According the their website, the National Scenic Byways Program (part of the U.S. Department of Transportation, Federal Highway Administration) is "a grass-roots collaborative effort established to help recognize, preserve and enhance selected roads throughout the United States". My goal, of course - drive them all!
I've paid special attention to the Lincoln Highway and Historic National Road and do not show them here. Also see my tracking spreadsheet and statistics page.
