Chanteloube Bridge

This is one of the main engineering structures built as part of the project to build a railway line from Grenoble to Bercelonnette.
Begun in 1910, the project was finally halted in 1934 in favour of the Veynes/Briançon line.
Since the construction of the Serre-Ponçon dam, the Chanteloube viaduct is out of water when the lake level reaches 772 metres.
