1946 Map of Arecibo

About this map

Arecibo stands as the primary hub along the northern coast of Puerto Rico in this mid-1940s survey, where the American Railroad of Porto Rico and the sugar-processing operations of Central Cambalache dominate the local economy. The landscape is defined by the winding course of the Río Grande de Arecibo, which feeds into the Puerto Arecibo harbor near Pta Morrillos. To the east, the extensive wetlands of Caño Tiburones contrast with the rugged, limestone-pockmarked interior to the south. This era shows a dense network of local settlements and infrastructure, including the Hospital Distrito de Arecibo and the Escuela Segunda Unidad de Bajadero, reflecting the social and industrial growth of the region before modern highway expansion altered traditional transit routes through areas like Poblado Santana and Bajadero.
