This is the latest for Washington state Department of Transportation:

I-90 travelers, major heads up! A collision involving a semi is blocking both eastbound lanes and one westbound lane at milepost 93 near Elk Heights Road, about 13 miles west of Ellensburg. Eastbound traffic is being diverted to SR 970 on to US 97 or SR 10, about a 30-minute detour. The estimate. ...again, just an ESTIMATE. to reopen the lanes at about 10:30 a.m. There is heavy congestion already so if possible delay your trips or consider alternate routes!
