Traffic Impacts for Final Phase of H-Frame System Upgrades

Drivers using I-5 and State Route 900 near Boeing Field should plan for delays and prepare to use alternate routes as Seattle City Light crews work to replace overhead utilities that span the busy highways on Fri., Oct. 24 to Sat., Oct. 25. To complete this work, City Light’s traffic control contractor will close both directions of I-5 between SR 599 and Boeing Access Road, and MLK Way (SR 900) between S 129th St and Boeing Access Road. The highway closures will provide crews with the space they need to safely replace an overhead communication and lightning protection cable.

City Light is working to increase the electrical capacity and reliability to the Duwamish Valley with the H-Frame Replacement and Feeder Installation Project. This is the final phase of construction to replace eight outdated H-Frame structures and cables that transmit electricity on high voltage lines across I-5 due to their age and increasing electricity demand. The project will improve system safety and increase electrical reliability for customers.

Seattle City Light Apologizes for I-5 Delays

Seattle City Light crews working on a project to upgrade towers for transmission and distribution lines that cross Interstate 5 were a few minutes late completing their work this morning.

That delay meant a late start for traffic control contractors in reopening I-5, which resulted in backups on the freeway.

We apologize to all commuters who were affected by the delay.

City Light Completes Phase 1 of H-Frame Project Ahead of Schedule

Seattle City Light crews completed the removal of high-voltage transmission wires one day early Monday morning as part of a project to replace H-Frame towers for power lines in the Duwamish neighborhood.

With the first phase of work done ahead of schedule, traffic restrictions planned on Interstate 5 tonight have been cancelled.

Seattle City Light will work with WSDOT to schedule two other phases of work that are necessary to complete the project.

City Light is replacing eight outdated H-Frame structures and cables that transmit electricity on high voltage lines across I-5 due to their age and increasing electricity demand. The project will improve system safety and increase electrical reliability for customers.

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.
