Starting as early as 7 pm on Wednesday, July 15, crews working for King County will close the driveway to D Street Northeast to the Auburn Municipal Airport at the intersection of 23rd Street Northeast and E Street Northeast until 5 am on July 16. Crews will use this closure to pull the lid off and conduct rehabilitation work in the maintenance hole. This work is part of the M Street Sewer Trunk Rehabilitation project.
To safely complete construction activities, only local access will be allowed north of 22nd Street Northeast and south of 26th Street Northeast. Others traveling in the area will be detoured onto Auburn Way North. Flaggers will guide vehicles on both ends of the work area to guide local access and help traffic move in both directions.

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.
