Crews are beginning early utility investigations and geotechnical work throughout the downtown waterfront to prepare for full construction of the Waterfront Seattle improvements. This early fieldwork will include transmission line relocation, geotechnical drilling, and underground utility investigations through potholing.

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.


What you can expect between Yesler Way and S King Street

Phase 2 of Seattle City Light's Central Waterfront Transmission Line Relocation Project is underway. The majority of work will take place behind the SR 99 Tunnel Project fenced-off work zone on Alaskan Way. Visit the project website for more information.

  • Daytime work hours are from 7 AM – 5:30 PM, Monday – Thursday. S King St west of Alaskan Way is scheduled to be open by the end of this week. Although vehicles are restricted, flaggers will direct pedestrian and bicycle traffic to access the Elliott Bay Trail at S King St.
  • Work may occasionally occur on Saturdays during daytime hours, 7 AM to 3:30 PM, from June through August.

What you can expect this summer

Due to the number of projects ongoing in and around the waterfront area this summer, our utility investigations prioritized the most critical locations through the end of June. We are closely coordinating with other projects in the area to minimize impacts to Alaskan Way and nearby routes.

  • Phase 2 of Seattle City Light's Central Waterfront Transmission Line Relocation Project will continue, including occasional work on Saturdays during daytime hours, from June through August.
  • Crews may conduct a few days of utility investigations work near Pine Street in the Seawall construction zone, as well as on the roadway and near parking between Bell and Lenora streets, this summer. We will continue additional work in September, as needed.
