Location

The Cize–Bolozon viaduct is a combination rail and vehicular viaduct crossing the Ain gorge in France. It is a structure that connects the communes of Cize and Bolozon in the Ain département.[1][2]

In 1875, an original span built in the same location but was destroyed later in World War II.[3][4] The viaduct was reconstructed as an urgent post-war project due to its position on a main line to Paris.[5] It reopened in May 1950.[1]

It has two different levels: the upper level is a railway while the lower carries road traffic. The railway was closed for reinforcement and restoration in 2005, and reopened in December 2010 as part of the Ligne du Haut-Bugey.[6][7][8] The lower level is a local road from Poncin to Thoirette.
