The south Harlem Avenue Bridge is a pair of bascule bridges over the Sanitary and Ship Canal located in Chicago between the Stevenson Expressway Bridge and the Santa Fe Railroad Bridge over the Sanitary and Ship Canal. The northbound span was built in 1931; southbound in 1966. The spans appear similar. The main differences are the lack of V lacing on the built up beams of the newer structure and the oval cut outs on the newer structure.
The bridge design is unique in that it is a Warren deck truss. Total length is 456 feet. Roadway width is 56 feet. Bridge is open but it is fixed. Inspection as of 7/2012. Deck Condition 6 out of 9 Satisfactory; Superstructure Condition 5 out of 9 Fair; Sub structure Condition 6 out of 9 Satisfactory.
