Project background
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.

Additional parking and construction Information
