 Summer safety: Navigating construction zones
 Workers in high-visibility gear work in the roadway to repave North 45th Street in Ballard.
If you’ve spent a few seasons in Washington, then you know that summer is a construction-heavy time of year. At the bottom of every email update, we call attention to the fact that construction safety is everyone’s job. Public safety around construction sites in the summer is especially vital because more people are outside and coming in contact with active work zones. As you enjoy the summer weather, it’s important to stay aware of construction sites. The sites have large machines, uneven ground, loud noises that can impair hearing and other potential hazards. Look out for warning and directional signage, workers in high-visibility gear, and changes to your normal routes.
Here are some safety tips to keep in mind:
- Stick to signed pedestrian, vehicle, and bike detours
- Bikes and cars need to slow down
- Use safety flags at crosswalks where available
- Be mindful of driving during certain times of day when the sun might obstruct your vision
- Stay clear of our construction zones, no matter how much fun it looks like our crews are having!
By paying attention and being careful, you can enjoy your summer adventures in the city without any mishaps. So stay alert to protect your safety and that of our construction crews to make sure summer fun doesn’t get interrupted by any construciton site dangers.

Ballard
Work at the Ballard site is beginning to slow down as crews finish preparing the site for the next contractor. The site will be relatively quiet over the summer. Look for updates later this summer and fall as we prepare for construction on the new pump station and conveyance pipes to begin.
East Ballard
Crews continue sidewalk restoration and paving in 11th Ave NW and NW 45th St between 11th Ave NW and 9th Ave NW. 11th Ave NW will be fully open after paving is complete. Beginning the week of July 8, 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) will temporarily move to the newly paved area within the NW 45th St roadway for several weeks. Then the trail will be moved back to its original location along the south side on NW 45th St. This interim move is to allow for adjacent site restoration work. Trail markings and signals will still be in place and flaggers will be on site during construction working hours (Monday through Friday, approximately 7am to 4pm).
We expect the BGT to be relocated back to its original location by mid-August.
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 and temporarily relocated beginning the week of July 8
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.
Leary Way NW is expected to fully reopen by late-July. Later this summer, there will be lane closures 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
- 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 fall 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
Beginning the week of July 8, the sidewalk on the west side of Stone Way N between N 34th St and N 35th St is closed for replacement. This work will take several weeks.
Starting as early as July 29, 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, will be closed for several weeks. The crosswalk on the north side of N 34th St across Stone Way N will also be closed. Crews will be doing utility work, then paving and restoring the roadway. See our updated detour map. There will be 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 will need to exit eastbound to Wallingford Ave N and follow the signed detour route. 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. 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 remove the temporary concrete wall around the top perimeter of the shaft, install equipment inside the shaft and build the above-ground electrical building. Crews removed a portion of the temporary screen wall on the east side of the site to make way for buried utilities and a permanent retaining wall and will remove the remainder of the temporary screen wall over the next few months.
Starting as early as mid-August, there will be single 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 and flaggers 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.
