Abstract: A UHPFRC footbridge has been built by Eiffage Infrastructures in le Cannet des Maures southern France, that crosses a railway line. Its design is remarkable for its purity. The U-shaped deck cross-section needed no added superstructure or equipment once precast, since the UHPFRC could fulfill all the requirements on its own, from assuming the shape of a parapet to being slightly textured to prevent slipping on the deck floor. The Cannet des Maures footbridge is also innovative due to its construction method. The segments were precast round 650 km away from the site, and then transported to an assembly area located nearby the final footbridge position. The deck was there fully assembled on a temporary structure, and prestressed, to become a 84 tons monolithic package that was carried out onto its definitive supports by a 750 tons mobile crane. The whole point of this construction sequence was to fit in the short time-frame of traffic interruption set by the French national railway operator SNCF.
