About this crossing
San Luis I is the downtown crossing between San Luis, Arizona and San Luis Río Colorado, Sonora, open 24 hours for cars and pedestrians. Commercial trucks use San Luis II, the separate cargo port east of town.
Quick answers
Is San Luis I open 24 hours?
Yes, at port level — CBP lists the crossing open around the clock for cars and pedestrians. Individual lanes keep their own schedules: CBP’s notice puts Ready Lane at 6 a.m. to midnight, and any lane can close within the port’s hours, so check the live state above.
Can commercial trucks use San Luis I?
No. This is the passenger and pedestrian port; the corridor’s trucks use San Luis II, the commercial-only crossing east of town on the SR 195 trade route. Don’t route a truck downtown on the strength of this page’s car wait.
Does San Luis I have SENTRI?
Yes — CBP reports a separate SENTRI car wait here, alongside General and Ready. SENTRI requires enrolment in CBP’s trusted-traveller program; Ready Lane takes RFID travel documents and is a different program.
SENTRI and Ready Lane
CBP reports General and SENTRI car waits, with Ready fields for both cars and pedestrians. CBP’s port notice gives Ready Lane hours of 6 a.m. to midnight — a schedule, not a promise the lane is open now, so go by the live lane state above.
The port
The port at 431 Main Street was built in 1984 and is mid-rebuild: a $355 million modernization began in May 2023, sixteen new northbound vehicle lanes opened in March 2026, and GSA projects substantial completion in spring 2029, with the port operational throughout. The City of San Luis publishes street cameras near the crossing — views only, with no wait numbers or timestamps.
Busy times
In 2025 the San Luis port handled about 3.6 million US-bound personal vehicles and 2.5 million pedestrians (port-level BTS counts covering both San Luis facilities). December was the busiest driving month.
