The Lucie-BréardFootbridge Renovation
A great example of eco-responsible infrastructure reuse
Project Stakes
Built about fifteen years ago, this swing bridge located in Saint-Denis in the Paris suburbs originally allowed cars to travel from the Francs-Moisins district to the Stade de France. Although equipped with a fixed footbridge for pedestrian crossing when the bridge was closed, it remained inaccessible to people with reduced mobility (PRM) and cyclists. Regularly broken down due to its obsolescence, the footbridge was no longer functioning and constituted a real obstacle for local residents wanting to cross the canal.
Driven by the Paris 2024 Olympics, the municipality launched a comprehensive urban renovation project for the district, including the rehabilitation of this footbridge. For the city of Saint-Denis, this eco-responsible project to repurpose the existing road infrastructure to promote soft mobility addresses several strategic challenges:
- Energy challenge: decarbonize the site by reusing existing infrastructure
- Social challenge: open up an underprivileged neighborhood and energize the city
- Accessibility challenge: provide access for pedestrians, cyclists, and PRM
- Heritage challenge: preserve and sustain the historical urban landscape

Eiffage Metal's Scope in the Project
Launched in January 2023, the major challenge of this circular economy project is to reuse the deck of the former mobile bridge to create the new canal crossing.
Eiffage Metal carried out execution studies, manufacturing at the Lauterbourg plant, and assembly of 2 metal access ramps over 100 meters long each, as well as 2 staircases on either side of the deck. The main operation involved sliding the rehabilitated deck on barges and hoisting it onto newly constructed piers.
Additionally, Eiffage Metal also manufactured and installed railings with integrated lighting, anti-slip protective resin, small locksmith work, concrete stair steps, and dynamic dampers to limit vibrations when crossing the structure.
