Overnight lane and ramp closures on eastbound Interstate 90 between East Mercer Way and I-405 are scheduled through Monday morning, 16 November. WSDOT’s current project notice gives work hours of 9 pm to 5 am, with signed detours for closed ramps.
United StatesThe US$6.7 million Mercer Slough Bridge rehabilitation covers nearly one mile of eastbound I-90 from Bellevue Way Southeast to I-405. Crews are installing new bearing seats, modifying expansion joints and fitting new expansion seals. The wider project runs through 2027, with two full overnight eastbound closures tentatively expected in spring 2027.
Why it matters
The current lane restrictions provide access for work within a busy highway corridor. The distinction between this overnight programme and the tentative full closures matters for transport planning. Drivers and delivery teams should check WSDOT’s current notices as the sequence develops.
