The Adopt-a-Highway program, and the very similar Sponsor-a-Highway, are promotional campaigns undertaken by U.S. states, provinces and territories of Canada, and some national governments outside North America to encourage volunteers to keep a section of a highway free from litter. In exchange for regular litter removal, an organization (such as Cub Scouts or Knights of Columbus) is allowed to have its name posted on a sign in the section of the highways they maintain.
