A 56-year-old Sammamish woman was cut out of her vehicle and airlifted to Harborview Medical Center in Seattle after a head-on traffic accident Sunday night on Northeast Novelty Hill Road in unincorporated King County near Redmond.

The accident appears to have been caused by an alcohol-impaired driver, according to Sgt. John Urquhart, spokesman for the King County Sheriff’s Office.

A 2002 Jeep Liberty, driven by a 25-year-old Portland woman, was traveling westbound on Northeast Novelty Hill Road, crossed the center lane and struck the left front corner of an on-coming 2004 Lexus E330, driven by the Sammamish woman. After the collision, the Jeep rolled over on its top and landed in the westbound lane.

Fire crews had to cut up the car to get the Sammamish woman out before she was airlifted to Harborview.

“Alcohol appears to be a contributing factor on the part of the Jeep driver,” Urquhart said. His office is investigating and no arrests had been made as of press time.
