1958 Map of Humacao

USGS Topo · Published 1960

About this map

Humacao serves as the focal point of this late 1950s survey, showing a landscape defined by the sugar industry and hydroelectric power. The Central El Ejemplo sugar mill stands south of the town center, connected to the coast via the Fajardo Eastern Sugar Associates infrastructure. In the mountains to the north, the Planta Hidroeléctrica de Río Blanco underscores the region's developing utility network. The map reveals the intricate neighborhood divisions within the urban center, including San Francisco, Santo Domingo, San Juan, and Santiago. Moving toward the coast, the terrain transitions into the lowlands of Punta Santiago and the Puerto de Humacao along the Pasaje de Vieques. Rural life is marked by several educational institutions, such as the Escuela Agrícola Industrial San Antonio and Escuela Julia Hernández.
