Construction It was built by Entreprise GTM, with construction starting in 1958.Technical description of the bridge It was built with the balanced cantilever, or free cantilever, method, and mobile cantilever scaffolding. The reservoir (retenue du barrage) began construction in 1955 and was finished in June 1960.
The bridge was built before the valley had been flooded, and the concrete piers are much higher than they may look.
Structure It is situated in the Hautes-Alpes department in the Provence-Alpes-Côte d'Azur region in the far east of southern France. It crosses the Lac de Serre-Ponçon, an artificial lake or reservoir. The creation of the lake prompted the 1958 film, Girl and the River. It carries the N94 (Route Nationale RN 94) road.
