From American Heritage, a modern tour of America’s oldest highway.
In 1598 Oñate blazed the Camino Real de Tierra Adentro, a trail that became the most used and most significant route of commerce and culture for 300 years. At its peak the Camino Real ran 1,800 miles from Mexico City north to Santa Fe. Spaniards used the trail to settle towns and villages all along the way, Franciscans used it to spread their gospel, troops from the United States and Mexico used it for waging battles and building forts, Indians used it to fight the swelling tide of foreigners, and traders used it for commerce.
