Commonly referred to as "San Luis I", this land based port of entry located on the west side of San Luis, AZ is the primary private vehicle and pedestrian crossing between San Luis Arizona and San Luis Sonora.
With time came increased populations, increased traffic and increased workforce flow between the adjoining countries. The currently CBP facilities are in need of a remodel to accommodate the escalating numbers of passenger vehicles and on foot pedestrian traffic.
