Circuito Sur

The highway goes along the Caribbean Coast in some areas and both endpoints cross the Carretera Central.

The road enters the towns of Cabezas, Alacranes, Unión de Reyes, Bolondron, Pedro Betancourt, Torriente, and Jagüey Grande.

It then continues southeast through the towns of Real Campina and Yaguaramas, where after the new Circuito Sur bypass and the 4-I-2 split again.
