Puerto Rico Highway 52 (PR-52), a major toll road in Puerto Rico, is also known as Autopista Luis A. Ferré. It was formerly called Expreso Las Américas. 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 Américas, 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 runs concurrent with the unsigned Interstate Highway PRI-1. Toll stations are located in San Juan, Caguas, Salinas, Juana Díaz, and Ponce.
