Puerto Rico Highway 1 (PR-1) is a highway in Puerto Rico that connects the city of Ponce to San Juan. Leaving Ponce, the road heads east and follows a somewhat parallel route along the southern coast of the island heading towards Salinas. At Salinas, the road turns north to cut through the Cordillera Central in its approach to San Juan. Before reaching San Juan, it climbs to make its way to the mountain town of Cayey and then it winds down into the city of Caguas on its final approach to San Juan.
