. The site required a bespoke design as the ground would not support a traditional masonry viaduct due to extensive coal mining. The viaduct consists of 16 spans of wrought iron, lattice truss girders, carried on 15 wrought iron piers which are not fixed to the ground but are supported by brick and ashlar bases. The viaduct is 60 feet high, 26 feet wide between the parapets, and over a quarter of a mile long. It was once part of a chain of bridges and embankments carrying the railway for around two miles across the valley but most of its supporting structures were demolished when the line closed in 1968. The only similar surviving bridge in the United Kingdom is Meldon Viaduct in Devon.
The Kinzua Bridge or the Kinzua Viaduct was a railroad trestle that spanned Kinzua Creek in McKean County in the U.S. state of Pennsylvania. The bridge was 301 feet (92 m) tall and 2,052 feet (625 m) long. Most of its structure collapsed during a tornado in July 2003.
The Solkan Bridge is a 219.7-meter (721 ft) arch bridge over the Soča River near Nova Gorica in western Slovenia. With an arch span of 85 meters (279 ft), it is the world's longest stone arch railroad bridge. It holds this record because later construction technology used reinforced concrete to build bridges. It was originally built to carry the Bohinj Railway in the time of the Vienna Secession, between 1900 and 1905, and officially opened in 1906.
The Crumlin Viaduct was a railway viaduct located above the village of Crumlin in South Wales, originally built to carry the Taff Vale Extension of the Newport, Abergavenny and Hereford Railway (NA&HR) across the Ebbw River.
The River Irwell Railway Bridge was built for the Liverpool & Manchester Railway (L&MR), the world's first passenger railway which used only steam locomotives and operated as a scheduled service, near Water Street in Manchester, England. The stone railway bridge, built in 1830 by George Stephenson, was part of Liverpool Road railway station. The bridge was designated a Grade I listed building on 19 June 1988.
The Makatote Viaduct takes the North Island Main Trunk railway (NIMT) across the Makatote River in New Zealand. It is 335.7 km (208.6 mi) from Wellington, at the foot of Ruapehu, in northern Manawatū-Whanganui, between Erua and Pokaka.
The canton of Saint-Georges-de-Mons is an administrative division of the Puy-de-Dôme department, central France. It was created at the French canton reorganisation which came into effect in March 2015. Its seat is in Saint-Georges-de-Mons.
The Chirk Viaduct is a Grade II* listed railway viaduct over the River Ceiriog between England and Wales. The viaduct carries the Shrewsbury–Chester line from the Welsh town of Chirk in historic Denbighshire from the north to the English village of Chirk Bank in Weston Rhyn, Shropshire to the south. To the east, the Chirk Aqueduct lies parallel to the railway viaduct.
The pier of a bridge is an intermediate support that holds the deck of the structure. It is a massive and permanent support, as opposed to the shoring, which is lighter and provides temporary support.
