[edit] Construction
The bridge was designed by Michel Virlogeux. The architects were François Doyelle and Charles Lavigne.[1] Construction by Bouygues, Campenon Bernard, Dumez, Monberg & Thorsen now part of MT Hoejgaard, Quillery, Sogea and Spie Batignolles[1] began in 1988 and lasted 7 years. The bridge opened on 20 January 1995.
At that time the bridge was both the longest cable-stayed bridge in the world, and had the record for the longest distance between piers for any cable-stayed bridge. It was more than 250 m longer between piers than the previous record. This record was lost in 1999 to the Tatara Bridge in Japan. Its record for length for a cable-stayed bridge was lost in 2004 to the 2883 meters of the Rio-Antirrio. At the end of construction, the bridge had cost $465 million and was financed by Natixis.
The cable-stayed design was chosen because it was both cheaper and more resistant to high winds than a suspension bridge.
[edit] Structure
The span, 23.6 metres (77 ft) wide, is divided into four lanes for traffic and two lanes for pedestrians. The pylons, made of concrete, are shaped as upside-down Ys. They weigh more than 20,000 tons and are 214.77 metres (705 ft) tall. More than 19,000 tons of steel and 184 cables were used.
