Project Description

What's Happening Now?

Project Update (Feb. 11, 2021): Crews completed their work on Feb. 10 and 11. As a result, the Feb. 12 rolling slowdowns are canceled. 

Additional rolling slowdowns may be scheduled in the future. We will update this page when those dates are announced.

Anticipated Impacts

  • To complete this work safely, Washington State Patrol troopers and construction crews must intermittently conduct rolling slowdowns of traffic in both directions of I-5 to ensure safe work operations and passage for motorists. Traffic will be intercepted and escorted at slow speeds for up to 15 minutes between Mountlake Terrace and north Seattle as crews pull overhead feeder cables across the freeway. Traffic will return to normal speeds once vehicles pass the work area. 
  • Rolling slowdowns will occur on the following dates: 
    • Feb. 10 (Wednesday morning): 1-3 a.m.
    • Feb. 11 (Thursday morning): 1-3 a.m.
    • Feb. 12 (Friday morning): 1-3 a.m.
  • Traffic using the following on-ramps to I-5 will be affected:  
    • On southbound I-5: 220th Street Southwest (Mountlake Terrace), State Route 104, North 175th Street and the King County Metro North Base (Shoreline) 
    • On northbound I-5: 5th Avenue Northeast (Shoreline), Northeast Northgate Way, Northeast 80th Street and Northeast 70th Street (Seattle) 
  • Drivers should expect delays and plan to use alternate routes during construction. Real-time traffic information is available on the WSDOT mobile app and the WSDOT Traffic Twitter feed.  
  • Please be aware that this electrical reliability work requires crew members to work closely together for their safety. This work follows protocols in place to meet all COVID-19 guidelines from the Centers for Disease Control and Prevention, Washington State Department of Health, and Occupational Safety and Health Administration.  For more information on Sound Transit's Lynnwood Link Extension project, please visit  soundtransit.org/system-expansion/lynnwood-link-extension.
