## About the Port
The **Port of Brownsville** (UN/LOCODE: **USBRO**) is a deep‑water, multipurpose seaport located at the southern tip of Texas, United States. Situated on the western shore of the **Rio Grande** where it meets the **Gulf of Mexico**, the port lies at **25.9° N latitude and –97.48° W longitude** and operates in the **America/Chicago** time zone (UTC‑6/UTC‑5 DST). Managed by the **Port of Brownsville Navigation District**, the facility is strategically positioned as the most southerly deep‑water port in the United States, offering direct access to the **Panama Canal** and the **Atlantic‑Pacific trade corridor**.
Key operational statistics (2023 data) include:
| Metric | Value |
|--------|-------|
| **Draft (at optimal tide)** | 45 ft (13.7 m) |
| **Berth length** | 3,400 ft (1,036 m) total |
| **Annual cargo throughput** | ~ 6.3 million short tons |
| **Primary commodities** | Steel, bulk aggregates, containers, project cargo, and agricultural products |
The port’s geographic advantage—just 30 nm from the Mexican border and 70 nm from the Gulf Intracoastal Waterway—makes it a pivotal node for **U.S.-Mexico cross‑border trade**, especially for manufacturers in the **Rio Grande Valley** and the **South Texas** industrial corridor.

## History
The origins of the Port of Brownsville trace back to the late 19th century when the **St. Louis, Brownsville & Mexico Railway** opened a modest wharf to ship cotton and timber. The site’s natural deep water and proximity to the Rio Grande secured its early role as a customs point for binational trade.
- **1910‑1930** – Expansion under the U.S. Army Corps of Engineers (USACE) created the first **dredged channel** (12 ft depth) to accommodate steamships.
- **1970s** – The Texas Legislature authorized the **Port of Brownsville Navigation District** (public‑chartered authority) to modernize facilities, leading to the construction of the **South Texas International Terminal** for bulk cargo.
- **1995** – A major deepening project increased the navigational channel to **45 ft**, enabling Panamax‑class vessels after the opening of the Panama Canal.
- **2004–2007** – The **Costa Brava Terminal** (now the **Brownsville International Logistics Center**) was built, introducing container handling capabilities and a rail‑to‑ship intermodal hub.
Throughout its evolution, the port has maintained a close partnership with the **U.S. Customs and Border Protection (CBP)** and the **Mexico‑U.S. Border Trade Partnership**, fostering a seamless flow of goods across the border. The port’s historical emphasis on **project cargo**—including wind‑farm components, offshore platform sections, and heavy machinery—has positioned it as a go‑to gateway for large‑scale infrastructure projects throughout the Gulf region.
