Eastbound I-90 from Seattle to Mercer Island will be reduced to two lanes starting at 10:00pm this Friday, December 15, until 6:00am Saturday, December 16. The two right lanes will close, and several ramps will be impacted: from 9:00pm Friday until 6:00am Saturday, the on-ramp from northbound and southbound Rainier Avenue South to eastbound I-90 will be closed, and from 9:30pm Friday until 6:00am Saturday, the off-ramp from West Mercer Way to eastbound I-90 will be closed.
This closure will allow WSDOT tunnel maintenance crews to perform regular, scheduled maintenance in the Mount Baker and Mercer Island Lid tunnels. Work includes cleaning and testing fire detection cameras, testing fire hydrants and the emergency phone system, and sweeping shoulders and cleaning drains.
As always, you can see the latest road conditions on the WSDOT Real-Time Travel Map.
