Inauguration of line B of the Rennes metro

This is an emblematic project in which Eiffage Génie Civil participated, in a consortium with Razel-Bec, by building the 2.4 km viaduct linking the "Beaulieu - Université", "Atalante" and "Cesson-Viasilva" stations.

This is a real source of pride for all the teams involved in the construction of this magnificent structure, whose aesthetic appeal makes us forget the technical feat achieved during its construction, with a launching beam specifically built to lay two spans simultaneously.

A new link in Brittany's capital, this second metro line will provide better service for local residents and make life easier for users.

The viaduct in figures :

• 2.4 km long
• 8.6 m wide
• 70 piers
• 1 abutment
• 974 segments
• 34 hyperstatic decks
• 2 isostatic decks
• 70 spans up to 40 m
• Maximum superelevation: 10%

Thank you to SEMTCAR* and Rennes Ville et Métropole for their confidence and congratulations to our teams for the work they have done !
