A crash along Loop 375 West near San Marcial in South-Central El Paso left one person seriously injured Monday evening, shutting down all westbound lanes of the border highway with no estimated reopening time. Fire officials said the patient was transported Code 3, the designation used for the most urgent, life-threatening emergencies.
The collision happened along Loop 375 West, also known as Border Highway, near Paisano in South-Central El Paso, according to KTSM 9 News. The outlet reported that a fire spokesperson confirmed one person was seriously hurt and that the crash closed all lanes of traffic along Loop 375 West at San Marcial. Motorists were urged to seek alternate routes while crews worked the scene, with clearing time estimated as until further notice.
San Marcial sits at a key junction where Paisano Drive feeds directly into Loop 375, right next to the Chamizal National Memorial, according to the National Park Service. That intersection makes the stretch a heavily used connector for both local commuters and cross-border traffic moving along the highway corridor.
A Corridor Already Under Scrutiny
Loop 375 carries the formal name César Chávez Border Highway, a designation set in Texas Transportation Code Section 225.051 for the segment between Interstate 10 and Santa Fe Street, established by the 77th Texas Legislature. TxDOT and the Camino Real Regional Mobility Authority expanded the corridor into six lanes in 2014, adding two lanes across a 9-mile stretch and eventually converting what were once managed toll lanes into toll-free lanes meant to ease pressure off Interstate 10.
The highway has drawn heavy safety investment in recent years. TxDOT has installed an advanced pedestrian detection and dynamic messaging alert system along the corridor, including active warning signs at San Marcial, intended to give drivers real-time notice of unexpected hazards. In July 2026, the agency also opened Texas's first mechanical runaway truck ramp on Loop 375, a dragnet net system built to stop commercial vehicles weighing up to 90,000 pounds traveling as fast as 90 mph.
Part Of A Broader Safety Push
The El Paso Metropolitan Planning Organization adopted its Borderplex Safe Mobility Plan in November 2025 to target high-injury crash locations and steer safety improvements toward major regional corridors, including Loop 375. That planning effort comes against a stark countywide backdrop: TxDOT crash records for El Paso County in 2024 logged 18,344 total motor vehicle collisions, including 76 fatal crashes that killed 80 people and left 311 more with suspected serious injuries, per the Ruhmann Law Firm.
Monday's crash is the latest in a string of serious incidents on the corridor this summer. Hoodline previously reported on a wrong-way rollover crash that shut down connector ramps between I-10 and Loop 375, a late-July collision that killed two young men after a high-speed crash into a concrete barrier, and a multi-vehicle pileup on Loop 375 North that required a medical helicopter and snarled the East El Paso commute. Earlier this month, a motorcyclist's death in Northeast El Paso became the city's 33rd traffic fatality of 2026, a case that involved the El Paso Police Department's Special Traffic Investigations unit, which handles scene analysis and crash reconstruction whenever a collision results in fatal or life-threatening injuries.
It remains unclear what caused Monday's crash, how many vehicles were involved, or whether the Special Traffic Investigations unit has taken over the case. No timeline for reopening the closed lanes had been released as of the crash report, and officials had not indicated the injured patient's condition beyond the initial Code 3 transport.
