The Ship Canal Trail: It’s like waiting for grass to grow

Ship Canal Water Quality Project update 09/05/2024

Restoration of the Ship Canal trail

The image above depicts the Ship Canal trail and the restoration in the surrounding area.

The Ship Canal Trail along the south side of the Ship Canal near Seattle Pacific University has reopened! If you’ve been by recently, you may have noticed fences still up along the trail. “But you aren’t working here anymore, so why can’t I go roll around in that lush grass?” you ask. Soon, my friend, soon.

Part of our responsibility on the project is restoration. Once we completed work in this area, we replanted vegetation and reseeded the soil. We are keeping the fencing up to give the grass an opportunity to grow. It needs to reach a length where it can be mowed at least once, and we want to ensure the grass has rooted properly. We expect to remove the fences in late fall, and then you can frolic to your heart’s content!

Ballard

Work at the Ballard site is minimal as the site awaits the next contractor. The site has been relatively quiet over the summer. Look for updates this fall as we prepare for construction on the new pump station and conveyance pipe 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 couple of weeks. Trail markings and signals will remain until the road and trail are fully restored anticipated for 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 early fall
  • 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.

Lane restrictions have started again in Leary Way NW for final paving. One lane in each direction will be maintained. The restrictions will be in place for several weeks until final paving is complete.

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 late 2024
  • 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 until late 2024
  • 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
  • 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 completing the 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 remove the bypass system and make final connections 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 as early as September 6, there will be lane closures along Interlake Ave N for utility installation. Later in September, there will be lane closures along N 35th St for utility work. Lane closures for utility work will occur during construction work hours, flaggers or temporary signals will route vehicles around the work area. Steel plates may be used to cover excavations during non-work hours. The utility installation work will take several weeks. Final pavement and sidewalk restoration will follow and will also take several weeks.

Stone Way N closure vehicle detour

  • Traffic is detoured via N 40th St and Wallingford Ave N, and via Woodland Park Ave N and N 34th St
  • The all-way stops remain in place at Woodland Park Ave N at both N 35th St and N 34th St, and at Wallingford Ave N and N 35th St
  • Stone Way N between N 34th St and N 35th St remains closed to vehicles and bicycles
  • Please adhere to Road Closed, Local Access Only, and Traffic Revision Ahead signage and follow marked detour routes

N 34th St detour

  • Vibrations typical of a construction site
  • Road and periodic sidewalk closures

Regular work hours will be Monday through Friday, 7 am to 6 pm. Night and weekend work may occur periodically.

Queen Anne

Crews have completed much of the site restoration. Crews are still working on minor installations and finalizing landscaping. The Ship Canal Trail is currently open in its original configuration. There may be localized trail detours in coming months as needed for crews to work. We will keep you updated on the timing of any remaining work.
