City Light Continues Lynnwood Link Wire Relocations on I-5

Seattle City Light crews plan to relocate existing overhead power lines over Interstate 5 near Northeast 189th and 195th streets to support Sound Transit’s Lynnwood Link Extension project. This work will result in traffic impacts on October 22-25.

Crews will relocate existing overhead power lines over Interstate 5 in mid-to-late October.

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 Slowdown Limits on I-5

Rolling slowdowns will occur on the following dates:

  • Tuesday night (11:59 p.m.), October 22 to Wednesday morning (4 a.m.), October 23
  • Wednesday night (11:59 p.m.), October 23 to Thursday morning (4 a.m.), October 24
  • Thursday night (11:59 p.m.), October 24 to Friday morning (4 a.m.), October 25

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

  • On southbound I-5: I-405 Interchange, 196th Street Southwest, 44th Avenue West (Lynnwood), 220th Street Southwest, 236th Street Southwest (Mountlake Terrace), State Route 104 (Shoreline)
  • On northbound I-5: Northeast 175th Street, 5th Avenue Northeast (Shoreline), Northeast Northgate Way, Northeast 80th Street (Seattle)

Drivers should expect delays and consider using alternate routes during construction. Real-time traffic information is available on the WSDOT mobile app and the WSDOT Traffic Twitter feed.
