City Light System Reliability work to affect traffic on I-5 from Oct 7-9

Power line relocation work for Sound Transit Lynnwood Link Extension will cause rolling slowdowns on I-5

Seattle City Light crews plan to relocate existing overhead power lines over Interstate 5 near NE 200th and 203rd streets to support Sound Transit’s Lynnwood Link Extension project. This work will result in traffic impacts on October 7-9.

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.), October 7 to Tuesday morning (4am), October 8
• Tuesday night (11:59 p.m.), October 8 to Wednesday morning (4am), October 9

Additional Details:

• Traffic using the following on-ramps to I-5 will be affected:
• On southbound I-5: 196th St SW, 44th Ave W (Lynnwood), 220th St SW (Mountlake Terrace), State Route 104 (Shoreline)
• On northbound I-5: NE 175th St, 5th Ave NE (Shoreline), NE Northgate Way, NE 80th St (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.
