Central Waterfront Transmission Line Relocation Project
Transmission lines that power Seattle have historically been attached to the Alaskan Way Viaduct. Since 2008, Seattle City Light has been working to complete the full relocation of these transmission lines along Seattle’s waterfront. The Central Waterfront Transmission Line Relocation Project (TLR) must be completed before Alaskan Way Viaduct removal, Waterfront Seattle and new Alaskan Way construction.
We relocated transmission lines near the sports stadiums and Pioneer Square before the southernmost mile of the viaduct was demolished in 2010. In 2012, Seattle City Light completed the relocation of a section of these transmission lines along the central waterfront, moving them to a permanent location underground between Yesler Way and the Union Street substation. Seattle City Light is in the process of permanently relocating the final section, Phase 2, from Yesler Way to South King Street. The project is expected to be complete in end of year 2017.
The first step toward a new waterfront
The Central Waterfront Transmission Line Relocation Project must be completed before Alaskan Way Viaduct removal. Thus, work is a vital preliminary step in the transformation of the Central Waterfront.
