Kinzie Street Bridge

The Kinzie Street Bridge is a single-leaf bascule bridge built in 1909 that spans the Chicago River in downtown Chicago, Illinois, United States.

Incidents
In April 1992, rehabilitation work on the pilings for the bridge damaged a freight tunnel located under the Chicago River. The tunnel breach eventually led to the Chicago flood, which flooded the Chicago Loop with an estimated 250 e6USgal of water.

In August 2004, a Dave Matthews Band tour bus passing over the bridge dumped 800 pounds of human waste through the open metal grate bridge deck into the Chicago River. The waste landed on an architecture tour cruise boat and passengers passing under the bridge at that time.
