Please expect construction impacts between 6 pm and 6 am
As early as Monday, August 10, crews will work overnight to install a temporary sewer diversion pipe on 23rd Street Northeast at E Street Northeast, near the Auburn Municipal Airport. Crews will dig a trench in the road and bury the pipe. The temporary diversion pipe will keep sewer service running while we repair the M Street trunk sewer pipe.
Crews will also use 24th Street Northeast, near the Cascade Middle School, to store construction materials and equipment. Nearby residents may notice occasional truck traffic in this area.
The overnight work will take place between 6 pm and 6 am. We expect to finish these activities on the night of Friday, August 28.
One lane of traffic will remain open in each direction on E Street Northeast during construction. Nighttime work will help reduce traffic impacts. The schedule may be subject to change.
See the map on the back for more details. You can also view our interactive map on our website: kingcounty.gov/MStreetTrunkRehab.

The King County Wastewater Treatment Division is repairing about 2.6 miles of old concrete sewer pipe, with pipe sizes ranging from 18 to 36 inches wide, in Auburn. We are also repairing 45 maintenance holes and over 100 side sewer connections to homes and businesses. Rehabilitating the M Street Trunk will help preserve aging infrastructure and ensure the reliability of our regional wastewater system.
During the first phase of the project, we repaired 0.7 miles of pipe in 2025. In June 2026, crews began the second phase of the M Street Trunk Rehabilitation Project. Crews are repairing about 1.9 miles of sewer pipe serving the city of Auburn during this phase. Work is taking place between the intersection of 2nd Street Northeast and Pike Street Northeast and 23rd Street Northeast, near the Auburn Municipal Airport (Zones 30 and 36).
We will keep community members informed of project progress and be available to answer questions and address concerns throughout construction. Contact us at 206-263-9878 or email MStTrunkrepair@kingcounty.gov
We will provide additional translations or an interpreter at no cost.
