A woman had to be flown to the hospital after a single-car crash on westbound Interstate 80 Wednesday evening.

About 7:20 p.m., the woman swerved near 6650 East and drove her Jeep Liberty off the freeway, said Utah Highway Patrol trooper Cameron Roden.

The vehicle hit a tree, causing the vehicle to roll several times down a hill.

Police extricated the woman, who was around 20, from the car and flew her to a nearby hospital. Roden said the woman's injuries were serious, but not life-threatening.

Officials still are trying to determine what caused the crash.
