The Rio Grande defines the international boundary between the United States and Mexico in this 2010 topographic survey of the Rio Grande Valley. The landscape is characterized by a dense network of residential subdivisions known as colonias, including Jesus Maria Colonia, Santa Amalia Colonia, and Los Leones Colonia, which sit alongside established communities like Relampago and Progreso. This era shows significant infrastructure supporting the border economy, most notably the Progreso Toll Bridge and the Progreso Airport.
