City Light to relocate power lines over I-5 at NE 155th during night hours

Seattle City Light crews plan to relocate several overhead power lines on Interstate 5 at NE 155th St in Shoreline. 

The work, which supports Sound Transit’s Lynnwood Link Extension project, will result in overnight traffic impacts on February 10-12 from 1 - 3am.

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 – 3am
• Feb. 11 (Thursday morning): 1 – 3am
• Feb. 12 (Friday morning): 1 – 3am

Traffic using the following on-ramps to I-5 will be affected:

• On southbound I-5: 220th St SW (Mountlake Terrace), State Route 104, N 175th St and the King County Metro North Base (Shoreline)
• On northbound I-5: 5th Ave NE (Shoreline), NE Northgate Way, NE 80th St and NE 70th St (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.
