Passerelle de Meylan, Cable-stayed footbridge and cycle bridge in Saint-Martin-d'Hères, France

The Passerelle de Meylan is a reinforced concrete footbridge with a triangular deck supported by two inverted Y-shaped pylons. It spans about 126 meters and connects Saint-Martin-d'Hères with the neighboring town of Meylan.

Approved by ministerial decision on 1 April 1977 and finished in 1980, the footbridge was built by Campenon-Bernard to a design involving Michel Virlogeux, with the cable-stayed variant proposed by Michel Placidi. It replaced a detour via the Sablons and RN 90d bridges, which were reserved for motor traffic. The two half-spans were concreted on land and rotated into place over the Isère.

Locals call it Passerelle de l'île d'Amour after the park it leads into on the Meylan bank. It was built for pedestrians and cyclists crossing the Isère between Saint-Martin-d'Hères and Meylan, and it feeds into the Grenoble university domain along the river.

The bridge provides a smooth path for both pedestrians and cyclists without major inclines or stairs. It is helpful to expect more people using it during peak hours and good weather.

The deck was built in two cable-stayed half-spans cast on falsework parallel to the banks, then rotated over the Isère and joined by a closure joint before final prestressing. Engineer Michel Placidi proposed this variant, which avoided a pier in the river's unpredictable current; Campenon-Bernard carried out the work.
