A car ended up flipped upside down nearly 100 feet below one of North Dallas's busiest highway ramps Monday evening, shutting down the connection from eastbound LBJ Freeway to northbound Highway 75 and choking off traffic at the height of rush hour.
The crash happened below the ramp that carries drivers from LBJ Freeway to northbound Highway 75 at the High Five interchange, according to NBC 5 Dallas-Fort Worth. Texas Sky Ranger footage showed the car resting upside down underneath the elevated roadway, which rises about 100 feet above ground level at that point.
The High Five was built as a five-level interchange where I-635, also known as the LBJ Freeway, meets U.S. 75. A TxDOT project newsletter said about 500,000 motorists traveled through the interchange daily when the project was completed, underscoring why a closure on one connecting ramp can ripple through a heavily used corridor. TxDOT’s completion newsletter also described the interchange as roughly the height of a 12-story building.
The station's report said TxDOT traffic cameras captured the fallout in real time, showing the closure causing a major backup just as evening commuters were trying to get home. The disruption was expected to continue for hours, per the same account, as crews worked to clear the scene beneath the towering interchange.
What We Still Don't Know
As of the NBC 5 report, officials had not released any information about injuries from the crash, nor had they said what caused the vehicle to go off the ramp. Those details remained unconfirmed at the time of reporting.
A History of High-Stakes Incidents at the Interchange
The High Five interchange, where U.S. 75 meets Interstate 635, has seen its share of dramatic closures over the years. In 2018, a tanker truck hauling a volatile resin rolled onto its side on the massive overpass after striking a retaining wall around 4:30 a.m., prompting a hazardous materials cleanup that shut down both highways for several hours, NBC 5 reported at the time. A Dallas Fire-Rescue spokesperson said at the time that no other vehicles were involved and no one was hurt in that incident.
Separately, FOX 4 Dallas-Fort Worth has reported that at least one person died and three others were hospitalized in a multi-vehicle crash involving an 18-wheeler on southbound U.S. 75 near the same interchange. That outlet said preliminary reports indicated two or three vehicles collided, though the exact cause was not known at the time. These past incidents illustrate how disruptive crashes at the sprawling interchange can be, though the available evidence does not point to any broader pattern tying them together.
The crash’s cause and outcome remain unknown, but statewide data show the broader danger of vehicles leaving the roadway: single-vehicle run-off-road crashes killed 1,353 people in Texas in 2024, about one-third of the state’s 4,150 traffic deaths that year. Those figures do not establish what happened on the High Five ramp; investigators would need to determine the circumstances of this crash. TxDOT’s annual Texas crash statistics also recorded 14,905 serious-injury crashes statewide in 2024.
For now, the focus remains on Monday's crash and the ramp closure it triggered, with commuters facing a longer-than-usual trip through one of Dallas's most tangled stretches of highway until the backup clears.
