2019 Trail Resurfacing Projects

Each year, Three Rivers Park District identifies locations to perform preventative maintenance projects throughout the regional trail system to extend the life of the trails, parking lots and roadways. The type of projects and anticipated impacts include the following:

  • Microsurfacing: This work involves the installation of a thin surface layer to seal the existing pavement. The work requires the trail to be closed for a few days so the material can dry. Drying time can vary, so a trail will typically remain closed until the entire segment is dry. A trail repair project typically occurs one month prior to a microsurfacing project to correct surface deficiencies.
  • Trail Repair: This work includes the repairing/filling of cracks and patching or replacing the concrete and bituminous surfaces with deficiencies. The pavements will remain open during this work but users should use caution when approaching active construction.
  • Chip Seal: This work involves coating the surface with an emulsion product followed by installation of small aggregate. Once the aggregate is embedded into the emulsion, the excess material can be removed and the pavement can be reopened to users.
  • Striping: Surface restriping occurs after microsurfacing, chip seal and in areas where larger pavement sections have been repaired. Parking lots will be temporarily closed during installation. Trails and roads will remain open to users.

See a map of the 2019 projects. Please note that Medicine Lake Regional Trail will be closed July 30 and 31 for reapplication of microsurfacing material due to weather. See park and trail pages for more detailed information on construction updates.
