Full Closure of I-405 in Downtown Bellevue April 1-4

NE 12th St. Bridge Removal Requires Full Closure of I-405

Alternate Routes Required

Crews plan to close all freeway lanes in both directions between NE Eighth Street and SR 520 the weekend of April 2-3 to remove the old NE 12th Street Bridge. Crews must close the freeway because they can’t safely take down the bridge while traffic passes under it. With nearly 450,000 vehicles traveling this route on a typical weekend, the closure is Washington State Department of Transportation’s biggest this construction season.

Why is WDSOT removing the bridge? Removing the bridge will allow crews to finish building a new, longer, wider bridge over I-405 at NE 12th Street. We're replacing the bridge to make room for new northbound ramps from NE Eighth and NE 10th streets. The project will improve safety and traffic flow between I-405 and SR 520.

Where and when will I-405 close? Crews will close I-405 in both directions between NE Eighth Street and SR 520 from Friday, April 1 at 11 p.m. to Monday, April 4 at 4 a.m. Crews also will close NE 12th Street from 112th Ave. NE to 116th Ave. NE and many area ramps during the same weekend.

How do I prepare? Please plan ahead, use alternate routes or defer trips during the 53-hour closure period. Plan for congestion throughout the region and allow extra time for travel. For any questions or more information, contact Steve Peer at steve.peer@i405.wsdot.wa.gov or 425-456-8624.

Be aware of other closures that may impact your trip. The City of Tukwila Southcenter Access Project will start closures in the Renton and Tukwila area on March 28th. What are the detours? During the I-405 closure, drivers should avoid the area or take alternate routes. Use the recommended regional routes unless you plan to visit Bellevue. Downtown Bellevue will be open for business. Drivers should expect heavy traffic on the detour routes and throughout the region.
