This bridge replaced the previous 1888 swing bridge.

A view to the northeast of the Jackson Boulevard Bridge over the South Branch of the Chicago River on December 15, 1915, when the bridge construction was nearly complete. The bascule style bridge was built by the Sanitary District (now MWRD) in 1915 and opened to the public in 1916.
The development of the Chicago trunnion bascule bridge occurred during the first three decades of the twentieth century. Despite the controversy over patent infringement — Joseph E. Strauss charged the City of Chicago engineers with infringing on his patented StraussTrunion bascule bridge — the Chicago bascule received great acclaim within the civil engineering profession. The Jackson Boulevard Bridge was completed according to this design. [HAER-data]

The first three loop bridges built by the Sanitary District were "Scherzer rolling lift bridges at Randolph, Dearborn, and State Streets. The Jackson bridge is a trunnion bascule bridge – and of the 18 Loop bridges it is the sole surviving Sanitary District bridge."
It was one of two road bridges in the Loop designed by Joseph Strauss. The other was Lake Shore Drive. The article says he is better known as chief engineer on the Golden Gate Bridge. I also know him as the designer of railroad bridges. See the "bridgeStrauss" label in this blog.

Nice photo. Very cool CONCAVE building facade on right. Some electrical company sign is distance. Enlarged/sharpened/de-shadowed.
[I don't know what he means about a "concave building facade."]

The MWRD built the bascule bridge to replace the previous swing bridge. It was completed in late 1915 and was opened to traffic in January 1916.

Dennis DeBruler The Scherzer rolling lift bridge of the Metropolitan West Elevated is in the background. The Chicago, Aurora & Elgin interurban also used that bridge.

That bridge and the Van Buren Street Bridge were the first two bridges built by Scherzer. He developed this design because there was not enough room between the two bridges for swing bridges. Once again, necessity is the mother of invention.
