The cable-stayed metallic structure measures 720 m and, including the access viaducts, represents a total length of 3 356 m. The bridge was commissioned on 18 October 1975, after three years of construction.

In 1992, the Loire-Atlantique general council took over the Saint-Nazaire SAEM, the contractor for the creation and operation of the bridge.

The building was returned to the department's general council road heritage organization, which has been responsible for its management and maintenance since 1 August 1995.

In fact, it is a requirement from the state since the traffic code mandates white markings on the ground.

The only regular coach lines using the bridge and providing intercity connections between Saint-Nazaire and the Pays de Retz region are those of the Lila network (routes 15, 16 and 17).
