Location

The Chateaubriand Bridge is a concrete deck arch road bridge in Brittany, France, that crosses the Rance river. For geographical conditions and technical traditions, France does not have many arch bridges.

History

Under construction

Design

The need for a bridge was envisaged by SETRA (Service d'études sur les transports, les routes et leurs aménagements).

Construction

It had a cantilever construction with cable-stays (staying wires). The steel construction was by Compagnie Française d'Entreprises Métalliques, now owned by Eiffage. It was built with high performance Class C60 concrete.

Structure

The bridge carries the European route E401 or Route nationale 176. It is near Plouër-sur-Rance and La Ville-ès-Nonais. The bridge spans the two departments of Ille-et-Vilaine, to the east, and Côtes-d'Armor, to the west.
