The project to improve water quality in the Ship Canal has expanded construction to four neighborhoods, including east Ballard near Fred Meyer.
The Ship Canal Water Quality Project, headed up by Seattle Public Utilities, is a multiyear undertaking to build a 2.7-mile long stormwater tunnel between Wallingford and Ballard. Crews have been working at the main Ballard site (24th and Shilshole) since last year, but have now expanded their work into all project areas; east Ballard, Fremont, Queen Anne, and Wallingford.
Earlier this week, SPU moved crews and equipment to the intersection of 11th Ave NW and NW 45th St, where they’ll be preparing the site for a 60-foot-deep, 10-foot-diameter vertical shaft to carry sewage to the new storage tunnel.
Initial work at the site will include minor street paving at the southwest corner of 11th Ave NW and NW 45th St. Crews will start building temporary bike lanes on the north side of NW 45th St for the upcoming Burke-Gilman Trail detour, which will begin sometime in the coming weeks.
SPU says over the next few weeks, residents and businesses should anticipate the following:
- Closures of NW 45th St between 9th and 11th Avenues NW during working hours to allow for construction of the trail detour. Traffic will be detoured onto NW 46th St. Please pay attention to flaggers on site.
- Intermittent closures of the southbound shoulder of 11th Ave NW south of NW 45th St. Two-way traffic will be maintained. Please pay attention to flaggers on site.
- Noise and vibrations typical of a construction site.
Meanwhile, work to construct the slurry wall at Shilshole and 24th continues. SPU says they expect to be working on the wall for the rest of the summer, and to expect the following in the area:
- Very heavy truck traffic on Shilshole Ave NW and 24th Ave NW; please pay attention to flaggers.
- Parking restrictions along the east side of 24th Ave NW so construction trucks can exit the work site.
- Noise and vibrations related to excavation and concrete pours.
