A National Scenic Byway is a road recognized by the United States Department of Transportation for its archeological, cultural, historic, natural, recreational, and/or scenic qualities. The program was established by Congress in 1991 to preserve and protect the nation's scenic but often less-traveled roads and promote tourism and economic development. The program is administered by the Federal Highway Administration.
The most scenic of the roads in the program are designated All-American Roads. The designation means they have features that do not exist elsewhere in the United States and are scenic enough to be tourist destinations unto themselves. As of September 2005, there are 99 National Scenic Byways and 27 All-American Roads, located in 44 states (all except Hawaii, Massachusetts, Nebraska, New Jersey, Rhode Island, and Texas)
