The Illinois State Police say a semi-truck driver went off the west edge of the Sixth Stree exit ramp off of Interstate 55/72, flipping his semi on its top. The trailer split open spilling numerous boxes of household chemicals into the grass. Chemicals like Drano, Windex and Raid. The State Police were able to keep the exit ramp open while the mess was cleaned up. The driver of the semi, 46-year-old Robert Chambers of Kenosha, Wisconsin was taken to the hospital for minor injuries.
