An impressive work that has its Wikipedia page https://fr.wikipedia.org/wiki/Viaduc_de_Cize-Bolozon

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