1965 Map of Rio Grande City South

About this map

The Rio Grande City riverfront defines this mid-1960s landscape, where international commerce and regional infrastructure meet along the Rio Grande. This survey highlights the complex relationship between the shifting river and the border, noting that the international boundary line was not completely defined at the time of mapping due to river changes. Critical border infrastructure is visible near the city center, including the Toll Bridge and U S Customs station. East of the city, the Missouri Pacific railroad tracks run parallel to the river, serving agricultural and industrial interests like the Gravel Pit near Olmos. The landscape is dotted with oil and gas wells, particularly near El Refugio and Los Velas, while traditional community landmarks like Olmos Cem and the Drive-in Theater reflect the social fabric of the era.
