| Abstract: |
With a total length of about 210 m, the new Lannion downstream bridge will cross the river with an “S” shape path. Deck will be made up of a steel and concrete composite box girder. To reduce impacts on the river flow, only a pier will be placed in the riverbed. It consists of a steel tetrapod formed by four legs, embedded on the bottom plate of the box and designed as extensions of box’s webs. Crutches meet on a metal base resting on a reinforced concrete pier. The architectural design consists of a light structure characterized by natural and maritime shapes: an homage to the site’s history and landscape. |
