From the Washington State Department of Transportation: 

Near Cle Elum, drivers will experience delays due to single lane closures in both directions 24/7 through October. Crews will adjust the detour to facilitate heavier traffic on the weekends. The westbound off-ramp to Cle Elum and Wenatchee at exit 85 is closed to traffic through Thursday, Oct. 8. A detour will be in place to direct traffic to the next westbound off-ramp at exit 84. This project improves three miles of pavement on westbound I-90 in the Cle Elum area.

Drivers will also see delays across the Vantage Bridge due to a single lane eastbound closure, which is in effect 24 hours a day, 7 days a week until this fall.

Drivers are encouraged to use the following tools to plan their trips over I-90:
