Central Waterfront Transmission Line Relocation Project
Transmission Line Home
Updated: April 15, 2016
Phase 1 was completed in 2013. Phase 2 is expected to begin Q3 2016.
Large transmission lines that power Seattle are attached to the underside of the vulnerable Alaskan Way Viaduct. Seattle City Light has been working to relocate these transmission lines in advance of viaduct demolition. City Light has completed the first phase of the relocation. The second phase, which should take approximately 9 months, is expected to begin in mid-2016. Waiting lines for ferry traffic will be temporarily re-routed during the construction.
