A car on southbound I-35 reportedly careened down an embankment just south of the Oklahoma River overpass and struck a train on the tracks below Saturday, triggering a major emergency response that backed up traffic past downtown for hours. Officials confirmed that one person died.
Oklahoma Highway Patrol troopers responded to the reported crash on southbound I-35, according to okcfox.com. Emergency responders were on scene as troopers began investigating how the vehicle careened down an embankment to the railroad tracks. The outlet reported the crash occurred in the southbound lanes of I-35 in Oklahoma City, with the resulting response causing traffic backups that stretched south past downtown.
A Corridor Built for Heavy Traffic and Heavy Rail
The stretch of highway involved is no minor side road. Interstate 235, also known as the Centennial Expressway, is a 5.4-mile corridor that carries 115,000 vehicles daily, according to data reported by ENR. It is a north-south route through Oklahoma City.
Beneath those overpasses near downtown run tracks operated by BNSF Railway, which handle an average of 49 freight trains per day, per the same ENR reporting. Some of those trains routinely carry crude oil and industrial chemicals through central Oklahoma City, according to OK Energy Today. The presence of those materials is one factor in assessing incidents near the tracks.
Known Congestion and Crash History Along the Corridor
Southbound I-235 near Sheridan Avenue is part of the corridor just south of downtown. The nearby I-235/I-35/I-40 interchange complex has also been identified as a bottleneck, with queuing reported near the junction.
A vehicle rollover into a ditch off I-235 was reported in April 2025. The corridor also includes elevated flyover ramps and has undergone lane construction.
Infrastructure Built to Handle a Complex Intersection
The physical crossing point of highway and rail line beneath I-235 was itself the product of a major engineering project. In 2018, the Oklahoma Department of Transportation completed a $17.5 million replacement of the BNSF railway bridge spanning I-235, using self-propelled modular transporters to roll two 2,000-ton steel truss spans into place over a single weekend, according to a report cited by the Federal Highway Administration. The project used modular transporters to move fully assembled bridge structures over an active interstate.
Oklahoma Highway Patrol troopers are investigating Saturday's crash, while the incident affected the rail right-of-way below the highway.
What Investigators Still Don't Know
Beyond the confirmed death, key details of Saturday's crash remain unclear, including what caused the vehicle to leave the roadway and go down the embankment, and whether anyone aboard the train was hurt. If Oklahoma Highway Patrol investigators determine the driver acted recklessly, the case could fall under Oklahoma's reckless driving statute, 47 O.S. ยง 11-901, which defines the offense as operating a vehicle in a careless or wanton manner without regard for safety and carries penalties of 5 to 90 days in jail and fines up to $500 for a first offense, according to the Urbanic Law Firm.
Train-vehicle collisions remain a safety concern nationwide. As Oklahoma Highway Patrol troopers continue piecing together what happened on the overpass above the BNSF tracks, the crash serves as a reminder of how tightly intertwined Oklahoma City's freeway and rail corridor really are.
