SEATTLE -- A 20-mile stretch of Interstate 90 was closed for several hours near Cle Elum after a deadly crash between a semi tanker and car Wednesday morning, leaking ammonia and propane that prompted nearby evacuations.
Washington Department of Transportation officials reopened eastbound I-90 around 2:20 p.m. Westbound I-90 remained closed as crews continued to investigate and clear the scene, until late Wednesday evening.
The crash happened Wednesday morning at milepost 85.5 just east of Cle Elum, closing both directions of traffic.
The ammonia and propane leak prompted nearby evacuations and a shelter-in-place. Residents one mile downwind from the crash were told to close their windows and turn off their heating and air conditioning. Crews capped the leak and the evacuations and shelter-in-place were lifted, allowing residents to return to their homes.
Westbound traffic was stopped at mile post 106 in Ellensburg; those lanes reopened Wednesday afternoon. Eastbound was closed at mile post 84 near Cle Elum.
