 Saying goodbye to MudHoney and welcoming new pipes to Wallingford!
 Part of MudHoney’s front shield was hauled off via a ‘normal’ oversized truck last week. Larger trucks have hauled away larger pieces during a couple of nighttime shifts. There will be a few more nighttime hauls in the coming weeks.
MudHoney continues to be dismantled and brought off-site to be reused or recycled. That work is expected to wrap up in August, including hauling several large pieces off-site with oversized trucks over the coming weeks. Keep an eye on I-5, you may see one of the last segments cruising down the highway!
In other news, the Wallingford Conveyance project will be expanding its work zone soon. See map for key elements of the project.
Beginning as early as the week of Aug. 14, N 35th St will be closed between Stone Way N and Interlake Ave N. Since work on this project began earlier this year, a gas main was relocated, a temporary sewer bypass pipe was installed, and crews constructed the diversion structure on Stone Way. With MudHoney soon to be fully out of the neighborhood, crews will be expanding into N 35th St to install conveyance pipes that will extend from the diversion structure and connect to the new storage tunnel.
We are developing detour maps to help you navigate. If you are a driver, the detour will be similar to the routes and signage that were in place earlier this year. These detours will remain in place until early 2024. We are working directly with adjacent neighbors to ensure access to businesses and properties will be maintained.
We will continue to provide updates through our website and email.
To learn more about the project, visit our project website. We also continue to update our Flickr albums with recent construction photos.
Farewell MudHoney
Our 18-ft diameter storage tunnel boring machine wrapped up its journey to Wallingford earlier this summer. Crew members have been busy dismantling it and hauling off pieces to be reused and recycled. That work is expected to be completed in August.

Wallingford Conveyance crews continue to install pipes and access maintenance holes in the north portion of the intersection at N 34th St and Stone Way N. The left turn lane from N Northlake Way onto westbound N 34th St is also closed and will be opened again toward the end of August. The traffic detour is similar to the routes and signage that were in place earlier this year. Please dismount and walk your bike on the open sidewalk on the east and west sides of Stone Way N or use detour routes.
