Canal Street Railroad Bridge
The Canal Street railroad bridge is a two-track vertical lift bridge across the South Branch of the Chicago River. It was built as Pennsylvania Lift Bridge No. 458 for the Pennsylvania Railroad in 1914 on a design by the firm of Waddell and Harrington. The main span is 273 feet long and can be lifted on two 185-foot towers to a height 130 feet above the river. The main span is balanced by two 179-ton counterweights. It was designated a Chicago Landmark in 2007 and is owned by Amtrak. ( Journal of the Western Society of Engineers, 1915, Volume 20, HistoricBridges.org
