About this crossing
The Marcelino Serna port — the Tornillo–Guadalupe bridge — is the rural crossing east of El Paso, open 6 a.m. to 10 p.m. for cars and pedestrians, with weekday-only cargo from 8 a.m. to 4 p.m. Southbound it is free; the northbound toll is collected on the Mexican side.

The bridge
The 1,274-foot bridge is owned by El Paso County on the U.S. side. It came online in stages: CBP began northbound car and pedestrian processing in November 2014, the full both-side passenger and pedestrian facilities opened on 4 February 2016, and the cargo lot followed in March 2016.
Busy times
In 2025 the port handled about 786,000 US-bound personal vehicles, 87,000 pedestrians and 37,000 trucks (port-level BTS data); December led for cars.
Quick answers
Is Tornillo open 24 hours?
No — 6 a.m. to 10 p.m. daily for cars and pedestrians, with cargo on weekdays from 8 a.m. to 4 p.m. The nearest 24-hour crossing is Ysleta; Fort Hancock, the corridor's third crossing, keeps a shorter day still, closing at 6 p.m.
Is Tornillo the same crossing as Fabens–Caseta?
Yes, practically — the Tornillo–Guadalupe bridge replaced the old Fabens–Caseta bridge in February 2016. If directions, an old listing or a map still say Fabens or Caseta, this bridge — the Marcelino Serna port — is the crossing you want.
Does Tornillo have a southbound live wait?
No. TTI's public border-wait system was under maintenance at the last 29 August 2026 check, so no southbound number is published here — the U.S.-bound waits are the only live figures for Tornillo.
