The Otranto Bridge was located northwest of St. Ansgar, Iowa, United States. It carried traffic on 480th Avenue over the Cedar River for 170 feet (52 m). The supervisors from Mitchell County contracted with the Chicago Bridge and Iron Company (CBI) to build two bridges in the county. Chicago engineer Horace E. Horton from CBI designed this Camelback through truss bridge. It replaced and older span at the same location, and it was completed in 1899 for $3,257. The Otranto Bridge was one of the few Camelback through truss bridges built in Iowa. It was replaced by a modern bridge and was privately owned before being dismantled.
