Seattle City Light continues to relocate existing overhead power lines on Interstate 5 to support Sound Transit’s Lynnwood Link Extension project. This work will result in traffic impacts on September 16-18.

To complete this work safely, Washington State Patrol troopers and contracted 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 Lynnwood and north Seattle as crews pull overhead feeder cables across the highway. Traffic will return to normal speeds once past the work area.C

Rolling slowdowns will occur on the following dates:

  • Monday night (11:59 p.m.), September 16 to Tuesday morning (4 a.m.), September 17
  • Tuesday night (11:59 p.m.), September 17 to Wednesday morning (4 a.m.), September 18

  • On southbound I-5: 44th Avenue West (Lynnwood), 220th Street Southwest (Mountlake Terrace), State Route 104 and Northeast 175th Street (Shoreline)
  • On northbound I-5:  5th Avenue Northeast (Shoreline), Northeast Northgate Way, Northeast 80th Street and Northeast 70th Street (Seattle)
