The Rauze Viaduct is a concrete box-girder bridge located in southern France, at around 330 ft high. The bridge can carry heavy vehicles and loads on the A20 autoroute. It crosses the specific River Rauze.

History

[edit]
Construction in June 2000

Design

[edit]

The structural engineering was by SECOA (Société d'étude et de calculs en ouvrages d'art).[3] It is a haunched girder bridge. The area is designated under Natura 2000 as a natural fauna ecological area, so none of the piers could be put in the river. The three central spans are 130 m long, with the other outer spans being 91 m and 74 m long.

Construction

[edit]

It was built by Dodin Campenon-Bernard, with the balanced cantilever method. Pre-stressing was by Spie Précontrainte (Spie Batignolles) of Cergy in Paris. 28,000 cubic metres of concrete were required; the limestone came from a quarry in Cahors. Steel fabrication was by SAMT of Saint-Chamas. The autoroute scheme was completed on 20 June 2001, and opened on 12 July 2001.

Structure

[edit]

It is in the Lot department in the Occitanie region, 5 km north-west of Cahors.
