The Washington State Department of Transportation said the closure will begin with WB I-90 reducing to one laneAll westbound lanes of I-90 will be closed west of Island Crest Way from 10 a.m. Friday, Sept. 23 to 5 a.m. Monday, Sept. 26. Drivers will need to take I-405 to go around the lake or take State Route 520 to cross the lake.
This weekend, there is a University of Washington Football home game Saturday night and a Seahawks home game Sunday afternoon. Project Engineer Shawn Wendt said the closures during large events are not ideal and can't be avoided. "We have been trying to schedule this work for several months, but supply chain issues have pushed us back into September, and we need to finish the project this fall while there is still good weather to allow the concrete to cure," Wendt said. "This expansion joint is old and needs to be replaced. If it were to break, that would require an emergency repair that could affect peak traffic periods.
