More than 20 vehicles wrecked after blowing dust and ash made it hard to see. Multiple injuries were reported.
Lanes in both directions were closed at one point. Westbound lanes were eventually reopened, but eastbound is still closed at mile 115.
That's just past the turnoff to go to Yakima if you continued east on I-90 toward Spokane. The detour to get around the closure is the Old Vantage Highway.
