POTLATCH — A 45-year-old Pullman woman died Tuesday during a two-vehicle crash on U.S. Highway 95 north of Potlatch.

Additionally, a 31-year-old man from Toledo, Ohio, was taken via air ambulance to a local hospital after sustaining critical injuries, according to a news release by the Idaho State Police distributed Tuesday afternoon.

The crash occurred around 11 a.m. Tuesday when a smaller vehicle was involved in a head-on collision with a semitruck, according to the news release.

The Pullman woman driving a Ford Escape was critically injured and died at the scene. The Ohio man driving a Volvo tractor trailer was critically injured during the collision, according to the news release.

The drivers were the sole occupants of the vehicles.

An Idaho State Police dispatcher said the semitruck had caught fire during the incident, which melted the trailer.

Traffic on the highway was blocked in both directions for four hours to allow emergency responders to assist those involved, according to the news release. The highway has since reopened to single-lane travel to allow traffic to pass.

The incident remains under investigation by the Idaho State Police, according to the news release.
