More construction fencing means more room for art in Wallingford!

As the road closure in Wallingford moves from N 34th St to N 35th St the week of August 21 (see below for more information), new art from our local artists is ready for you to enjoy on Stone Way N. Take a walk through our Wallingford construction area, safely following all pedestrian detours and signage of course, and bask in the brilliance of our new temporary artwork by Angie Hinojos, Addison Karl, and Toka Valu. Learn more about these artists and all the art showcased along the Ship Canal Water Quality Project on our website’s art page.

Updated Wallingford detour maps

New detour maps will help you navigate the changes coming to Wallingford at the intersection of Stone Way N and N 35th St. If you want to ride your bicycle, be sure to check out the Bicycle and Pedestrian Detour map for alternative bike-friendly routes. Please remember to dismount and walk your bike on sidewalks for safety. Drivers, we have you covered too. The vehicle detour after August 21 will be like the routes and signage that were in place earlier this year except N 34th St will be available instead of N 35th St. These detours are expected to remain in place until early 2024. We are working directly with adjacent neighbors to maintain access to all businesses.

Upcoming lane reductions in Fremont on Leary Way NW

Starting August 14, there will be lane reductions on Leary Way NW, between NW 39th St and 1st Ave NW so crews can install a vent shaft that will connect to the new tunnel. The lane reductions are expected to be in place for four to six weeks. One lane of Leary Way NW will be kept open in each direction (see the Fremont section below for details).

We will continue to provide updates by email and on our website. Check out our Flickr albums for the latest construction photos.

Farewell MudHoney (the long goodbye is almost over)

Our 18-ft diameter storage tunnel boring machine wrapped up its journey to Wallingford earlier this summer. Crew members have been busy dismantling it and hauling off pieces to be reused and recycled. There are so many pieces that need to be taken apart and removed separately, we want to thank our neighbors for their patience especially during those early morning oversized load runs. But it will be ending soon, the hauling off work is expected to be completed this month.


Ballard

Crews continue to dismantle, clean, and remove the equipment that was needed to build the tunnel.

You should anticipate:

  • Trucks entering and leaving the site to support the removal of equipment and materials no longer needed to support MudHoney
  • Nighttime truck movements may be necessary to remove the particularly large equipment over the next few months
  • Noise and vibrations typical of a construction site

Crews are working 20 hours a day, six days a week. Some work may occur on Sundays.


East Ballard

Crews continue to work inside the adit and shaft on NW 45th St, and in the diversion structure on 11th Ave NW. Crews also continue to install the conveyance pipe that will extend from the diversion structure to the storage tunnel.

Local closures and detours:

  • There continues to be 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 (BGT) 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 take extra caution in wet weather as ramps may be slippery. There is a slightly narrowed trail for a short stretch that will be restored as soon as work in that area is complete.

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 6 pm. Night and weekend work may occur.


Fremont

Crews continue to build the permanent structure inside the shaft, which will contain the pipes that connect the conveyance tunnel to the storage tunnel. They also continue to work on the large underground mechanical and electrical vault.  

Starting August 14, crews will begin work on the vent shaft which connects to the top of our new 18-ft diameter tunnel underneath Leary Way NW between NW 39th St and 1st Ave NW. This work should take approximately four to six weeks.

Local closures and detours:

  • Starting August 14, our contractor will close the two southernmost lanes of Leary Way NW and shift traffic to the northernmost lanes to maintain one lane of traffic in each direction. This configuration should remain in place 24 hours a day for approximately 4 weeks.
  • After the two-lane closure, our contractor will perform utility work in Leary Way NW and will close the two southernmost eastbound lanes of Leary Way NW between 9 am and 3 pm, Monday through Friday. In October, there will be a night shift to connect the new watermain to the existing system. We will share more when we have details on this work.
  • On 2nd Ave NW, between Leary Way NW and NW Canal St, the street remains closed to vehicle and pedestrian traffic through 2023
  • NW Canal St is open to two-way traffic during this closure
  • NW 36th St, between Leary Way NW and 3rd Ave NW, remains closed through 2023
  • Pedestrian detours are in place on Leary Way NW; please follow all detour guidance

You should anticipate:

  • Truck traffic on Leary Way NW as trucks bring materials and equipment to and from the site
  • Concrete 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

Crews continue to dismantle and remove MudHoney from the Wallingford site. This work is expected to be completed by the end of August.

Wallingford Conveyance crews continue to install pipes and access maintenance holes in the north portion of the intersection at N 34th St and Stone Way N.

At this time, the left turn lane from Northlake Way onto westbound N 34th St is closed. However, it will be re-opened soon, prior to any closure of N 35th St. Please walk your bike on the open sidewalk on the west side of Stone Way N or use alternative routes.

Starting as early as Monday, August 21, N 35th St will be closed from Stone Way N through Interlake Ave N. N 34th St will reopen to two-way traffic prior to the closure of N 35th St.
