Industrial expansion and military installations dominate the coast of northern Puerto Rico in the early 1960s, where the Río Bayamón meets the Atlantic Ocean. The landscape shows a region in transition, featuring the sprawling Fort Buchanan Military Reservation and the US Naval Radio Station (R) Sabana Seca alongside emerging residential developments like Levittown. The sugar industry’s legacy remains visible at Central Juanita, while modern infrastructure is represented by the Planta Termelectrica De Palo Seco and the San Juan Tracking Station.
