 Welcome to Fremont, MudHoney!
 MudHoney negotiates a tight corner before arriving at our Fremont construction site.
MudHoney has had quite a run so far in 2023. On January 5, 2023, MudHoney, our 18-foot diameter tunnel boring machine, hit a personal tunneling record: 95 feet in one day! That means MudHoney placed 18 tunnel rings in one 24-hour shift. Way to go, MudHoney!
Things slowed down once MudHoney began navigating a tight turn just before arriving in Fremont. Like how you shout at your 16-year-old nephew to slow down when driving around sharp turns on the road, our engineers tell MudHoney to slow down as it negotiates a corner in our tunneling route. On Thursday, Jan. 12, MudHoney placed its 1,881st tunnel ring before stopping at the Fremont construction site. MudHoney stayed here for a couple of weeks for a planned maintenance stop before continuing on its journey to Wallingford this week.
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.
Please continue to communicate with us if you notice access issues while detours are in place around our project sites.
MudHoney
We’ve made it to Fremont! Our 18-ft diameter tunnel boring machine has tunneled over 9,100 feet! MudHoney completed a planned maintenance stop in Fremont and just restarted its journey 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, including the reinforced concrete floor and walls.
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
Crews continue working on our 8-ft diameter conveyance tunnel beneath the Ship Canal, which is now just about to enter the shaft at 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 removed the remaining contaminated soil on the southwest corner of the site and are 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:
- Puget Sound Energy mobilized this week and will be removing parking spots and reducing lanes on Stone Way N, between N 34th St and N 35th St, to complete necessary utility work
- As early as Feb. 6, 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 prepare to install piping and an air duct inside the 8-ft diameter conveyance tunnel between Queen Anne and Fremont soon after tunneling is complete. Tunneling is anticipated to be done in the next few weeks.
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.
