Rouen, France - How to conceive a lift bridge which reconciles road and river traffic? To tackle this challenge, a multidisciplinary team of engineers and architects collaborated intensively. The result is an elegant and light structure combining efficiency and simplicity. The innovative and ingenious butterfly-shaped, cross-leveraged system marks the skyline of the historic town of Rouen.

This 600 m long structure is the central part of a 4 km long urban artery linking two motorways in the north and south of the Rouen area, and crossing the Seine River approximately 2 km downstream from the historical town center of Rouen. The structure comprises a main 120 m lifting span allowing a maritime traffic clearance 86 m wide and 55 m high, and two approach viaducts, with a total length of 600m. It is divided in two decks, each one carrying a 3-lane roadway and a pedestrian way. The main lifting span is made entirely of steel (total weight: 1300 tonnes per deck), and the approach viaducts of composite steel and concrete.
Arcadis was in charge of the architectural and structural design. We led a team consisting of architect Aymeric Zublena, special consultant Michel Virlogeux, and specialized consultants firms Eurodim and Serf. Additionally, Arcadis provided assistance during the tendering procedure and technical support during the construction.
