UPDATE, 9:30 p.m.:

CHAMPAIGN — One person is dead and another is in critical condition following a single-vehicle rollover crash on Interstate 72 just west of Champaign.

Illinois State Police reconstruction officers remained at the scene of the crash, which took place at 3:53 p.m. Tuesday at milepost 179, near Rising Road.

State Trooper Tracy Lillard said that a 17-year-old Monticello female who was behind the wheel of a silver 2005 Scion died after being transported to an area hospital.

Her passenger, a 20-year-old Allerton man, was also taken to an local hospital, where he remained in critical condition Tuesday night.

According to a police report, the car was headed east on I-72 when it left the highway and hit the eastbound guardrail at the Rising Road overpass.

The vehicle crossed the center median, moved across all of the westbound lanes and smashed into the westbound guardrail on the north side of the shoulder of I-72.

The car then rolled over multiple times, ejecting the Allerton man and partially ejecting the Monticello teen.

Interstate 72 was closed for nearly four hours on Tuesday to allow police to do crash-reconstruction work, Lillard said.

Police said both the driver and passenger presumably were not wearing seat belts.

I-72 remained closed until about 7:45 p.m.
