Four people were injured in two separate crashes Saturday morning on Interstate 94 near Chatham on the South Side, according to Illinois State police.
About 1:10 a.m. Illinois State police responded to the southbound lanes of the Dan Ryan near 67th Street, where a vehicle had struck the left concrete median and burst into flames.
One person was taken to a hospital with injuries that aren’t considered life threatening, state police said.
About an hour and a half later, state police responded to a second crash in the northbound lanes of the Dan Ryan near 75th Street, involving four vehicles, state police said.
Troopers determined that at about 2:40 a.m. the front end of a commercial truck struck the rear passenger side of a second commercial truck, causing it to lose control, state police said. The first commercial truck continued forward, struck a car and caught on fire.
The second commercial truck struck the left concrete median of the expressway and was struck by a fourth vehicle, state police said.
Three people from the crash were taken to a hospital with non-life threatening injuries, state police said.
