The Caltrans Adopt-A-Highway Program provides for individuals, organizations, or businesses to help maintain sections of roadside within California's State Highway System. Groups have the option to participate as volunteers or to hire a maintenance service provider to perform the work on their behalf.

Since 1989 the Adopt-A-Highway program has been one of the truly successful government-public partnerships of our time. More than 120,000 Californians have cleaned and enhanced over 15,000 shoulder-miles of roadside.

Participation can include one or more of the following activities:

  • Removing litter (work frequency varies with location)
  • Planting and establishing trees or wildflowers
  • Removing Graffiti
  • Controlling vegetation

Adoptions usually span a two-mile stretch of roadside and permits are issued for five-year periods. Groups in good standing may renew their permits indefinitely.
