About this map

The agricultural and transit hub of Harlingen serves as the focal point of this Cameron County survey, where the convergence of the Missouri Pacific and Southern Pacific railroads shaped the early 20th-century economy. North of the city, smaller settlements like Primera, Avondale, and Combes are connected by a growing grid of farm-to-market routes such as Santa Rosa Road. The landscape is defined by the winding course of the Arroyo Colorado and the intricate seasonal waterways of the Resaca De Los Fresnos to the south.

Near the river banks, Arroyo Park and the local Fairgrounds indicate established community spaces, while the Palmetal Sch. serves the outlying rural population near Palmetal. This 1932 edition, compiled from early aerial photography, captures the Lower Rio Grande Valley's transition into an irrigated citrus and cotton powerhouse before the massive urban expansion of later decades, anchored by the nearby town of San Benito.
