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City Light is replacing eight outdated H-Frame structures and cables that transmit electricity on high voltage lines across I-5 due to their age and increasing electricity demand.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.
