Why Was the Chicago River Disappearing Beneath Downtown?

On April 13, 1992, the Chicago flood paralyzed the city. Why did the warning signs go ignored for eleven days? On that day, the Chicago River began draining into the city's streets, creating a massive whirlpool near the Kinzie Street Bridge. The water surged through an abandoned network of underground tunnels, flooding basements, disrupting critical utility services, and forcing the evacuation of 200,000 people from the downtown loop. This documentary examines the failure of the forgotten freight railway system and the specific damage beneath the river that made the disaster possible. We trace the timeline of the chief bridge inspector’s urgent warning issued eleven days before the collapse, analyzing the engineering disaster that nearly crippled the city’s core.
