Rio Grande frontage and international border crossings define this mid-1960s landscape along the Texas-Mexico line. The river’s winding course created landmarks like Fronton Island and necessitated the US Customs Toll Bridge at the riverfront town of Roma-Los Saenz. Settlement patterns reflect the arid environment and agricultural needs, with smaller communities such as Fronton and Santa Margarita clustered near water sources or elevation changes.
