San Luis I Land Port of Entry


The San Luis I Land Port of Entry (LPOE) is the second busiest non-commercial LPOE in Arizona, processing over 3 million vehicles and 2.5 million pedestrians each year. San Luis I LPOE was originally constructed as a multimodal port for commercial and non-commercial crossing. In 2010, commercial operations shifted to San Luis II LPOE, located approximately 8 miles to the east of San Luis I.

In November 2017, GSA broke ground on a brand new northbound pedestrian facility to augment the port's overall pedestrian inspection capacity. The new building, completed in 2018, replaced the old pedestrian facility which could no longer accommodate the current level of pedestrian travelers. The $6 million project included an 8,000-square-foot expansion that increases processing capacity, and includes new offices and public spaces.


  • The LPOE is the westernmost Arizona port near the California border (approximately 4 miles) and is the primary crossing location for farmworkers transported to agricultural fields daily across Yuma County
  • Processes approximately 3 million vehicles and 2.5 million pedestrians each year
  • Minimize impacts to the natural environment, including vegetation, water resources and floodplains

Environmental Review: GSA has prepared an environmental impact statement for the project.

Tenant Agencies: U.S. Department of Homeland Security - Customs & Border Protection, and Immigration and Customs Enforcement, and GSA.


  • Expansion of northbound pedestrian-processing facilities will increase from seven to 10 lanes, reducing screening times and increasing visitor and employee safety
  • Modernize processing equipment
  • Redesign of pedestrian circulation flow to support current U.S. Department of Homeland Security - Customs and Border Protection procedures
