Four people were taken to a hospital Sunday after a six-vehicle crash on the Tri-State Tollway in Gurnee, authorities said.
The crash happened about 12:30 p.m. on the northbound side of the highway at Route 120. It started when the driver of a Ford Mustang in the far left lane swerved and hit a Toyota pickup truck in that lane and a Ford Focus in the next lane, Illinois State Police Master Sgt. Will Rogers said.
The Focus then hit a Lexus, which hit a Cadillac, which hit a Hyundai, Rogers said.
Three lanes and a shoulder were temporarily shut down. Combined with a pre-existing traffic jam prompted by people driving to Six Flags Great America, cars were backed up for miles, authorities said.
Twelve people were in the six cars, but not all needed to be taken to the hospital, Gurnee Fire Lt. David Douglass said. Those that did were sent to Advocate Condell Medical Center in Libertyville.
None of the injuries was believed to be life threatening. Most were caused by air bags or seat belts, Douglass said.
Firefighters from Grayslake and Libertyville assisted on the scene.
The accident remained under investigation Sunday afternoon. No information was available about potential tickets.
