1956 Map of Progreso

About this map

The Rio Grande defines the southern boundary of this landscape, its winding course marked by oxbow remnants and named land parcels like the Horcon Tract and Rosario Banco No 31. This mid-century survey reveals a highly engineered agricultural environment where the Main Floodway and North Floodway manage the river's power. The settlement of Progreso serves as a hub for both transportation and trade, situated near the Old Railroad Grade and the international crossing at the Progreso Toll Bridge. Infrastructure for the Mercedes District Settling Basin and numerous irrigation features like the Elevated Ditch networks underscore the region's reliance on water management. Smaller communities such as Relampago and Toluca are visible, alongside local landmarks like the San Pedro Ranch and the High Sch at Progreso.
