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.

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.

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.
