Ruta 40, Argentina

National Route 40 or RN40 (often called Ruta 40), is a route in western Argentina, stretching from Cabo Virgenes in Santa Cruz Province in the south to La Quiaca in Jujuy Province in the north, running parallel to the Andes mountains. The southern part of the route, a largely paved road through sparsely populated territory, has become a well-known adventure tourism journey.
