Its northern end is the border with the San Luis Province; in that province it is called Provincial Route 55. It crosses the FCDFS tracks in the city of Victorica, and Provincial Route 10 about 40NaN0 further south. It runs south through the town of Carro Quemado, being asphalt until Provincial Route 14 in the El Durazno area.
