WSDOTis preparing for the first full weekend closure of both directions of I-405 through Bothell as part of the I-405 expansion project.
Starting6 p.m. Saturday, March 7, to 4 a.m. Monday, March 9,crews will close all lanes of northbound I-405 at the SR 522 Interchange and all lanes of southbound I-405 from SR 527 to SR 522 to remove ramp sections over I-405.Similar closures are planned for the following weekend, as well.
WSDOT has to fully close I-405 to safely remove portions of aging flyover ramps over the mainline freeway.
What you need to do:Expect severe regional delays. Although these closures are happening in Bothell, detour routes won’t be able to handle normal I-405 traffic volumes. This means significant congestion is highly likely in Kirkland – including along 100th Ave NE, Juanita-Woodinville Road, and 124th Ave NE to the north, and NE 116th St, 98th Ave NE / Market St, NE 85th St, and 124th Ave NE in central/south Kirkland.All drivers should follow official signed detours and avoid cutting through neighborhood streets. Signed routes are coordinated to help keep traffic moving.
Pro tip*if possible* – use transit, adjust travel times by leaving early or staying later, or avoid travel in the area during the weekend. Plan ahead and allow for plenty of extra time.
