History

PR-103 is the old road that ran from Hormigueros, passing through the center of Cabo Rojo, until PR-101, which connects from Boquerón to Lajas. It now extends only from PR-114 to PR-101, staying within Cabo Rojo. Due to the rural nature of PR-103, Puerto Rico Highway 100 has replaced PR-103 as a faster and more convenient route to enter and exit Cabo Rojo from the north.^[4][5]

Major intersections

The entire route is located in Cabo Rojo.
