Crews are conducting early utility investigations throughout the downtown waterfront to prepare for full construction of the Waterfront Seattle improvements. Currently, this early fieldwork includes transmission line relocation.

Impacts during this work include loud noise and vibrations, intermittent temporary lane restrictions on Alaskan Way and adjacent streets, and short pedestrian detours. We'll maintain business access and provide notice for all work that is expected to impact people who live, work, and commute through the area.

If you have questions or concerns about this work, please email us at or call the Waterfront Seattle Program line at 206.499.8040.

Crews are also finishing up Seawall construction – you can learn more about the project here. Please see the Seawall construction page for other work along the waterfront.


Work is underway as part of Phase 2 for the Central Transmission Line Relocation Project (TLR):

  • Temporary closure of pedestrian path at Columbia St. Pedestrians will be routed to the sidewalk along Colman Dock. Please follow the direction of signage to access your destination.
  • Work hours are from 7 AM – 5:30 PM, Monday – Friday.

Waterfront Seattle’s underground utility investigations underneath the Alaskan Way Viaduct and on Columbia St is now complete. Over the next week, crews will be in the area conducting follow-up land surveys at these sites. There are no traffic impacts, pedestrian detours or noise associated with this work. Thank you for your patience throughout this work.

What you can expect later this fall

We are closely coordinating with other projects in the area to minimize impacts to Alaskan Way and nearby routes.

  • Night work for Phase 2 of the Central Waterfront Transmission Line Relocation Project (TLR) is scheduled to begin in late November at S King St, to relocate an existing duct bank and install a drainage manhole.
