Project Update 8/9/2017:
Civil work, including excavation, installation of conduits, encasement in concrete backfill and restoration of the surface for TLR Phase 2 is complete. Cable pulling and splicing of the transmission lines must be accomplished while the lines are de-energized. No power outages are anticipated during the work. Pulling cables through the new duct banks is expected to begin in September from the existing vaults at Columbia Street to the existing vaults under the viaduct near South King Street, and is anticipated to last approximately two months. Night work is also expected at the intersection of South King Street and Alaskan Way starting in early September.
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.
