About this map

The industrial and transportation network of the Rio Grande Valley is defined here by the confluence of major highways and a complex irrigation system. Harlingen and San Benito dominate the southeastern corridor, connected by the high-volume routes of US Highway 77 and 83. The landscape is segmented by an extensive network of waterways essential to regional agriculture, including the Harlingen Main Canal, Line V Canal, and numerous numbered channels like Number Seven Canal.

Residential growth is evident in established communities and newer developments such as Avondale, Primera, and Palm Valley. Significant infrastructure like the Valley International Airport and the City of Harlingen Reservoir highlights the area's role as a regional hub. The meandering path of the Arroyo Colorado provides a natural contrast to the grid-like precision of the surrounding canals and suburban expansions toward Rangerville and Combes.
