See you in 2022!

We’ll see you in the new year with more feature stories and neighborhood updates. As always, we encourage you to check out our Flickr albums with recent construction photos, including images of our new tunnel.


Ballard & MudHoney

MudHoney continues to be on a planned pause for trailing gear installation and will resume tunneling activities early next year.

When tunneling starts again, you should anticipate:

  • Truck deliveries of concrete segments and MudHoney equipment
  • Tunneling activities
  • Nighttime segment deliveries and tunnel spoils getting hauled off
  • Noise and vibrations typical of a construction site

Crews are working 24 hours a day, 5 days a week, and will continue until MudHoney reaches Wallingford in late 2022. Weekend work may also occur.

Crews will not be working on Friday, December 24 and Friday, December 31.

Ground monitoring is ongoing along the tunnel alignment and is done from both inside MudHoney and on the surface.

  • Burke-Gilman Trail users remain detoured to the north side of NW 45th St
  • Flaggers will help direct traffic during daytime working hours. Please follow all detour guidance on site. For safety, bicyclists should either dismount or cross train tracks at a 90-degree angle. Please use extra caution in wet weather as ramps may be slippery.

Regular work hours will be from 7 am to 5 pm Monday through Friday. Night and weekend work may occur. Crews will not be working on Friday, December 24 and Friday, December 31.
