A man was taken to Javon Bea Hospital in Rockford following a Sunday-morning crash on Interstate 90 near Huntley.
Illinois State Police said the crash happened about 10:43 a.m. Sunday at mile marker 46, which is just west of the Route 47 interchange in Huntley. The man was traveling west on Interstate 90.
ISP said a silver Volkswagen hatchback left the road, hit a guardrail and rolled over. The driver was taken to Javon Bea with injuries serious enough to go to a Level 1 trauma center, Batallion Chief Brian Harders of the Huntley Fire Protection District said.
Harders said the man was going to be flown but the arrival time of the helicopter was 25 minutes, and the hospital was a 25-minute drive.
The driver was the only person in the car, and the crash is under investigation, according to the ISP.
