A 10-vehicle collision along Interstate 90 seven miles east of Ritzville has shut down both westbound lanes.
The accident happened at 12:46 p.m. near milepost 229 in Adams County.
One person who suffered life-threatening injuries in the collision was transported to the hospital in Ritzville later died. An initial WSP release indicated two people had died in the collision.
Dozens of vehicles are stuck along the roadway at the crash site. It's not clear how many were involved in the collision or were damaged, but many of them are not being allowed to leave because they were involved in the fatal collision and are part of the crash investigation.
Also hampering the reopening of the roadway is the fact that semi trucks cannot turn around, which is making it difficult to get any of the vehicles not involved in the collision turned around.
The State Patrol is detouring people off I-90 at the Tokio exit, but the freeway is backed up for several miles.
There's no estimate on when the freeway will reopen.
At the time of the crash the area was under a winter weather advisory for snow accumulations of one to three inches through 7 p.m. Friday. The Washington State Department of Transportation is reporting there is compact snow and ice on Interstate 90 from the Grant/Adams County line all the way to the Cheney /Four Lakes exit.
