The new access bridge to the Séguin Island, an island on the river Seine between Sévres and the commune of Boulogne-Billancourt on the western side of Paris, is a major urban development. A steel structure with a length of 200m, it is a standalone link that has no intermediary support. The platform consists of a 6m carriageway and pavements that vary in length according to pedestrian crossing patterns and periods. As it approaches the Seine, the plateau gets larger to accommodate pedestrians and cyclists that come in from the Cours de l’Ile Seguin and the Quai de Stalingrad.
