During 2025, volunteers with the Arizona Department of Transportation’s (ADOT) Adopt a Highway program made significant contributions to maintaining state highways. According to ADOT, these volunteers collected 12,211 bags of litter. A total of 7,270 individuals participated across 764 groups, working a combined 16,163 hours. The estimated value of their efforts is $545,000.
Mary Currie, ADOT’s Adopt a Highway Program Manager, said: “ADOT is grateful to these civic-minded individuals and groups who dedicate time and effort to their adopted stretches of highway. We hope their contributions inspire others to follow their example by volunteering themselves, encouraging others not to litter and securing their loads.”
The program allows groups to adopt segments of state highways for cleanup duties. Each group receives a two-year permit and is responsible for picking up litter at least once per year—preferably three or more times annually—on assigned sections that are generally about a mile in each direction and located mostly in rural areas considered safe for volunteers. ADOT provides safety vests, litter bags, and training for the cleanup events.
Groups participating in the program are recognized with signs displaying their names on the adopted highway stretches.
