Crews are shutting down I-90 starting at 7 p.m. Monday for rock blasting from Gold Creek to Easton.
The timing for when the area reopens depends on how fast crews can remove all the debris, officials said. WSDOT is warning drivers to plan for an extra fours hours of travel time.
More rock blasting closures are planned this week from 7 to 8 p.m. Tuesday, Wednesday and Thursday from Gold Creek to the Price Creek Sno-Park.
