Abstract: The Lez in Montpellier is a surprising river. It remains very quiet and almost dry the most of the time. But each year, in a very few hours, the flood can suddenly reach a 10 m height. These dangerous floods frequently cause large damages over the river side. Thus, when the city council and the SERM decided to launch the competition for a 75 m long road bridge in 2010, a long span bridge with no support in the river was expected: suspension bridge, truss girders, bow string etc… In order to avoid these kinds of emphatic superstructures in the sweet landscape of Montpellier, architect and engineers proposed an innovative bridge all made with UHPFRC. This material provided a design with very thin piers and a slender deck, in order to obtain a perfect hydraulic transparency and a lighter impact on ground foundations. At the same time, the working time on site between two floods was drastically reduced. A special formulation of white UHPFRC using stainless fibres was developed for this project. At the end, the bridge was built by the firm Fondeville in 4 months, with a restricted budget and a better sustainability.
