Maintenance Plan

A six-year Centennial Trail Maintenance Plan was finalized in January, 2016, and identified six major maintenance projects that were completed the next year:

  • Repair Project 1:  Milepost .86 to 1.17 – Crack seal concrete panels.
  • Repair Project 2:  Milepost 3.6 to 5.6 – Repair corrugations and bulges.
  • Repair Project 3:  Milepost 6.8 to 9.8 – Repair tree root damage, eliminate debris/rock washouts onto trail, etc.
  • Repair Project 4:  Milepost 10.6 to 12.7 – Repair bulges, humps and tree root damage on the trail.  Joint fill on Denny Ashlock Bridge.  Eliminate rocks washing onto trail.
  • Repair Project 5:  Milepost 16.8 to 20.1 – Repair corrugations, waves and humps on separated trail portions.
  • Repair Project 6:  Milepost 29.1 to 31.9 – Repair large surface gaps in the trail from previous failed crack repair project.

The Centennial Trail is now ready for a new 1.5″ asphalt overlay, having received funding for Phases 1 & 2 from the State of Washington.  Work begins in spring, 2023!

Collaboration and cooperation made this much-needed maintenance project a reality. Our thanks to the Centennial Trail Coordinating Council for establishing the Centennial Trail Maintenance Fund.
