Inaugurated on 8 July 1960 after three years of construction, this unpaved part of the National Route 40 is only suitable for all-terrain vehicles, with the exception of some months in the year when meteorological and maintenance conditions allow normal vehicles to transit. The road inclination of 4.5% and oxygen deprivation due to altitude make the crossing difficult for both vehicles and people.
