WSDOT to close I-405 for weekend, Main Street for 5 months

Posted on Jun 09, 2022

As part of the I-405/ Renton to Bellevue Widening and Express Toll Lanes project, the state Department of Transportation will close Main Street, between 112th and 116th avenues, starting as early as Monday, June 13. The closure will be in place approximately five months and the primary detour route will be on Northeast Fourth Street.

In addition, WSDOT will close I-405 in both directions from 10 p.m. Friday, June 17, to 5 a.m. Monday, June 20, so crews can safely demolish the Main Street Bridge over Interstate 405. The new overpass, including a multipurpose path for people who walk and bicycle, will allow WSDOT to widen the freeway as part of the Renton to Bellevue project.

More information and maps of the detour routes are available are available through the city’s Traffic Advisories.
