About this crossing
Santa Teresa is the New Mexico bypass around the El Paso bridges, 42 miles south of Las Cruces on NM 136. Cars and pedestrians cross 6 a.m. to 10 p.m. daily; cargo runs the same hours on weekdays only.
Cargo
Santa Teresa has three RFID-equipped commercial lanes, weekday cargo to 10 p.m., and a state-designated overweight cargo zone allowing loads up to 96,000 pounds within a six-mile radius — a regional allowance, not blanket permission for any load.
The port
The original port opened in 1992 and the current facility dates to 1997. A separate livestock crossing spans the border about one mile east — a different facility with its own page and no traveller access.
Busy times
In 2025 the port handled about 644,000 US-bound personal vehicles, 155,000 pedestrians and 172,000 trucks (port-level BTS data). December led for cars; trucks peaked in October.
Quick answers
Is Santa Teresa open 24 hours?
No — 6 a.m. to 10 p.m. for cars and pedestrians, weekdays only for cargo. The 24-hour crossings in the region are BOTA and Ysleta in El Paso, and Columbus to the west.
Does Santa Teresa have Ready Lane or SENTRI?
Ready Lane, yes — a reported car lane for RFID travel documents. SENTRI is not reported here; the region's SENTRI operations are on the El Paso bridges, where Stanton's northbound side is a dedicated SENTRI commuter lane.
Is the Santa Teresa livestock crossing the same queue?
No. The livestock facility is a separate crossing about one mile east, operated for animal shipments with no traveller access and no wait times. This page's numbers cover the road port only.
