Port of Entry

Port San Antonio

Ports of entry within the state of Texas accounted for nearly $740 billion in international trade in 2018. Texas’ location, geography and growing economy offer a multitude of trade opportunities with other states and countries. Texas has 29 official ports of entry that serve as critical gateways to global trade, including seaports, inland ports and border crossings. Each Texas port of entry contributes to state and local economies in a unique way.

About the Port of San Antonio

Port San Antonio, one of Texas’ two intermodal logistics facilities, connects air, ground and rail, allowing businesses to take advantage of trade via all three modes of transportation. Logistics are just a part of the port’s growing business activities, which include major employers from aerospace, cybersecurity and applied technology as well as the U.S. Department of Defense.

Port San Antonio, located on the southwest side of the city of San Antonio, was created in 1995 as a result of the federal government’s decision to close Kelly Air Force Base.

Growing Strong

Port San Antonio's layout, location and structure differ somewhat from typical ports in our state, providing:

Convenient access to three interstate highways (IH-10, IH-35, and IH-37)

11,500-foot runway with large aircraft capability

1,900-acre campus

350-acre, rail-served site

As a tenant at Port San Antonio since 1998, Boeing Company’s Global Services and Support has invested more than $240 million on one of the world’s largest military aircraft maintenance, repair and overhaul facilities.

Intermodal Logistics Facility

Port San Antonio is one of Texas’ two intermodal facilities, making it different from traditional ports. Here’s how it works:

1. Parts come into port via air, rail or truck.

2. Parts are assembled at port facilities into larger components.

3. Components head to their next destination via air, rail or truck.

Job Sectors

The port’s largest job sector is made up of multiple Air Force national headquarters under the U.S. Department of Defense and employs about 5,100 professional, administrative and senior-level/uniformed personnel. The next largest civilian job sector is aerospace, which employs about 3,215..
