La Cuarenta

National Route 40, also known as RN40 or "Ruta 40", is a route in western Argentina, stretching from Cabo Vírgenes near Río Gallegos in Santa Cruz Province in the south to La Quiaca in Jujuy Province in the north with approximately 5194 km length. The route parallels the Andes mountains. The southern part of the route, by now largely paved, has become a well-known adventure tourism journey, and there are plans to pave the whole road.
