Historic America, thoughtfully explored.
This U.S.-only selection includes all 21 designated National Historic Trails listed by the National Park Service, the distinct American subjects in the earlier ATA historic-roads directory, and additional heritage roads and walks.
Chihuahua Trail is discussed with El Camino Real de Tierra Adentro; Cumberland Road is included as Historic National Road. California’s mission corridor is a separate entry. Cross-border routes are limited to U.S. visits.
National Historic Trails, National Scenic Trails, byways and local heritage walks have different designations. Entries identify the experience; inclusion does not imply every route is federally designated or continuously open.
Route counts describe directory entries, some of which overlap. This is a curated directory rather than a claim to list every historic road in America. Research: October 2026.
