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 a new port referred to as San Luis II LPOE, located approximately 8 miles to the east of San Luis I. Current pedestrian traffic at the San Luis I far exceeds its screening capacity. As a result, the U.S. General Services Administration (GSA) is building a new northbound pedestrian annex to augment current pedestrian processing capacity.

This $6 million project includes an 8,000-square-foot expansion that, upon anticipated completion in 2018, will increase processing capacity, and include new offices and public spaces.

As construction continues, the land port remains operational during the renovation and expansion. Expect changes in normal traffic patterns and stay informed via traffic advisories. Drivers are advised to monitor posted signs and continue to use available lanes.


  • The LPOE is the furthest west 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
  • Once complete, will reduce wait times during peak travel times (4-7am) during the agricultural harvest season
  • Accommodate the safe inspection of pedestrian traffic separate from vehicle processing
  • Minimize impacts to the natural environment, including vegetation, water resources and floodplains

Environmental Review: GSA has prepared a draft environmental statement.

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


  • Fall 2018
