Viaduc de Millau
The Millau Viaduct spans 2.5km of the gorge valley of the Tarn River. It is the tallest multi-span cable-stayed bridge in the world. Designed by an English and a French architect. Built by a consortium of experts led by Eiffage S.A., builders of the Eiffel Tower. Prized for its elegant design, innovation and engineering excellence – and 7 patents.
The Millau Viaduct is a product of Government, science and industry partnerships. Relating, recognising, supporting and connecting.
U Bein Bridge
The U Bein Bridge is believed to be the oldest and longest teak wood bridge in the world. It stretches 1.2 kms across Taungthaman Lake in the ancient capital of Amarapura, on the outskirts of Mandalay.
After the second Anglo-Burmese War, when the capital shifted to Mandalay, U Bein the mayor of Amarapura, salvaged 1,000 pillars of teak wood from the old Inwa Palace to construct the bridge.
Engineers placed pillars by counting their footsteps and using traditional scaling techniques.
The bridge has remained an important passageway for over 150 years, helping children get to school, fishermen to channel their catch and locals to reach important religious sites and markets.
Golden Gate Bridge
San Fransisco, California, USA
The Golden Gate Bridge is a suspension bridge spanning the Golden Gate, the one-mile-wide (1.6 km) strait linking San Francisco to Marin County.
The final suspension design was conceived and championed by Leon Moisseiff, the engineer of the Manhattan Bridge in New York City. He produced the basic structural design, introducing his “deflection theory” by which a thin roadway would flex in the wind, greatly reducing stress by transmitting forces via suspension cables to the bridge towers.
Charles Ellis, a Greek scholar, mathematician, and engineer he did much of the technical and theoretical structural design work. Irving Morrow, designed the overall shape of the bridge towers, the lighting scheme, and Art Deco elements, such as the tower decorations, streetlights, railing, and walkways.
When opened in 1937, it was the longest and tallest suspension bridge in the world, with a main span of 1,280m, and a total height of 227m.
High Trestle Bridge
Madrid, Iowa, USA
The bridge was originally built in the 1970’s over the Des Moines rive valley to carry rail traffic on a Milwaukee Road line.
When the rail line was retired, the original bridge deck was replaced with a new pedestrian and bicycle traffic deck.
The bridge decking incorporates a decorative structure that represents the view through a mine shaft, a throwback to Italian migrant families who once worked nearby mines.
The structure includes decorative lighting that remains on until 10:30pm in summer and 9:00pm in winter.
The High Trestle Trail Bridge is recognised as one of the eight amazing footbridges in the world.
Dames Point Bridge
Jacksonville, Florida, USA
The Dames Point Bridge is the longest concrete cable-stayed bridge in the United States (3.2kms).
A concrete pouring milestone was set during construction of the northern pier foundation 14,400 cubic metres of concrete was continuously poured for 47 hours.
The concrete and steel deck is suspended by 168 steel cables which extend from the towers and connect to the edge girder of the span at 11m intervals.
The longest cable is 240m long, the shortest 65. 33kms of steel cables are used overall.
It is the only bridge in the United States to feature the harp (parallel) stay arrangement on two vertical planes, a design which rivals suspension bridges for strength and elegance.
A Futuristic Bridge
If designed and built this could be amazing!
Sydney Harbour Bridge
The Sydney Harbour Bridge is a steel through arch bridge across Sydney Harbour that links traffic between the Sydney CBD and the North Shore.
Under the direction of Dr John Bradfield of the NSW Department of Public Works, the bridge was designed and built by British firm Dorman Long and Co Ltd of Middlesbrough and opened in 1932.
A bridge across the harbour is said to have been suggested in 1815 by Francis Greenway, convict and architect, to Governor Lachlan Macquarie..
The Sydney Harbour Bridge is the sixth longest spanning-arch bridge in the world and the tallest steel arch bridge, measuring 134m from top to water level. It was also the world’s widest long-span bridge (48.8 m), until 2012 when construction of the new Port Mann Bridge in Vancouver was completed.
79% of the steel was imported from England, with the rest being sourced from Newcastle. The bridge is held together by 6m rivets.
