One lane of I-55 northbound is open again between Bluff Road and U-S Route 6, several hours after a handful of accidents injured at least seven people Monday morning, on Interstate 55 in Will County.
Illinois State Police say the crashes involved semi-trucks and passenger vehicles, and took place between 8:30 and 9 a.m.
Two cars were pinned beneath semis.
A number of people were transported to Saint Joseph Medical Center in Joliet.
State police could not provide details about the nature of the injuries.
A state police spokesman says the interstate’s closure backed up traffic for at least 15 miles.
