Construction alert

Night closures of the northbound I-5 right lanes and guideway

Starting as early as Monday, March 20, Sound Transit will close the northbound I-5 right lanes and Sound Transit Guideway from NE 145th Street to NE 161st Street, including the King County Metro off-ramp. This work is for barrier removal, guardrail installation, and landscaping work for the future Lynnwood Link Extension light rail project.

What to know:

  • Northbound I-5 right lane, and King County Metro off-ramp will be closed (See map).
  • Crews will work at night to minimize traffic effects.
  • Residents can expect construction noise from equipment being operated at night, such as a cad truck, spreader truck, and light plant.
  • Most work will involve typical noise to adjacent neighbors, not much louder than freeway noise.
  • This night work should take four days to complete. If the work becomes delayed, a new flyer will be provided to residents.


  • Northbound I-5 right lane
    • Monday, March 20, from 10 p.m. to 5 a.m. the following morning.
