Central Waterfront Transmission Line Relocation

Posting Date: 1/22/2013                

Contact: Tamara Jenkins - Project Manager

Phone: 206-684-7714

 Updated: January 2018

Beginning the first week of January, crews plan to work at the intersection of South King Street and Alaskan Way to relocate an existing duct bank and install a drainage manhole. This work also requires some initial utility investigations. Crews will primarily work at night to minimize traffic and access restrictions, with some daytime work to minimize noise impacts. 

Expect lane closures during nighttime work hours on Alaskan Way, South King Street, and Railroad Way to divert traffic around the work site. Flaggers will be on-site to direct vehicle and bike traffic, and signed detours will be posted on surrounding blocks. No pedestrian impacts are expected. This work is anticipated to be complete by April 2018. Please see our website for more details on work hours and impacts. 

Nearly all of this work will occur in the intersection of Alaskan Way and King St. Staging of materials and equipment will be done inside STP’s fenced area.

What is the Central Waterfront Transmission Line Relocation Project?

Transmission lines that power Seattle have historically been attached to the vulnerable Alaskan Way Viaduct. Seattle City Light has been working to relocate transmission lines along Seattle's waterfront in advance of viaduct demolition. City Light is ready to complete the design for permanent relocation of the final section of central waterfront transmission lines.
