UPDATE 8/16/ 11:31 p.m.

COTTONWOOD HEIGHTS, Utah (ABC4) — Cottonwood Heights Police and Unified Fire have extricated an adult female victim from her car after she was trapped for over an hour due to a major crash off southbound I-215 and Highland Dr.

Around 8:45 p.m., a white truck was traveling northbound on Highland Dr. approaching the I-215 overpass when police say it crossed into the southbound lanes and hit two vehicles on the off-ramp. The truck came to rest on top of a red sedan trapping the female driver inside her vehicle.

In what CHPD Sgt. Gary Young called a “herculean effort,” Unified Fire authorities worked for over an hour to rescue the driver by cutting small pieces off the vehicles until they were able to extricate her. She was then transported to Intermountain Medical Center in extremely critical condition.

The Cottonwood Heights Major Crash Team will be investigating the cause of the crash. There is no indication at this time that intoxication was a factor in the crash, according to Young.

The driver of the truck, who received a minor laceration on his face, is conscious and cooperating with police in the investigation. Smith said passengers of the other vehicle involved will be driving themselves to the hospital to receive care. None of the vehicles are operable.

The roads are expected to fully open in the next couple of hours as police clear the road and finish gathering information for their investigation, according to Young.

The woman’s current condition and projected recovery are not known. There have not been any fatalities at this time.

UPDATE 8/16 10:38 p.m.: The female has been extricated from the vehicle after about an hour of rescue efforts. She is currently in extremely critical condition. There are no current fatalities or other injuries reported, according to Cottonwood Heights Police.
