They each have adopted a two-mile stretch of highway and have agreed to clean it two or three times a year.
The employees of Pilkington Auto Glass in Flagstaff cleaned the section of local highway they have adopted during a highway pickup session on Saturday, June 4.
The Adopt-a-Highway program has been in Arizona since 1988.
Volunteers have saved the state a considerable amount of money each year by picking up trash.
A sign marks the section of highway with the name of the group that cleans the area. ADOT supplies vests and trash bags.
Any organization is able to adopt a section of highway. Most of the sections of highway in and near towns are taken, but sections in more remote areas are often available for adoption.
The sections are renewable every two years. If someone wants to adopt a stretch of highway, they go through safety training, which includes a video. The average number of volunteers in a group is six to 10 and no one under 12 is allowed to participate.
