Two people were injured -- one critically -- and the lanes of the Chinatown feeder ramp on Interstate 90/94 were closed Friday morning after a vehicle rolled over.
The single-vehicle crash was reported about 4:10 a.m., according to Illinois State Police.
The driver of the vehicle, a woman whose age was not immediately known, was taken in critical condition to Northwestern Memorial Hospital, police said.
A female passenger in the vehicle was taken with non-life-threatening injuries to John H. Stroger Jr. Hospital of Cook County, police said.
Traffic was diverted to Interstate 55 -- the Stevenson Expressway -- while crews worked to clear all four lanes, police said.
Police remained at the scene of the crash as of 7:30 a.m.
