The National Scenic Byways Program is part of the U.S. Department of Transportation, Federal Highway Administration ( Established under the Intermodal Surface Transportation Efficiency Act of 1991, the program is an effort established to help recognize, preserve and enhance selected roads throughout the United States. The program was reauthorized and expanded significantly in 1998 under TEA-21 and again under SAFETEA-LU in 2005.

The U.S. Secretary of Transportation recognizes certain roads as National Scenic Byways based on one or more archeological, cultural, historic, natural, recreational, and scenic qualities.

Criteria for the designation of National Scenic Byways were published in the Federal Register on May 18, 1995 ( byways/fedreg.pdf).
