GLENHAVEN – A single-vehicle collision on Highway 20 Wednesday morning sent a Sutter woman to the hospital with major injuries.

A report from California Highway Patrol Officer Josh Dye reported that Sidne Allread, 63, received multiple fractures and a major head injury as a result of the crash, which occurred at about 10:30 a.m. on Highway 20 west of Bruner Drive.

Allread was driving her 2003 Mazda Protege westbound on Highway 20 at an unknown speed, said Dye, who added there were not witnesses to the incident.

For reasons that aren't known, Allread's vehicle went off the road to the north and went up a steep cutbank, where it hit a mass of rocks, according to Dye's report.

The car then rolled over onto its roof in the westbound lane, Dye reported.

Allread, who was alone in the car, was wearing her seat belt, but received major injuries and didn't regain consciousness before being flown by REACH helicopter to Santa Rosa Memorial Hospital for treatment.

No further information about Allread's condition was available Wednesday afternoon.
