 A complicated network: Utility project coordination
Ship Canal Water Quality Project update 08/22/2024
Crews at the East Ballard site install a complex array of electrical conduits inside the base slab of the mechanical and electrical vault.
Have you heard of a mycorrhizal (my-koh-RYE-zul) network? It’s a network of fungi that connects plants and trees underground, allowing them to transfer water, nutrients, and minerals. These connections can stretch for hundreds or even thousands of miles, creating a huge web of tiny threads that intertwines with the roots of plants and trees. Pretty cool!
We, as humans, have developed a similar underground network that links our homes and cities with essential resources like water, waste removal, and more. This system is vast and intricate, with a single tunnel often housing sewer lines, stormwater systems, and fiber optic cables. It's a complex and vital part of our modern infrastructure.

Working on a small section of a road often means coordinating with different agencies and companies. We might be working near a gas line, temporarily turning off water service, avoiding fiber-optic cables, and managing traffic—all of which need teamwork with different groups. Plus, the work itself might require several specialized contractors to complete.
Our project is part of a large network. SPU's work sends wastewater to a treatment plant, but this network also supports other essential services provided by different agencies and organizations.
Just like plants and trees connected by fungi, we all work together as individuals to help the whole community.

Ballard
Work at the Ballard site is minimal as the site awaits the next contractor. The site will be relatively quiet over the summer. Look for updates this fall as we prepare for construction on the new pump station and conveyance pipes to begin later this year.
East Ballard
Crews continue sidewalk restoration and paving in 11th Ave NW and in NW 45th St between 11th Ave NW and 9th Ave NW. 11th Ave NW will be fully open in a few weeks after paving is complete. The Burke Gilman Trail (BGT), between 9th Ave NW and 11th Ave NW (between the US Post Office building and the Ballard Fred Meyer store) has been temporarily moved to the newly paved area within the southern portion of NW 45th St roadway. This interim move is to allow for restoration work on the north side of NW 45th St and in 11th Ave NW. The trail will be moved back to its original location west of 11th Ave NW in a few weeks. Trail markings and signals will remain until the road and trail are fully restored anticipated for early this fall.
Lane closures and detours:
- 11th Ave NW is reduced to one lane of traffic, with temporary signals in place during restoration work
- NW 45th St between 11th Ave NW and 9th Ave NW remains closed until later this summer
- The Burke Gilman trail detour remains in place
You should anticipate:
- Heavy equipment in the area
- Noise and vibrations typical of a construction site
- Paving equipment in the area
Regular work hours will be Monday through Friday, from 7 am to 4 pm.
Fremont
Crews continue installing equipment inside the shaft and buried utilities at the site. They also continue installing mechanical and electrical systems inside the vault in N 36th St.
Starting the end of August there will be lane closures in Leary Way NW for final paving.
Local closures and detours:
- On 2nd Ave NW, between Leary Way NW and NW Canal St, the street remains closed to vehicle and pedestrian traffic until fall 2024

- Trucks entering and leaving the site
- Fans running during work hours to provide fresh air to crews working in the shaft
- 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 6 pm; and some Saturdays from 9 am to 6 pm.
Wallingford
The north half of N 34th St at Stone Way N, including the left turn lane from N Northlake Way onto westbound N 34th St, continues to be closed for several more weeks. Crews will be doing utility work, then paving and restoring the roadway.
See our updated detour map.
- Pedestrian crosswalk on the north side of N 34th St across Stone Way N is closed
- Local access only on westbound N 34th St from Wallingford Ave N, including access to the North Transfer Station
- Vehicles leaving the North Transfer Station must exit eastbound to Wallingford Ave N and follow the signed detour route
- Local access only on Woodlawn Ave N between N 34th St and N 35th St
Last year, this area was closed so we could install a bypass for the sewer system that would allow us to install the new pipes. Over 600 feet of deep, large diameter pipe has been installed on N 35th St and Stone Way N. This year, we need to cut off the bypass system and make final connection of the new pipes and complete final pavement restoration. Thank you for your patience and understanding.
The pedestrian crosswalk on the south side of the intersection of Stone Way N and N 35th St remains closed. The other three crosswalks continue to be open.
Within the site at the northeast corner of N 35th St and Interlake Ave N, crews continue to install equipment inside the shaft, build the above-ground electrical building, and remove the temporary screen wall on the east and north sides of the site.
Starting in September, there will be lane closures near the intersection along both N 35th St and Interlake Ave N for utility installation. Lane closures will occur during construction work hours, flaggers or temporary signals will route vehicles around the work area. The utility installation work will take several weeks. Final pavement and sidewalk restoration will follow and will also take several weeks.
