viaduc de Longeray
Longeray viaduct is a railway bridge from the Longeray-Léaz line to the Bouveret which crosses the Rhône at the exit of the Longeray-Léaz station. It is located in the hamlet of Longeray on the territory of the commune of Léaz, in the department of Ain in the region Auvergne-Rhône-Alpes. Two viaducts followed each other.
The first was built in 1879 and destroyed by the French army in 1940. Reconstructed at the same location, the new viaduct was commissioned in 1943.
