The National Scenic Byways Program is part of the U.S. Department of Transportation, Federal Highway Administration. Established in Title 23, Section 162 of the United States Code under the Intermodal Surface Transportation Efficiency Act of 1991 and reauthorized and expanded significantly in 1998 under TEA-21 and again under SAFETEA-LU in 2005, the program is a grass-roots collaborative effort established to help recognize, preserve and enhance selected roads throughout the United States.
FHWA's May 18, 1995 interim policy (PDF, Text) provides the criteria for the National Scenic Byways Program. This policy sets forth the procedures for the designation by the U.S. Secretary of Transportation of certain roads as National Scenic Byways or All-American Roads based on their archaeological, cultural, historic, natural, recreational, and scenic qualities. There are 150 such designated byways in 46 states. FHWA promotes the collection as America 's Byways®. This policy also specifies the type of projects eligible for funding and lists the funding priority for grants.
America's Byways® - Designed for the traveler, offers maps, photos, stories, activities, and visitor information to help plan a trip on any one of the 150 distinct and diverse roads designated by the U.S. Secretary of Transportation. Additionally, the traveler can research information on US Forest Service Byways, Bureau of Land Management (BLM) Back Country Byways, and US Fish and Wildlife Refuges located along or near America's Byways, as well as state-designated scenic byways.
