A view to the south from the Adams Street bridge on May 10, 1904, showing the Pennsylvania Railroad tracks and warehouse on the west side of the South Branch of the Chicago River, with the Jackson Street and Metropolitan West Side elevated railroad bridges visible in the background. The inlet to the bypass tunnel, which had been built by the Sanitary District (now MWRD) to accommodate increased flow of water through the Chicago River to the Chicago Sanitary and Ship Canal, is at left below the railing.

The cofferdam on the west side of the South Branch of the Chicago River during construction of the Jackson Boulevard Bridge in Chicago, Illinois, on April 2, 1914. 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.
