The Summit County Coroner’s Office has identified the woman who died in a single-vehicle car crash on Colorado Highway 9 north of Silverthorne on Monday, Feb. 26.

Gwyneth Williams, 19, of Denver, died in the crash, Summit County Coroner Amber Flenniken said. The crash, which occurred around 9:40 a.m., closed the highway for about four hours that day.

Colorado State Patrol Trooper Jeanne Rahe said Williams was driving a white Subaru Crosstrek southbound on the highway when she went off the right side of the roadway near mile marker 115.

The front side of the vehicle collided into multiple trees before the vehicle went airborne, rotating clockwise, before coming to a final rest up against a tree, she said.

Williams was wearing a seatbelt at the time of the crash, Rahe said. Medical personnel reportedly declared Williams dead at the scene.
