Crews will continue to chip away at the rock slopes along Interstate 90 east of Snoqualmie Pass with more rock blasting this week. Drivers should plan for an hour of added travel time.

The Washington State Department of Transportation (WSDOT) and contractor crews will close I-90 in both directions from Hyak (milepost 54) to the Price Creek Sno-Park (milepost 61) from 7 p.m. to 8 p.m., Thursday, May 10. This work is weather dependent and is subject to change.

Rock blasting is part of the $551 million I-90 Snoqualmie Pass East-Hyak to Keechelus Dam project to widen a five-mile stretch of the highway from four to six lanes and improve reliability and safety. This multi-year project is funded by the 2005 gas tax and is scheduled to be complete in 2017.

Only three weeks remain of daytime lane closures near Easton. After Memorial Day weekend, crews will switch to night work to complete the I-90 Lake Easton to Big Creek Project.

Drivers need to plan for delays on I-90 Monday through Friday mornings, due to daytime single-lane closures in both directions. To improve weekend traffic flow, crews will open two eastbound lanes and one westbound lane from 9 a.m. Fridays to 9 a.m. Sundays. And on Sundays, crews will open two westbound lanes and one eastbound lane from 9 a.m. to 9 p.m.
