Scene of the accident

City workers and officials stand by as a crane pours gravel into the Chicago River near the Kinzie Street Bridge in an attempt to plug a hole in a freight tunnel that runs under the river. By some accounts, the hole was 20 feet wide. It took days before the Kenny Construction company was able to control the leak by drilling shafts into the tunnel where the flood had begun and placing emergency plugs inside.
