1956 Map of Rio Hondo

About this map

The agricultural and industrial character of the Rio Grande Valley is captured here during the mid-1950s, defined by an intricate network of irrigation ditches, levees, and canal dredgings. The Arroyo Colorado serves as a primary artery, supporting Port Harlingen with its nearby oil tanks and spoil banks. In the north, Rio Hondo sits at the junction of the Missouri Pacific and several elevated ditches, while the southern portion of the map is anchored by the growing city of San Benito.
