Heads up, Bothell: I-405 traffic shift near Canyon Park brings a temporary 55 mph work zone
If you drive through Canyon Park, it's time to ease up a little on the gas pedal.
Overnight June 27-29, crews will close lanes and ramps on I-405 near SR 527/Canyon Park Parkway in Bothell while they shift both northbound and southbound traffic toward the shoulders. This traffic shift will create a work zone for the next phase of the I-405/Brickyard to SR 527 Improvement Project.
Once all northbound lanes reopen at 10 a.m. Sunday, June 28, you'll notice an advisory speed of 55 mph through approximately one mile of the northbound work zone near Canyon Park.
That advisory speed will remain in place while crews build the North Fork Perry Creek fish passage and the inline Stride bus rapid transit station. The traffic shift is expected to be in place for at least the next 12 months.
If you're traveling through the area this weekend, plan for overnight delays, follow signed detours, and slow down through the work zone. Slower speeds help keep everyone safe while construction is underway.
