Outdoor Advertising Magazine - Since the enactment of the Federal Highway Beautification Act of 1965, the number of outdoor advertising signs in the United States has, and will continue to decrease due to highway projects. Public projects led by local municipalities and redevelopment districts have also resulted in a decrease in the number of outdoor advertising signs.
Highway or redevelopment projects do not usually provide for the relocation of outdoor advertising signs, and many local zoning ordinances prohibit the rebuilding or relocation of outdoor advertising signs that must be removed in order to accommodate projects.
