The accident happened last Saturday.
Peoria County Coroner Johnna Ingersoll says 46-year-old Roberta Hadsall died in the hospital today.
Authorities say Hadsall was driving her Ford Explorer, going west-bound after 9 PM Saturday night in Peoria County.
That's when an oncoming vehicle crossed the center line at Lancaster Road and Croy Lane.
The vehicle hit Hadsall's SUV head on.
Hadsall's husband was a passenger in the SUV.
Roberta was wearing a seat-belt.
She passed away at OSF St. Francis medical center just after 12:30 this afternoon.
