Bayamón serves as a dense urban core on this 1950 survey, anchored by the Estación Bayamón and the vital industrial grounds of Central Juanita. The landscape is defined by the winding course of the Río Bayamón and its tributaries, such as Río Hondo and Caño Frío, which cut through the agricultural and residential outskirts. The map reveals a transition from traditional rural life to modernization, shown through the presence of the American RR of Porto Rico and the Hospital de Distrito de Bayamón. To the north and east, substantial Reservación Militar lands neighbor the developing barrios of Juan Sánchez and Palmas. Significant local landmarks include the Cem Nacional de Puerto Rico and smaller settlements like Sabana Seca and Hato Tejas, offering a clear view of the municipality's spatial organization during the mid-century period.
