The Rio Grande City Port of Entry is located at the Rio Grande City – Camargo International Bridge. The bridge is owned, operated and maintained by the Starr Camargo Bridge Company.

For much of the 20th century, a small ferry operation connected the cities of Camargo and Rio Grande City. Finally in 1966, a bridge was built by the Starr Camargo Bridge Company. and a new border inspection station was built at that time. The station was upgraded in 2000.
