Location

The bridge raised for sailboats

Great Lakes Dredge and Dock Company was the contractor for the substructure, and the Ketler–Elliot Company was the contractor for the superstructure. Original electrical equipment was installed by C. H. Norwood. The bridge is an example of a trunnion bascule bridge, with each half of the roadway is cantilevered out from shore abutments. The bridge is extremely efficient to operate.

The bridge provided a new connection to the southern banks of the river and aided in westward expansion along Wacker Drive.
