Laredo and County Government
Laredo is the county seat and principal city, containing the courthouse, county offices, international bridges, customs and logistics facilities, schools, universities, healthcare, and regional commerce.
Interstate 35 and U.S. Route 83 connect the border with inland Texas and communities farther south.
Rio Bravo and El Cenizo
Rio Bravo and El Cenizo are incorporated cities south of Laredo near the Rio Grande. Residential areas, schools, local commerce, and border roads shape these communities.
River access and travel in international-border areas require current federal, state, county, and landowner guidance.
Lake Casa Blanca
Lake Casa Blanca International State Park protects a reservoir and surrounding South Texas brush country east of Laredo. Fishing, boating, swimming, camping, hiking, and wildlife viewing are common activities.
Texas Parks and Wildlife places the park on the western edge of the South Texas Brush Country. Current water level, park alerts, and access conditions should be checked before travel.
Bruni, Oilton, and Eastern Webb County
Bruni, Oilton, and Mirando City are unincorporated communities in eastern Webb County associated with oil and gas activity, ranching, and regional roads.
Wells, pipelines, work roads, and private-property boundaries change over time, so current industry and property records are required for field operations.
Rio Grande and Brush Country
The Rio Grande forms the county’s western international boundary. Floodplain, brush, farmland, and urban areas occur along the river, while thornscrub and ranches dominate much of the interior.
Water levels, flooding, and security conditions can change, so current official information is required for river access and emergency decisions.

The color version separates Webb County from neighboring areas and helps show Laredo, Rio Bravo, El Cenizo, the Rio Grande, Lake Casa Blanca, ranches, and brush country.
Black-and-White Map
The black-and-white map retains the county outline and selected place names for grayscale printing.
Outline Map
