The Cize–Bolozon viaduct is a combination rail and vehicular viaduct crossing the Ain gorge in France connecting the communes of Cize and Bolozon.^[1][2]

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

It carries road and rail traffic at different levels: the railway, which was closed for reinforcement and restoration in 2005, occupies the upper level. Part of the Ligne du Haut-Bugey,^[6][7] it reopened in December 2010^[8] as part of the international Paris–Geneva line. The local road from Poncin to Thoirette uses the lower level.
