Southbound lanes on Interstate 57 were closed Friday morning at 127th Street after a fatal crash in south suburban Calumet Park.
A 2016 white Dodge sedan struck the back of a silver-colored 1999 Jeep SUV about 2:06 a.m. in the southbound express lanes near 127th Street, Illinois State Police said.
The Jeep went off the road, rolled over a concrete barrier and caught fire on railroad tracks below, state police said. The driver was pronounced dead at the scene.
A 25-year-old man who was driving the Dodge was taken to a hospital “with no significant injury,” state police said.
Investigators believe the crash was alcohol-related, state police said.
The Jeep’s driver was identified by the Cook County medical examiner’s office as 39-year-old Stephanie V. Anselmo. An autopsy Saturday said she died of multiple injuries related to the crash. Her death was ruled an accident.
The southbound lanes were closed from 127th Street to 147th Street as authorities continue to investigate, state police said.
