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 August 12-14 and August 19-20.

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.

Rolling slowdowns will occur on the following dates:

  • Monday night (11:59 p.m.), August 12 to Tuesday morning (4 a.m.), August 13
  • Tuesday night (11:59 p.m.), August 13 to Wednesday morning (4 a.m.), August 14
  • Monday night (11:59 p.m.), August 19 to Tuesday morning (4 a.m.), August 20
