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.

A view from the Jackson Street bridge looking south towards Van Buren on September 5, 1903, showing an area adjacent to and above the bypass channel on the South Branch of the Chicago River. The Sanitary District (now MWRD) developed a plan in 1895 to increase the capacity of the South Branch in order to convey necessary flow of water for the Chicago Sanitary and Ship Canal. The MWRD deepened and widened the waterway by dredging and replacing docks and bridges, and where bridge replacement was not feasible (roughly between Van Buren and Adams) the MWRD built a by-pass channel. Construction of the bypass channel began in 1898 and it opened in 1900. It was removed beginning in 1911 after adjoining property was acquired, allowing for widening of the river in the area.
