The Puerto Rico Highway 52 (PR-52) is a major toll road in Puerto Rico today known also as the Autopista Luis A. Ferré, it was formerly known as Expreso Las Americas. It runs from PR-1 in southwest Río Piedras and heads south until it intersects with highway PR-2 in Ponce. At its north end, the short PR-18 continues north from PR-52 towards San Juan. This short segment is known as Expreso Las Americas, the only segment of the route still unofficially bearing this name, since PR-18 is officially named Roberto Sánchez Vilella Expressway. The combined route of PR-18 and PR-52 is concurrent with the unsigned Interstate Highway PRI-1. PR-52 is a toll road. Toll stations are located in Caguas, Salinas, Juana Díaz, and Ponce.
PR-52 is Puerto Rico's longest and second most traveled tollway. The road is mostly a 2-lane road in each direction. The section between the Caguas toll and the town of Salinas goes across the Cordillera Central, resulting in a more curvy and hilly section than the other sections of the highway. It also experiences more fog and lower visibility than the rest of the road due to the altitude. The speed limit is also reduced in the area.
Puerto Rico's only rest area is on this expressway. The rest area, however, has no relief, vending, or service facilities such as a restaurant or a gas station. The rest area does include an important monument, the Monumento al Jíbaro Puertorriqueño. The whimsical Tetas de Cayey are visible from this rest area as well.
The building of this 108-kilometre (67 mi) expressway took place during the administration of governor Luis A. Ferré, who was trained as a civil engineer himself.  It was built at a cost of $125 million. PR-52 was Puerto Rico's first toll road ever. Construction for this road started in October, 1968. It was then named Autopista Las Americas, and it was planned to run from San Juan to Ponce. On December 9, 1993, Law 118 was enacted which renamed the roadway Autopista Luis A. Ferre. The expressway is currently the longest in the island, but this will change when the 83-km-long PR-22 extends to Aguadilla. In March 1969 the roadway became a tolled expressway. The Puerto Rico Highway and Transportation Authority reports that tolls were added to the highway to speed up its construction. The road was completed in 1975.
