Nestled in a spectacular natural setting, the viaduct offers superb viewpoints over the Ain gorges. Built at the beginning of the 20th century and then rebuilt after the Second World War in 1950, it illustrates the railway and road heritage of the territory.

pretty little stone viaduct with 2 superimposed lanes, one for cars with 6 arches and one for the train with 11 arches. Atypical.

Beautiful paved road, but for those who prefer dirt tracks, cross to the other side of the river! There won't be any cars and the views are even more beautiful.
