Rio Grande Rio Bravo winds through a complex landscape of international commerce and conservation at the southern edge of Texas. This 2002 update, based on earlier surveys, captures the critical infrastructure of the border, including the Progreso Toll Bridge and US Customs Immigration facilities connecting Progreso with Nuevo Progreso. The map illustrates a highly managed hydrological environment, where the Llano Grande North Floodway and Main Floodway intersect with extensive irrigation systems like the Main Supply Canal.
