I-405 to have Full Closure First Weekend of April for Removal of Bridge

The state encourages motorists to plan ahead, given the construction work.

The Washington State Department of Transportation will close all lanes of Interstate 405 in Bellevue beginning at 11 pm on Friday, April 1 to 4 am Monday, April 4 for the removal of the Northeast 12th Street Bridge.

What's Happening?

Crews plan to close all freeway lanes in both directions between Northeast Eighth Street and State Route 520 the weekend of April 2-3 to remove the old Northeast 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.

Removing the bridge will allow crews to finish building a new, longer, wider bridge over Interstate 405 at Northeast 12th Street. The bridge is being replaced to make room for new northbound ramps from Northeast Eighth and Northeast 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 Northeast Eighth Street and SR 520 from Friday, April 1 at 11 pm to Monday, April 4 at 4 am. Crews also will close Northeast 12th Street from 112th Avenue Northeast to 116th Avenue Northeast and many area ramps during the same weekend.

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.
