Carretera Central (Puerto Rico)
The Carretera Central is a north–south central highway in Puerto Rico.
The highway runs from San Juan, the largest city in Puerto Rico, located on the north coast to Ponce, the second largest, on the south coast, via Caguas, Cayey, Aibonito, Coamo, and Juana Diaz. The highway corridor is now designated as Puerto Rico Highway 14 from Ponce to Cayey and part of Puerto Rico Highway 1 from Cayey to San Juan, although various sections of the original road have since been bypassed by the modern highways.
In 1886, it was a 134-kilometer (83 mi) route with 13 permanent bridges and 33 "casillas de camineros" (housing for road maintenance technicians).
