  Current temporary art installations on display at four Ship Canal Water Quality Project sites.
The latest temporary artworks from FLOW are now on display in Fremont, Ballard, Wallingford and East Ballard. Enjoy the start of Fall with a stroll through your neighborhood to look for these pieces and learn about their stories. You can learn more about the artists and their art on our website.
We also encourage you to look at our latest construction photos on Flickr to see the progress that has been made.
Ballard & MudHoney
MudHoney, the 18-ft storage tunnel boring machine (TBM), has tunneled over 150 feet and placed about 25 concrete rings (check out our TBM fact sheet to learn about these tunnel rings).
During tunneling, you should anticipate:
- Heavy equipment, such as cranes, being installed on site
- Truck deliveries of MudHoney equipment
- Tunneling activities
- Nighttime truck traffic including concrete segment deliveries and removal of tunnel spoils (dirt taken out of the tunnel)
- Noise and vibrations typical of a construction site
Crews are working 24 hours a day, 5 days a week, and will continue until the tunnel reaches Wallingford in fall 2022. Weekend work may also occur.
Ground monitoring is ongoing along the tunnel alignment and done from both inside MudHoney and on the surface.
East Ballard
Through the end of the year, crews are installing a temporary water main, dewatering wells, and excavation and construction of the large, below grade mechanical and electrical vault in NW 45th St. Both lanes of 11th Ave NW, south of NW 45th St, have reopened.
During this time, you should anticipate:
- The final connections for the water main bypass will require a short, temporary water outage. If your service will be impacted, you'll receive a door hanger with more information.
- Heavy equipment in the area
- NW 45th St closed to traffic; vehicles must detour onto NW 46th St
- Burke-Gilman Trail users remain detoured to the north side of NW 45th St. Flaggers will help direct traffic during daytime working hours. Please follow all detour guidance on site. 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.
- 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
Work on the 8-ft conveyance tunnel continues. Crews also continue working intermittently in Leary Way NW on a new water main. This work will require some lane closures on Leary Way NW and a short, temporary water outage.
Please note that Canal Street will temporarily be closed for Oktoberfest this weekend, Sept. 17- Sept. 19. We’ve worked with the organizers to reduce the impacts of our project during this event. Please visit the event website for more information.
During this time, you should anticipate:
- An increase in truck traffic on Leary Way NW as dump trucks haul away spoils from tunneling
- Excavators working on site for utility installation work
- Truck traffic on Leary Way NW as trucks bring materials to the site
- NW 36th St between Leary Way NW and 3rd Ave NW closed (through remainder of the project)
- Pedestrians detoured to the north side of Leary Way NW
- Generator running during work hours to power the TBM and associated equipment
- 2nd Ave NW, between Leary Way NW and NW Canal St, closed to vehicle and pedestrian traffic for sewer and diversion structure work through the end of the year
- NW Canal St is open to two-way traffic to allow access during this closure. Please do not park at the west end of NW Canal St to allow two-way traffic to turn around at the closure.
- 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.
Wallingford
Crews have begun working on the shaft liner wall.
During this work, you should anticipate:
- Trucks coming in and out of the site to deliver reinforcing steel and concrete
- Noise and vibrations typical of a construction site
Regular work hours will be Monday through Friday, from 7 am to 5 pm.
Queen Anne
Crews will begin installing temporary shoring for construction of the diversion structures.
During this time, you should anticipate:
- Trucks coming in and out of the site
- Noise and vibrations typical of a construction site
