GSA Announces Opening of 16 Northbound Vehicle Inspection Lanes at the San Luis I Land Port of Entry

Port modernization and expansion project doubles vehicle inspection capacity and enhances security

SAN LUIS, Ariz. – Today, the U.S. General Services Administration (GSA) and U.S. Customs and Border Protection (CBP) announce the opening of 16 new northbound vehicle lanes at the San Luis I Land Port of Entry (LPOE) beginning Friday, March 27, 2026.

“The modernization of the San Luis I Land Port of Entry is an investment in the future of Arizona and the entire U.S.-Mexico border region,” said Acting Public Buildings Service Commissioner Andrew Heller. “These new vehicle inspection lanes, along with the other improvements being made, will create a more resilient port that can meet the growing demands of cross-border travel for years to come. GSA is proud to support this vital infrastructure project.”

The addition of these 16 privately owned vehicle (POV) lanes marks a major milestone, doubling the number of northbound lanes. This expansion will dramatically increase vehicle inspection capacity, improve security, alleviate congestion, and boost the local economy. As the second-busiest non-commercial port in Arizona, San Luis I currently serves 3 million drivers and 2.5 million pedestrians annually.

“This expansion will significantly increase inspection capacity, strengthen border security, support economic growth, and provide a more efficient crossing experience for residents of San Luis and Yuma County, as well as millions of travelers who depend on this vital port each year,” said CBP Acting Director of Field Operations for Arizona Carlos Gonzalez.

The new northbound lanes include two shade canopies providing the traveling public, CBP officers, and their service animals with 16,000 square feet of shade protection. During the summer, temperatures in San Luis can exceed 110° Fahrenheit, some of the hottest conditions in the United States.

This work is part of a larger $356 million modernization and expansion project. The project will transform the port by replacing the original 1984 facility with all-new, efficient, state-of-the-art facilities aimed at reducing the port’s energy use and operational costs. 

To ensure efficient port operations in the desert environment, the project incorporates advanced building systems; insulation materials; and efficient heating, ventilation, and air conditioning systems. It also includes a new 21,000-square-foot pedestrian inspection building, which will increase the number of inspection booths from 10 to 14 and improve the flow of pedestrian traffic. The all-electric design includes a substantial solar panel installation and a microgrid system with battery storage, enabling the port to operate 24 hours a day, 7 days a week, independent of the electric grid,  underscoring President Trump’s commitment to achieving energy independence. Furthermore, the project seamlessly incorporates the latest inspection technology to support CBP’s security mission.

Construction is scheduled to last through Spring 2029, with the port remaining fully operational for the duration. Once complete, the new San Luis I Land Port of Entry will provide the traveling public with an enhanced experience that facilitates travel and commerce and better connects the San Luis border communities.
