Tunnel boring machine for Ship Canal Water Quality Project on its way to Ballard

The Ship Canal Water Quality Project is still underway and a massive German tunnel boring machine has arrived at the Port of Tacoma.

Over the next few months, each piece shipped separately from Germany will find its way to Ballard, where the entire machine will be assembled.

Other updates on the project are happening in Ballard too, as the final concrete walls on the vertical shaft are being installed over the next few weeks.

As the tunnel boring machine arrives for assembly and the vertical shaft get finished, the Ballard community can expect delivery trucks in and out of the site through Shilshole Ave NW and 24th Ave NW from NW Market St. There will also be on and off concrete pour days, where trucks will be coming in and out frequently with concrete.

Residents can expect construction hours to stay approximately between 7 am to 5 pm Monday through Friday. However, for the next few weeks, these hours will go up to 7 am – 2:30 am Monday through Friday and most Saturdays as tunnel preparation beings.

In East Ballard, ground improvement work and soil stabilization is happening in NW 45th St and 11th Ave NW south of NW 45th St. Due to this, NW 45th St is closed to traffic, and vehicles should expect to detour onto NW 46th St. Burke-Gilman Trail users will continue to be detoured to the north side of NW 45th St and 11th Ave NW, south of NW 45th St will remain reduced to one-lane traffic. This reduction is expected to last through most of the year. Two-way traffic on 11th Ave NW will also continue in the southbound lane.
