Puerto Rico Highway 103 (PR-103) is a rural road that connects from the PR-114, near Hormigueros, to the PR-101, in Cabo Rojo.

PR-103 is the old road from Hormigueros, passing through the center of Cabo Rojo, until the PR-101 (which connects from Boquerón to Lajas).

Therefore, the PR-100 is a road to replace PR-103 because it is a faster and more comfortable road.

[4][5] The entire route is located in Cabo Rojo.
