This Sunday, April 7, crews will continue investigative fieldwork for Phase 2 of the Central Waterfront Transmission Line Relocation Project. The work is necessary to complete the design that will lead to the relocation of transmission lines off the Alaskan Way Viaduct before it is demolished. Potholing activities outside of the Seattle Tunnel Partners work zone
This Sunday, April 7, 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.
- Crews anticipate continuing potholing activities outside of the fence at the intersections of Alaskan Way and five streets, including King, Jackson, Main, and Washington streets and Yesler Way. These activities will help locate the viaduct column foundation footings to inform the design alignment for the new duct bank.
- Crews plan to park a vactor truck along the STP fenced-off work zone (see map below) to complete this activity. There are no planned impacts to traffic or pedestrians, but the work will be outside the fence and visible.
- Potholing activities will occur in coordination with other area projects. Depending on the availability of crews and equipment, potholing could continue over the next several Sundays.
Work area.
Anticipated fieldwork activities over the next few weekends:
- Crews will be working from 9 a.m. to 6 p.m. on Sundays.
- No weekday fieldwork is anticipated.
- Potholing activities are anticipated to wrap up over the next several Sundays.
What is the Central Waterfront Transmission Line Relocation Project?
Transmission lines that power Seattle have historically been attached to the vulnerable Alaskan Way Viaduct. Seattle City Light has been working to complete full relocation of these transmission lines along Seattle’s waterfront in advance of viaduct demolition. 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 (see map). 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.
