Overnight bridge paving to close northbound I-405 in Kirkland April 29; additional nightly lane reductions planned through May 5

All northbound traffic will use Northeast 85th Street collector-distributor

KIRKLAND – Four nights of bridge deck repairs kick off on Saturday, April 29, with a closure of northbound Interstate 405 in Kirkland. During the overnight closure, all traffic will shift to the Northeast 85th Street collector/distributor. Work on southbound I-405 in both Kirkland and Bothell is scheduled to begin Sunday, April 30, with the interstate reduced overnight to a single lane.

This weather-dependent work will repair the driving surfaces on three bridges damaged by winter weather in 2021-22. It represents the final major portion of the Northwest Region Emergency Pavement Repair project.

People traveling along I-405 in Kirkland and Bothell should expect slowdowns and congestion during the work.

Following heavy snowfall during December 2021, Gov. Jay Inslee signed an emergency proclamation Jan. 8, 2022, to fund 88 pavement repair projects across King, Snohomish, Skagit and Whatcom counties, including the three bridges in Kirkland and Bothell. The $7 million project is scheduled to wrap up this year with permanent striping still to be completed at several locations.

Slow down – lives are on the line. 

In 2023, speeding continued to be a top reason for work zone crashes.

Even one life lost is too many.

Fatal work zone crashes doubled in 2023 - Washington had 10 fatal work zone crashes on state roads.

It's in EVERYONE’S best interest.

95% of people hurt in work zones are drivers, their passengers or passing pedestrians, not just our road crews.
