Was New Mexico connected to City by El Camino Real or the Rio Grabnde?

New Mexico was connected to Mexico City by El Camino Real.

The El Camino Real de Tierra Adentro was a Spanish colonial road that connected Mexico City to Santa Fe, New Mexico. The road was established in the 16th century and was used by traders, missionaries, and settlers to travel between the two cities. The El Camino Real was also used by the Spanish military to transport troops and supplies to the northern frontier of New Spain.

The Rio Grande is a river that flows through New Mexico, but it does not connect New Mexico to Mexico City.
