Transmission Line Home

Updated: August 7, 2018

Transmission lines that power Seattle have historically been attached to the Alaskan Way Viaduct. Starting in 2008, Seattle City Light began work to complete the full relocation of these transmission lines along Seattle’s waterfront. The Central Waterfront Transmission Line Relocation Project (TLR) was a vital preliminary step before Alaskan Way Viaduct removal, Waterfront Seattle and new Alaskan Way construction could begin. The project was completed in early June 2018.
