City Light will be dragging electrical cables across I-5 Tuesday overnight

Feeder cable work for Sound Transit Lynnwood Link Extension will cause rolling slowdowns overnight from 11:59pm Tuesday, July 30 to to 4am Wednesday, July 31.

Seattle City Light crews plan to maintain the reliability of the electrical system by relocating existing overhead power lines on Interstate 5 near NE 155th St in Shoreline. 

This work will support Sound Transit’s Lynnwood Link Extension project.

To complete this work safely, crews must intermittently conduct rolling slowdowns of traffic in both directions of I-5 to ensure safe work operations and passage for motorists.

The work will start late Tuesday night on July 30. 

Traffic will be intercepted and escorted at slow speeds for up to 15 minutes between 44th Avenue West (Lynnwood) and NE 70th St (Seattle) as crews pull overhead feeder cables across the highway. 

Traffic will return to normal speeds once past the work area.

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

On southbound I-5: 

• 44th Ave W (Lynnwood), 
• 220th St SW (Mountlake Terrace), 
• State Route 104 / NE 205th (Shoreline)
• 175th St NE (Shoreline)

On northbound I-5: 

• 5th Ave NE (Shoreline), 
• NE Northgate Way (Seattle), 
• NE 80th St(Seattle)
• NE 70th Street (Seattle)

Drivers should expect delays and consider using alternate routes during construction.
