A car crossed the center line and collided with a semi truck near Potlatch State Park just after noon, said Russ Winger with the Washington State Patrol.
The two people in the car were pronounced dead at the scene. The semi truck driver was not hurt.
Winger says the Department of Ecology team was on the scene to take care of a minor diesel spill.
Winger didn't have any further details on the fatalities or what caused the crash.
