The project consists of a new development and the revaluation of the Lion Bridge in Saint Genis Pouilly near the CERN. The existing bridge spans over the river Lion. It allows road traffic at the entrance of the agglomeration. The approximate width of the carriageway is 7 m and the span of the bridge is 17.5 m. A survey report provided of a detailed study of the existing structure. Continuing the re-qualification of the Rue de Genève and downtown Saint- Genis-Pouilly, it aims at redefining the bridge without changing the current structure to allow a new intervention. The project allows road traffic at the entrance to the town and improves pedestrian traffic by about 2.20 m at the bridge approaches, which is currently reduced to about 1 m.
The requalification of the Lion Bridge responds to its relatively high traffic and the difficulties of access for pedestrians and disable. The project also highlights the question of integrating this infrastructure element into its landscape, in this case along the river and its landscaped accesses along the entire route along the river.
