Seattle City Light crews plan to enhance the reliability of the electrical system by pulling new power lines across Interstate 5 at NE 60th Street in Seattle’s Ravenna neighborhood. 
Seattle City Light crews plan to enhance the reliability of the electrical system by pulling new power lines across Interstate 5 at NE 60th Street in Seattle’s Ravenna neighborhood.
To complete this work safely, crews must intermittently stop traffic on both directions of I-5 overnight for four nights starting on Monday, March 20. Traffic may be stopped for up to 25 minutes between Northgate Way and State Route 520 as crews pull power lines across the highway.
Drivers should expect delays and use alternate routes during construction.
Lane closure details:
Monday March 20 through the morning of Friday, March 24
- Crews will intermittently stop traffic on I-5 between Northgate Way and State Route 520 from 11:59 p.m. to 4 a.m.
- Additionally, on the first night only, the northbound I-5 off-ramp to Ravenna Blvd/NE 65th Street and the northbound I-5 on-ramp at NE 50th Street will be closed from 11:59 p.m. to 4 a.m.
- Washington State Patrol troopers will assist with traffic control and escort drivers through the construction zone. See the map on page 2 for more details.
Customers will benefit since the new power lines will allow switching between electrical circuits in neighborhoods on either side of I-5, thus reducing the number and duration of power outages.
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.
