 How to Get Around During the Wallingford Conveyance Project Starting this Month
 This map shows the full Stone Way N closure that will be in place as early as January 30, 2023. This detour will be updated as construction progresses.
SPU needs to install new pipes along Stone Way N and N 35th St to connect Wallingford’s existing combined sewer outfall pipe to the future storage tunnel. Crews will begin moving into Stone Way N in mid-January 2023 and will continue working in the area through Fall 2024. To install these new pipes, there will be full and partial road closures and parking restrictions in the area. The first phase of work will close Stone Way N starting in early 2023 for at least one year.
Detours will shift over the course of the project. Businesses and buildings will remain open and accessible during construction. We will have more information to share in the coming weeks, including more details about detour timing, so please check out our project website and encourage members of your community to sign up for our project emails.
How to Get Around During the Full Closure of Stone Way N
 Please continue to communicate with us if you notice access issues while detours are in place. To learn more about the project and to see more detailed detour information, visit our project website. We also continue to update our Flickr albums with construction photos.
MudHoney
We’ve made it to Fremont! MudHoney, our 18-ft diameter tunnel boring machine, has tunneled over 9,000 feet! MudHoney will complete a planned maintenance stop in Fremont before continuing on toward Wallingford. 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 this year.
During regular tunneling activities, you should anticipate:
- Truck deliveries of concrete segments and MudHoney equipment
- Nighttime segment deliveries and both nighttime/daytime tunnel spoils being hauled off
- Noise and vibrations typical of a construction site
Crews are working 24 hours a day, six days a week.
Puget Sound Energy (PSE) has utility relocation work planned along NW 56th St in the upcoming months. Please contact 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:
- The contractor has returned to a one-lane traffic configuration on 11th Ave NW at NW 45th St. Traffic signals and flaggers will direct traffic at the intersection during single lane closures.
- 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 remains detoured to the north side of NW 45th St through the project area. 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.
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
We resumed tunneling our 8-ft diameter conveyance tunnel beneath the Ship Canal, and it is now over halfway to Queen Anne. Crews are backfilling around and working inside the diversion structure on 2nd Ave NW.
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 through mid-2023. 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, is closed through 2023
- Pedestrian detours are in place 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 and fans running during work hours to power pumps and equipment, and to provide fresh air to crews working in the shaft
- 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 6 pm; and some Saturdays from 9 am to 6 pm.
Wallingford
Crews are removing the remaining contaminated soil on the southwest corner of the site and preparing for construction of the electrical building.
You can also expect to see Wallingford Conveyance project crews moving onto Stone Way N between N 34th St and N 35th St in preparation for conveyance pipe installation and other utility work. We have reached out to nearby neighbors and businesses and will continue to share more details about this work.
Local closures and detours:
- As early as January 23, Puget Sound Energy will be removing parking spots on Stone Way N, between N 34th St and N 35th St, to complete necessary utility work
- As early as January 30, there will be a full closure of Stone Way N between N 34th St and N 35th St to vehicle traffic. A two-way bike lane and the sidewalk on the east side of Stone Way N will be maintained.
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 5:30 pm.
Unrelated to this project, please note that SPU crews will be doing emergency repair work on a storm drainage pipe on N 38th St near Stone Way N. Please contact Robert Lee at 206-775-4585 or robert.lee@seattle.gov if you have any questions.
Queen Anne
Crews installed the final 60-in conveyance pipe segment between the diversion structure and the shaft. The site is being prepared for installation of piping and an air duct inside the 8-ft diameter conveyance tunnel between Queen Anne and Fremont soon after tunneling is complete.
Local closures and detours:
- Localized Ship Canal Trail detour at least through summer 2023 (see map). 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.
