America's Byways Signs are MUTCD compliant (MUTCD D6-4) and use effective images for traffic and pedestrian safety concerns on highway routes. America's Byways Signs are helpful resources to aid in the protection of the health and safety on roads, and are not an alternative for required protective measures for eliminating or reducing hazards.
Compliance
Section 2D.55 National Scenic Byways Signs
Support
Certain roads have been designated by the U.S. Secretary of Transportation as National Scenic Byways or All-American Roads based on their archeological, cultural, historic, natural, recreational, or scenic qualities.
Option
State and local highway agencies may install the National Scenic Byways (D6-4 or D6-4a) signs at entrance points to a route that has been recognized by the U.S. Secretary of Transportation as a National Scenic Byway or an All-American Road. The D6-4 or D6-4a sign may be installed on route sign assemblies or as part of larger roadside structures. National Scenic Byways signs may also be installed at periodic intervals along the designated route and at intersections where the designated route turns or follows a different numbered highway. At locations where roadside features have been developed to enhance the traveler's experience such as rest areas, historic sites, interpretive facilities, or scenic overlooks, the National Scenic Byways sign may be placed on the associated sign assembly to inform travelers that the site contributes to the byway travel experience.
