Teton Pass multi-vehicle crash kills 2, injures 4
JACKSON (WNE) —- On Tuesday, two people were killed and four people were injured in a multi-vehicle crash that closed Teton Pass on Highway 22 for most of the day.
The Wyoming Highway Patrol determined in its preliminary investigation that the collision was caused by brake failure of a dump truck full of asphalt coming down the Pass.
Shortly before noon, the eastbound dump truck carrying asphalt lost control and struck a handful of other vehicles above Wilson, WHP Trooper Arron Healy told the News&Guide.
Emergency responders arrived just after noon at the crash site, which was located near the Wyoming Department of Transportation sand shed and Trail Creek Ranch. They found a large section of roadway blocked by multiple disabled passenger vehicles, one overturned dump truck and an asphalt spill from the dump truck.
When the dump truck lost control, it collided with a motorcycle, two pickup trucks, a Subaru and glanced off another vehicle before turning over and coming to a rest on its side, according to the WHP’s preliminary investigation and report. Troopers pointed to the dump truck’s brake failure as a “contributing factor in the collision.”
Two people were declared dead at the scene.
David Page, 57, of Mammoth Lakes, Calif., was killed along with his dog in the car, according to the Teton County Coroner’s Office.
Nicholas “Nick” Besobrasow, 66, of Tetonia, Idaho, was the other victim.
First responders transported four other patients with “minor and moderate injuries” to St. John’s Health, according to Jackson Hole Fire/EMS Chief Mike Moyer and WHP. Law enforcement and emergency service providers had not released the injured motorists’ identities by press time Tuesday.
Traffic came to a standstill quickly in the early afternoon and commuters headed back to Idaho from Jackson were turned around and detoured through Alpine. Due to construction on Highway 26 between Alpine and Swan Valley, cars were backed up on the detour during the evening commuter hours.
Highway 22 was still closed as of the 9:30 p.m. press time Tuesday.
