The Idaho Adopt A Highway program originated in 1990 as part of Idaho’s Centennial Celebration. Volunteer groups commit to pick up litter along a two-mile stretch of highway twice yearly and deposit it in bags provided by ITD. The Idaho Transportation Department maintenance crews gather the bagged litter for disposal.

Volunteer groups are recognized for their service to the community with signage posted at the beginning of their chosen road segment. There is no cost to participate in the program. ITD supplies the group with loaned safety vests, trash bags and highway signage advising traffic there is a litter pick up activity currently underway on the roadside. Over the years, the Adopt-a-Highway program has accounted for millions of dollars in savings that were then redirected to highway construction and needed maintenance to improve highways and bridges.
ITD estimates the Adopt A Highway Program saves approximately $750,000 annually. There are more than 1,000 active volunteer groups participating in the statewide program. More than half of Idaho’s highways have been adopted but there are still many highway segments available for adoption.
