A three-vehicle crash Saturday afternoon on U.S. Highway 97 sent eight people to the hospital, including one man who suffered critical injuries.

The crash at about 3 p.m. shut down the highway in both directions for roughly two hours, and traffic backed up for seven miles, according to news releases from the Oregon Department of Transportation and the Oregon State Police.

At 3:10 p.m., Stacy Cordaway, 48, of Shingle Springs, Calif., was driving north in a 2006 Nissan truck when she lost control and slid sideways into the southbound lane, according to police. Cordaway’s truck collided with a 1986 Suzuki sport utility vehicle driven by Herbert Kroshel, 41, of Salem.

The collision caused Kroshel’s Suzuki to go over a guardrail and down an embankment, while the Nissan hit a southbound 2006 Suzuki Samari sport utility vehicle driven by Leland Wilson, 55, of Tigard, according to the police.

Some of the people involved in the wreck were trapped inside their vehicles until emergency workers responded, according to the fire department.

At the time of the crash, it was snowing and the highway was covered with ice and snow, according to a news release from the Sunriver Service District Fire Department.

Kroshel suffered critical injuries and was taken by ambulance to St. Charles Bend. Kroshel was still listed in critical condition Sunday evening.

The other seven people involved in the collision were also taken to St. Charles Bend, with non-life-threatening injuries, according to the police.
