The Verrières Viaduct is a curved 720-metre concrete autoroute box girder bridge in the south of France, which at one point was briefly the highest bridge in France; it is almost 500 feet tall.
Société d'études techniques et économiques (SETEC) carried out design work for the shape of the road deck.
In August 1999, construction began of the steel deck structure on-site.
In January 2002, the bridge deck was incrementally launched from one side.
[3] The steelwork was built by Société d'études R. Foucault et Associés (SERF) of Cergy in Paris (Île-de-France).
