San Luis I Land Port of Entry
The port experiences much higher traffic volumes than it was originally designed to accommodate. Furthermore, the port’s facilities are significantly undersized and require upgrading to meet the U.S. Customs and Border Protection’s current mission requirements. The modernization and expansion project will improve efficiencies and traffic flows, reduce wait times, increase CBP’s processing capacity and operational security by effectively deploying the latest technology to identify high risk activity and shipments and combat drug trafficking.
The project includes site development and infrastructure, expanding northbound privately owned vehicle lanes from eight to 16, primary and preprimary vehicle inspection canopies, and secondary vehicle processing area. Southbound privately owned vehicle improvements include expanded southbound facilities with fixed inspection infrastructure for CBP’s mission, primary and secondary inspection and processing building, and employee parking. It also includes increased pedestrian inspection lanes from 10 to 14 as well as a new administrative facility to support the CBP mission.

Environmental review
GSA conducted an environmental impact statement for the project with input from the public via public meetings and comments. The EIS documents are available for review.
Local updates
Apr. 26, 2023, GSA officials brief community stakeholders and civic leaders on the port modernization and expansion project. The slides [PDF - 6 MB] are available for review.

Bipartisan Infrastructure Law
We received $3.4 billion to invest in our nation’s infrastructure and competitiveness. The law provides funding for LPOE modernization projects that will create new good-paying jobs, bolster safety and security, and make our economy more resilient to supply chain challenges — all while serving as models for sustainability and innovation.
Visit the Arizona LPOE page for an overview of BIL projects there, as well as priorities, benefits and further information.
Sustainability opportunities
We will increase energy and water efficiency (including renewable energy and fossil fuel free measures), adhere to sustainable design principles, and minimize climate risk liabilities above the minimum performance criteria in a manner that is life cycle cost-effective.
Community impact
The San Luis I LPOE is a major regional economic engine for the city of San Luis and Yuma County, supporting its agricultural and retail industries. This project expands and modernizes the entire port, providing state-of-the-art facilities for the CBP operations in San Luis. The project will also improve efficiencies and traffic flows, reduce wait times, increase CBP’s processing capacity and operational security by effectively deploying the latest technology to identify high risk activity and shipments and combat drug trafficking.
