Port Brownsville, Texas, late 1930s

Open since 1936, the Port of Brownsville is located at the southernmost tip of Texas at the end of a 17 mile (27 km) channel that meets the Gulf of Mexico at the Brazos Santiago Pass. The City of Brownsville is 2 miles (3.2 km) to the southwest, and lies adjacent to the Rio Grande River providing a convenient gateway to Mexico, which is across the river.

The traditional cargo handling methods pictured here are, of course, history.  Port website
