History The Trail of the Ancients was made a Utah state byway about 1990. The Trail of the Ancients Scenic and Historic Byway was designated a Colorado Scenic and Historic Byway in 1994. The Trail of the Ancients was designated a National Scenic Byway on September 22, 2005 by the U.S. Secretary of Transportation and the Federal Highway Administration. The designation was the first National Scenic Byway that totally focused its sites' archaeological qualities. New Mexico and Arizona Arizona and New Mexico are applying to have the portions of the Trail of the Ancients in their states designated National Scenic Byways. This would include the Navajo National Monument and the Canyon de Chelly National Monument in Arizona, and Chaco Culture National Historical Park in New Mexico. When all four states have official national designations the Trail of the Ancients will acquire the highest status for roads, All-American Road. The New Mexico Trail of the Ancients was made a New Mexico Scenic Byway after July 13, 1998 and by 2013.
