Savines Bridge, Concrete viaduct in Savines-le-Lac, France.

Savines Bridge is a 924-metre concrete box-girder viaduct over Lac de Serre-Ponçon, carrying the N94 road. It rests on twelve 77-metre spans supported by square concrete piers 5 metres wide with 0.40-metre-thick walls. The flat deck has metal railings and is crossed by cars and trucks.

Construction of the Savines Bridge began in 1958 under the firm Entreprise GTM, using the balanced cantilever method with mobile scaffolding. It was designed by Jean Courbon of the SEEE and was among France's first post-tensioned prestressed concrete bridges. The bridge was finished in 1960, before the Durance valley was flooded; the second village of Savines, dating from the 1820s, was submerged on 3 May 1961.

The creation of Serre-Ponçon Lake prompted the 1958 film 'Girl and the River', set in the valley before it was flooded. The bridge, finished in 1960, crosses the water that submerged the old village of Savines on 3 May 1961. The commune later took the name Savines-le-Lac.

The bridge sits about 50 meters above the water and is part of Route Nationale N94, serving as a regular vehicle crossing. You can drive across it or view it from the surrounding shores.

The bridge was finished in 1960, before the valley was flooded, so its piers stood on dry land and are taller than they appear from the deck. The old village of Savines, dating from around 1825, lies 40 metres beneath the water.
