Potholing activities will occur in coordination with other area projects
On Thursday, June 27, crews will continue investigative fieldwork for Phase 2 of the Central Waterfront Transmission Line Relocation Project. This includes potholing activities outside of the Seattle Tunnel Partners (STP) fenced-off work zone, in Alaskan Way.
  • On Thursday, crews anticipate potholing activities at the intersections of Alaskan Way and South Main, Jackson, and King streets.
  • Crews will temporarily and intermittently impact traffic and pedestrians. Crews will park a vactor truck in the intersection to pothole and identify existing utilities. Flaggers will be on-site to direct traffic and pedestrians/bicycles through the area
  • Crews will be working from 9 a.m. to 4 p.m.
Project background
Transmission lines that power Seattle have historically been attached to the vulnerable Alaskan Way Viaduct. Seattle City Light has been working to relocate these transmission lines along Seattle's waterfront in advance of viaduct demolition. Seattle City Light is ready to complete the design for permanent relocation of the final section of central waterfront transmission lines. This section of 115 kV transmission lines runs from King Street to Yesler Way. Seattle City Light is working to identify a route for the transmission lines in an underground duct bank in a path just west of the existing viaduct.
