The Adopt-a-Highway program, also known as Sponsor-a-Highway is a promotional campaign undertaken by U.S. states, Provinces and Territories of Canada and 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, for example) is allowed to have their name posted on a sign in the section of the highways they maintain.
