Viaduc de Longeray, Railway bridge in Léaz and Clarafond-Arcine, France
The Viaduc de Longeray is a railway bridge made of reinforced concrete that spans across the valley with its distinctive structural design. The bridge consists of several spans of varying sizes arranged across the landscape.
The bridge was built between 1941 and 1943 by engineers R. Breiffel, G. Le Marec, and Medotte to replace an older steel structure. Its predecessor was destroyed in 1940, making this new construction necessary.
The structure takes its name from the nearby village of Longeray and has shaped the regional landscape since its completion. Visitors can observe how this crossing point links communities and remains part of the daily life of the area.
The structure can be viewed well from nearby vantage points along the rail corridor and surrounding areas. It is recommended to visit at different times of day to see how light changes the appearance of the concrete structure.
French authorities recognized the engineering achievement of this structure by designating it as Heritage of the 20th Century. This distinction honors the monument's importance in the history of French railway infrastructure.
