Cize–Bolozon viaduct is located in the north east of Lyon, France, crossing Ain gorge. The bridge has two levels, the railway is on the upper level which is the part of international Paris–Geneva line, and the local road uses lower level. It was once constructed in 1875, but destroyed during WW2, reconstructed in 1950.
