Trail Ridge Road is one of just two All-American Roads in Colorado. All-American Roads represent the best of the best of our scenic byways. According to the National Scenic Byways Program
To receive an All-American Road designation, a road must possess multiple intrinsic qualities that are nationally significant and contain one-of-a-kind features that do not exist elsewhere. The road or highway must also be considered a 'destination unto itself.' That is, the road must provide an exceptional traveling experience so recognized by travelers that they would make a drive along the highway a primary reason for their trip.
Colorado's other All-American Road is the San Juan Skyway, referenced in this post.
