Weekend-long northbound I-5 lane reductions in Lynnwood, April 7-10

First of many preservation projects to also close Alderwood Mall Boulevard

SHORELINE – The first of many highway preservation projects in King, Snohomish, Skagit and Whatcom counties will kick off in Lynnwood this weekend, April 7-10. Two lanes of northbound Interstate 5 at 44th Avenue and both directions of Alderwood Mall Boulevard will close for concrete bridge deck work.

The two bridges are the first of 17 included in a project to fix damaged pavement to preserve their integrity, extend their lifespan and provide a smoother ride for users.

Lynnwood closure information

From 10 p.m. Friday, April 7, through 5 a.m. Monday, April 10, contractor crews will close:

  • The two right lanes of northbound I-5 on the bridge over 44th Avenue. The HOV lane will be open to all vehicles in the area during the closure.
  • The on-ramp from 220th Street Southwest in Mountlake Terrace to northbound I-5.
  • All lanes of Alderwood Mall Boulevard between 33rd Avenue West and 40th Avenue West.
    - The Interurban Trail along Alderwood Mall Boulevard will remain open to pedestrians and bicyclists.

Bridge repair in Snohomish and Skagit counties

The following week, April 11-14, crews will move east within Snohomish County for work on the South Fork Skykomish River Bridge on US 2 in Gold Bar. Flaggers and a pilot car will assist travelers as eastbound and westbound traffic alternates through a single lane while crews work.

The weekend of April 14-16, crews will fully close the bridge on State Route 9 over the Skagit River between the South Skagit Highway and Diamond Road in Sedro-Woolley. Travelers will be detoured around the closure using SR 20, SR 538 and I-5.

This work is weather-dependent and may be rescheduled.
