Weslaco and Mercedes anchor this 2019 survey of the Rio Grande Valley, characterized by a dense network of colonias and residential subdivisions. The landscape is defined by the heavy engineering of the North Floodway and Arroyo Colorado, which manage the region's hydraulic needs alongside the Valley Acres Reservoir. Significant local history is preserved in the numerous cemeteries like Campacuas Cem and Highland Memorial Cem, which serve as quiet landmarks among the growing urban footprints. Transportation corridors like Expy 83 link established city centers to outlying communities such as Mila Doce and Heidelberg. The presence of the Mid Valley Airport and the Old Reb Airport indicates the importance of regional aviation in this borderland landscape of Hidalgo County.
