M Street Trunk rehabilitation

The M Street Trunk Rehabilitation Project will repair about 2.6 miles of deteriorated sewer pipes in the City of Auburn.

Project description

The M Street Trunk Rehabilitation Project will repair approximately 2.6 miles of severely deteriorated 18, 24, 30, and 36-inch-diameter reinforced concrete pipe that has more than 100 side sewer connections to nearby properties. The project will also rehabilitate 45 precast maintenance holes.

Active construction is anticipated to occur during the summer window (May to October) of 2025 to 2026 when the wastewater flow is lower.

The design and construction of the project are divided into two phases with Phase 1 construction scheduled for Summer 2025 and Phase 2 for Summer 2026.

  • Phase 1 construction covers about 0.6 miles of the trunk covering zone 18, zone 24 and some sections of zone 30 starting from the intersection on 14th Street Northeast to south of 22nd Street Northeast.
  • Phase 2 design and construction covers about 2 miles of the trunk covering the remaining portion of Zone 30 and the full length of zone 36.
  • The map that follows displays the zones and year of construction.

Project area displaying 5 zones (work areas) and timeframe: Zone 36 (2026), Zone 30 (2026), Zone 30 (2025 and 2026), Zone 24 (2025) and Zone 18 (2025)

The M Street Trunk pipe serves a densely populated area with many schools, homes, and businesses in the City of Auburn. During construction for the project, there will be impacts to the travelling public including detours, temporary lane closures, and bus stop impacts. Additional impacts may include on-street parking restrictions, and noise and odors from the diversion pumps. This project may include overnight work. We will share more details as plans develop and will keep the community informed.

Project update

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).

November 6, 2026

Overnight work at the Auburn Municipal Airport, November 9-23

As early as Monday, November 9, crews will begin working overnight at the Auburn Municipal Airport near 22nd St. N.E. and E St. N.E. They will repair the sewer pipe, remove the temporary sewer bypass pipe, and restore the roadway. We expect to finish these activities by Monday, November 23. The schedule may be subject to change.

Work will take place at night between 6 pm and 6 am. This is to reduce impacts on the airport, traffic, and nearby businesses during the day.

Flaggers will guide vehicles and help traffic move in both directions near the work area.

What to expect during this work

  • Night work will occur within permitted hours between 6 pm and 6 am.
  • You will be able to use your sinks, toilets, and showers normally.
  • Crews will maintain driveway access.
  • Expect noise from trucks, generators, cranes, bucket trucks, and other construction equipment. Lights will be used to illuminate the work area.
  • There will be temporary lane and sidewalk closures. Please follow directions from flaggers and posted detour signs.
  • Restricted street parking along the temporary sewer diversion pipe and repair work areas.

Stay safe! Please watch for equipment in the area. Travel slowly. Follow signs and directions from flaggers in the work zone.
