Puerto Rico Highway 12 (PR-12), also called Avenida Malecón, and Avenida Santiago de los Caballeros, is a 6.4-kilometer, limited-access highway entirely located within the city limits of Ponce, Puerto Rico, and connecting Puerto Rico Highway 14 to the La Guancha area in Barrio Playa in Ponce. It is similar to a freeway but has one traffic light near its intersection with PR-14. In addition to its northern and southern terminus, the highway has four full interchange exits: PR-52, PR-2, PR-133/Calle Comercio, and Avenida Las Américas. Since PR-12's southern terminus is at the Port of Ponce, its traffic volume is expected to grow as construction in the new Port of the Americas is completed.
