Adopt-A-County Road

Modeled after a national program, the Adopt-A-County Road program began in 1990 as a way to keep roadways litter-free. The program has grown to:

  • approximately 1000 volunteers
  • 80 groups
  • 138 miles of roadway cleaned.

Volunteers find the program to be a positive experience that allows their group to interact with each other and their community.

To learn more about joining the program, please visit the “How to start” tab, or send us an email.

Thank you to Western Disposal Services for their continued support with the Adopt-A-Road Program.
