The Washington State Department of Transportation (WSDOT) announced that all eastbound lanes of Interstate 90 and its associated on‑ramps will be closed overnight on November 6 for essential tunnel maintenance. The shutdown begins at 8:30 p.m., with full lane closure by 10 p.m., and traffic is expected to resume by 6 a.m. on November 7.
What drivers can expect
According to WSDOT, the closures affect the stretch of eastbound I‑90 from Rainier Avenue South (milepost 3) to 77th Avenue Southeast (milepost 6) on Mercer Island. In addition, the eastbound on‑ramps from both northbound and southbound I‑5, as well as the on‑ramps from northbound and southbound Rainier Avenue South, will be shuttered for the duration of the work.
Motorists traveling between Seattle and Mercer Island should plan alternate routes, such as using the westbound I‑90 lanes, the I‑5 corridor, or local streets, to avoid the closed sections. Real‑time traffic updates are available on the WSDOT website at wsdot.com/travel/real-time/.
Purpose of the work
WSDOT crews will focus on fire‑system testing, minor light repairs, road sweeping, and drain cleaning within the tunnel. These routine tasks are part of the agency’s ongoing effort to keep Washington’s transportation infrastructure safe and reliable for commuters, businesses, and emergency responders.
“WSDOT keeps people, businesses and the economy moving by operating and improving the state’s transportation systems,” the agency’s website states, underscoring the importance of regular maintenance to prevent larger disruptions later.
Impact on the community
Mercer Island residents and commuters from the Eastside and Seattle area rely heavily on I‑90 for daily travel, making the temporary closure a notable inconvenience. However, the scheduled timing—overnight hours—minimizes disruption to peak‑hour traffic and aligns with the department’s commitment to maintaining critical infrastructure while respecting the flow of commerce and family life.
Local businesses near the affected on‑ramps have been advised to inform customers of the temporary access changes. Parents planning evening activities or late‑night pickups should allow extra travel time or consider alternative routes.
Tips for a smoother commute
- Check real‑time traffic conditions before departing.
- Use navigation apps that offer live rerouting.
- Allow additional travel time if you must travel during the closure window.
- Consider carpooling or public transit options where feasible.
By completing these maintenance tasks now, WSDOT aims to ensure that I‑90 remains a safe, efficient corridor for the region’s families, businesses, and commuters in the months and years ahead.
