A Springville woman went to the hospital with what authorities said are life threatening injuries following a single vehicle crash Wednesday evening.
The Linn County Sheriff's Office said it happened about 5 p.m. at County Home Road and Jordans Grove Road, about 5 miles northwest of Springville.
Deputies said 61-year-old Melissa Davidson was eastbound on County Home Road when she lost control of her vehicle and entered the north ditch just west of Jordans Grove Road. The vehicle rolled several times, stopping on its side.
An air ambulance flew Davidson to University of Iowa Hospitals and Clinics.
Deputies said Davidson was not wearing a seatbelt at the time of the crash.
