San Luis I Land Port of Entry

Project Overview

The San Luis I Land Port of Entry (LPOE) is set to undergo a modernization and expansion project. The project includes site development and infrastructure, expanded northbound (NB) privately owned vehicle (POV) lanes, NB primary and preprimary inspection canopies, associated NB secondary processing, rerouted southbound (SB) POV lanes, SB primary and secondary inspection and processing building, parking and more. The project will also focus on pedestrian, administrative, and other facilities to support the U.S. Customs and Border Protection (CBP) mission.

Community Impact

The San Luis I LPOE is the westernmost Arizona port near the California border (approximately 4 miles) and is the primary crossing location for farm workers transported to agricultural fields daily across Yuma County. The port processes approximately 3 million vehicles and 2.5 million pedestrians each year. The planned 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.

In 2018, GSA partnered with EPA to provide technical planning assistance to the city of San Luis. That process involved working with community members and stakeholders to create a planning document for the city. The plan strives to improve transportation effectiveness and revitalize downtown San Luis. GSA is ensuring that the San Luis LPOE project will be designed to align with these plans.
