This Saturday, April 20 and Sunday, April 21, crews will continue investigative fieldwork for Phase 2 of the Central Waterfront Transmission Line Relocation Project. Utility location (potholing) activities will occur inside and outside of the Seattle Tunnel Partners (STP) fenced-off work zone. Depending on the availability of crews and equipment, potholing could continue over the next several weekends.
- Crews anticipate continuing potholing activities inside the STP fence on Saturday.
- On Sunday, crews anticipate continuing potholing activities outside of the fence at the intersection of Alaskan Way and King Street. These activities will help locate the viaduct column foundation footings and existing utilities 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.
Work Area
Anticipated fieldwork activities over the next few weekends:
- Crews will be working from 9 a.m. to 6 p.m. both days this weekend.
- Potholing activities are anticipated to wrap up over the next several weekends.
- No weekday fieldwork is anticipated for this project, although crews will be in the area working on other projects during the week. Waterfront Seattle crews will be conducting potholing activities on Railroad Way S for Waterfront Seattle. To learn more about this work, check out Waterfront Seattle’s flyer.
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.
Design alignment reaches 60% milestone
Phase 2 of the Central Waterfront Transmission Line Relocation Project has reached 60% design. The design will continue to be refined over the coming months as the project team moves toward 90% this fall.
