 Night work at South King Street to relocate an existing duct bank and install a drainage manhole is scheduled to begin in November.

 What to expect at Columbia Street:

  • Temporarily closure of pedestrian path at Columbia Street. Please follow the direction of signage to access your destination.
  • Work hours are from 7 a.m. to 5:30 p.m., Monday through Thursday.

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 relocate 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.
