It's a bird! It's a plane! It's a ...crane!

If you’re passing by our Ballard site, take a look up and check out the 250-ton crane towering over the work zone! The crane arrived from the mid-west in early April and crews have been busy assembling this massive piece of equipment.

The crane’s first assignment is to assist with slurry wall construction, one of the earliest phases for vertical shaft construction. It will be an 87-ft diameter, 210-ft deep, 4-ft thick reinforced concrete circular structure which will keep walls from collapsing during shaft excavation. You may experience additional noise and vibrations associated with this work.

Eventually, when the shaft is complete, we'll launch our tunnel boring machine through it!

Ballard’s 24th Ave NW Pier is open to the public!

We are pleased to share that the 24th Ave NW Pier has been temporarily re-opened to the public!

It will close again in late August to support construction activities, so we hope you get a chance to enjoy it while the sun is out this summer. Next year, crews will use the pier to carry tunnel spoils away by barge, which will reduce the number of truck trips needed and help mitigate traffic impacts.

February 2020

Construction in Ballard will begin as early as February 20

Starting the week of February 20, crews wil begin installing a 12’ high sound wall, stormwater controls, and dewatering equipment at the Ballard site. For more information, please see a copy of the construction flyer that went out to more than 2,100 businesses and residents near the work site.

November Public art update

Over the summer, our Wallingford artist, RYAN! Feddersen, asked community members what water means to them. Their responses inspired her to create temporary artwork along the Ship Canal alignment that is activated by rain. Next time you’re walking along the tunnel alignment, take a look at the sidewalk and learn about why your neighbors value water. The installations are expected to last between four and six months.

October 2019

Early work at our Ballard site is underway!

Crews are preparing our Ballard site for tunneling. Here are the activities they’re working on:

  • Replacing the 24th Ave NW Pier to prepare for removing tunnel spoils by barge
  • Replacing the outfall pipe under the pier
  • Relocating utilities
  • Removing contaminated soils from the shaft site

Public art

Local artist Vaughn Bell is leading several artists to install permanent artwork along the storage tunnel alignment across all five neighborhoods. Artists will use a wide variety of mediums, materials and techniques to make our underground infrastructure and regional water quality improvements more visible.

Some goals of the Ship Canal public art include:

  • Increasing public awareness of the function of water quality projects and infrastructure
  • Making an invisible system more visible
  • Connecting people to the flow of water in their city, their home and local ecology
  • Creating meaningful, inspiring and thought-provoking art experiences in the public realm

Artwork will include both permanent and temporary installations.
