 Have you spotted the recent additions to the neighborhood?
 Temporary art installations are displayed at four Ship Canal Water Quality Project sites
We recently installed four new temporary art pieces in Ballard, East Ballard, Fremont, and Wallingford. Enjoy the start of fall with a stroll through the Ship Canal project corridor to look for these pieces and learn about their stories. You can learn more about the artists and their art on our website.
FLOW: Art Along the Ship Canal is a program that uses our construction fences as a backdrop to allow artists to showcase their unique voice and perspective. Many of our public art pieces focus on sustainability and the love of water. This edition of FLOW art features vibrant tapestries, kaleidoscopes, a visual love letter, and the celebration of immigrants.
To learn more about the project, visit our project website. We also continue to update our Flickr albums with recent construction photos.
MudHoney
MudHoney, our 18-ft diameter tunnel boring machine, has currently tunneled over 6,000 feet! 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 will continue to be busy with tunneling activities until MudHoney reaches Wallingford in 2023.
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. Sunday work may also occur. The Ballard shaft site is also the site of the future pump station.
Puget Sound Energy (PSE) has started utility relocation work between 28th Ave NW and NW 56th St. After work on this intersection is complete, they will begin work between 26th Ave NW and NW 56th St.
Neighbors should have received notification directly from PSE. Please contact their project manager, Eric Liaw at eric.liaw@pse.com if you have any questions.
East Ballard
Crews continue building the mechanical and electrical vault on NW 45th St and the diversion structure on 11th Ave NW.
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

- Generators and fans running during work hours to power pumps and equipment, and to provide fresh air to crews
- Crane on-site to lower pipe segments for tunneling
- 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 completed constructing the walls of the underground odor control facility, which will be housed on the east side of the shaft. Later this month crews will begin removing the remaining contaminated soils in the southwest corner of the site.
