City Light Reliability Work Will Affect Traffic on I-5

Seattle City Light is enhancing the reliability of its electrical system by transferring transmission lines onto new poles on the east and west sides of Interstate 5 at NE 60th Street. Intermittent rolling slowdowns in both directions on I-5 between Northgate Way and State Route 520 are necessary for motorist and worker safety.

Seattle City Light is enhancing the reliability of its electrical system by transferring transmission lines onto new poles on the east and west sides of Interstate 5 at NE 60th Street. Intermittent rolling slowdowns in both directions on I-5 between Northgate Way and State Route 520 are necessary for motorist and worker safety.

The two-day project is planned for early Tuesday morning, June 21, and early Wednesday morning, June 22, from 12:01 a.m. to 4 a.m. and is being coordinated with the Washington State Patrol. Traffic will be escorted through the construction zone. The map below shows the area affected by the rolling slowdowns. Multiple rolling slowdowns will be necessary with each lasting from 20 to 25 minutes. All on-ramp traffic from Northgate Way through SR 520 will be held and will merge with the next rolling slowdown. The I-5 express lanes will be closed.

Drivers are advised to carefully abide by traffic restrictions and consider using alternate routes during construction. Normal traffic flow will follow once the transfer of wire is complete.

Seattle City Light is the 10th largest public electric utility in the United States. It has some of the lowest cost customer rates of any urban utility, providing reliable, renewable and environmentally responsible power to about 750,000 Seattle area residents. City Light has been greenhouse gas neutral since 2005, the first electric utility in the nation to achieve that distinction
