 Connect with your Ship Canal through the Saltwater Soundwalk
 Our friends over at the Seattle Office of Arts & Culture, in collaboration with artists Jenny Asarnow and Rachel Lam (Anigiduwagi enrolled Cherokee Nation), have been thoughtfully curating a podcast, Saltwater Soundwalk, which explores our responsibilities and relationship with the Salish Sea and connecting waters. The podcast centers Indigenous Coast Salish voices and language.
Saltwater Soundwalk is a podcast that takes listeners on a journey from Gas Works Park along the Burke Gilman trail to the entrance of the Ship Canal at the Fremont Bridge, and explores the people, land and waterways that define Seattle. The artists created Saltwater Soundwalk as a site-specific audio experience that explores our relationships and responsibilities towards the Salish Sea and connecting waters, centering Indigenous Coast Salish voices and language.
Learn more about the Saltwater Soundwalk via this blog post or on the Ship Canal Water Quality art page, and listen to the full collection wherever you get your podcasts. If you’re in the area, the podcast can turn into a walking tour through the Ballard, Fremont, and Wallingford neighborhoods!
As always, you can also check out Flickr for the latest project construction photos.
MudHoney
MudHoney, our 18-ft diameter tunnel boring machine, is paused for maintenance after reaching East Ballard this month. Once tunneling resumes in several weeks, follow along with our tunneling tracker on our project website.
Ground monitoring is ongoing along the tunnel alignment and is done from both inside MudHoney and on the surface.

Ballard
Our Ballard shaft site near Shilshole Ave NW continues to be busy with tunneling activities, including delivering new cutter tools to MudHoney and carrying out maintenance on the support equipment before tunneling resumes.
During regular tunneling activities, you should anticipate:
- Truck deliveries of concrete segments and MudHoney equipment
- Nighttime segment deliveries and tunnel spoils being hauled off
- Noise and vibrations typical of a construction site
Crews are working 24 hours a day, six days a week and will continue until MudHoney reaches Wallingford in 2023. Sunday work may also occur. The Ballard shaft site is also the site of the future pump station.
East Ballard
Crews continue building the mechanical and electrical vault in NW 45th St and the diversion structure on 11th Ave NW, requiring the road to be reduced to a single lane.
Local closures and detours:
- One-lane closure on 11th Ave NW through November 2022. Traffic signals direct northbound and southbound traffic on 11th Ave NW and eastbound traffic on NW 45th St as well as bicyclists and pedestrian trail users. During working hours, flaggers will assist with construction vehicles entering and exiting the site. Directional signage is also in place. For safety, bicyclists should either dismount or cross train tracks at a 90-degree angle. Please use extra caution in wet weather as ramps may be slippery.
- NW 45th St remains closed to traffic between 11th Ave NW and 9th Ave NW; vehicles must detour onto NW 46th St
- Burke-Gilman Trail detour to the north side of NW 45th St through the project area
You should anticipate:
- Heavy equipment in the area
- Noise and vibrations typical of a construction site
Regular work hours will be Monday through Friday, from 7 am to 5 pm. Night and weekend work may occur.
Fremont
Crews have started working on the diversion structure on 2nd Ave NW. Preparations also continue for conveyance tunneling within the Fremont site’s east end, near 2nd Ave NW.
Local closures and detours:
- 2nd Ave NW, between Leary Way NW and NW Canal St, closed to vehicle and pedestrian traffic through the end of 2022. NW Canal St is open to two-way traffic to allow access during this closure.
- NW 36th St, between Leary Way NW and 3rd Ave NW, closed through the remainder of the project
- Pedestrian detours on Leary Way NW; please follow all detour guidance on site
You should anticipate:
- Truck traffic on Leary Way NW as trucks bring materials and equipment to and from the site
- Generators running during work hours to power pumps and equipment
- Noise and vibrations typical of a construction site
Regular work hours will be Monday through Friday, from 7 am to 5 pm. Crews also continue to work on large eight-foot conveyance tunnel pipes underneath white tents within the site from 7 am to 10 pm on weekdays, and possibly 9 am to 10 pm on weekends, over the next few weeks.
Wallingford
Crews have poured the upper portion of the Wallingford shaft walls and are now focused on forming the walls of the odor control facility, which will be housed on the east side of the shaft. Crews will be working inside the underground garage of the Brooks Building through September. They will be using an air compressor to complete the work, which will be screened to muffle the sound.
You should anticipate:
- Concrete trucks coming in and out of the site
- Noise and vibrations typical of a construction site
Regular work hours will be Monday through Friday, from 7 am to 5:30 pm.
Queen Anne
Crews continue constructing underground vaults through the summer.
Local closures and detours:
- Localized Ship Canal Trail detour at least through summer 2023 (see map). The South Ship Canal Trail has been temporarily adjusted for construction of the third below-grade vault through summer 2022 and will revert back to the detour shown in the linked map this fall. Our contractor will be working on both sides of the trail so please continue to remain alert when moving through this area.
- West Ewing Mini Park parking closure through mid-2023
You should anticipate:
- Trucks coming in and out of the site
- Noise and vibrations typical of a construction site
Regular work hours will be Monday through Friday, from 7 am to 5 pm. Night and weekend work may occur.
