Kinzie Street Bridge

The Kinzie Street Bridge is a bridge built in 1909 that spans the Chicago River in downtown Chicago, Illinois, United States. In April 1992, remodeling work on the pilings for the bridge damaged a tunnel located under the Chicago River. The tunnel breach eventually led to the Chicago flood, which flooded the Chicago Loop with an estimated 250 million US gallons (1,000,000 m3) of water. References
