A major crash at Westheimer Road and W Sam Houston Tollway North disrupted morning traffic around 7:40 AM on Wednesday, July 01, 2026, creating significant delays in an intersection that's become one of the region's most crash-prone.
Responding officers worked to clear the scene, but the incident added to what's already a troubling record at this location. According to LocalTrafficAccidents.com data, this intersection has logged 63 incidents over the past 30 days—with 31 of those classified as major crashes. Over the past 90 days, the count climbs to 207 total incidents, 130 of them major.
This isn't a one-time fluke. TxDOT CRIS public crash records show 1,234 crashes within about a quarter-mile of this intersection since January 2020. Contributing factors as recorded by the investigating officer, per TxDOT CRIS, show that "Failed To Control Speed" is the most common factor, cited in 471 of those crashes. Hit-and-run incidents also occur regularly here—11.3% of the crashes involve drivers who left the scene.
The timing pattern at Westheimer and W Sam Houston Tollway North is diffuse rather than concentrated. While the single busiest hour is 6-7 PM, with 14 crashes recorded during that window, crashes here happen at varied times throughout the day and week. Mondays have been the worst day over the past 90 days, with 23 incidents.
Wednesday morning's clear skies and 87-degree temperature provided good visibility, so weather wasn't a factor in this particular crash. Still, the frequency of incidents here—whether in clear conditions or rain—underscores what the numbers reveal: this intersection sees collision activity at rates that dwarf typical traffic corridors in the region.
Harris County as a whole logged 17,927 incidents over the past 30 days, with 29 fatal crashes. This single intersection represents a disproportionate share of that burden.
Authorities cleared the scene and traffic resumed normal flow. Drivers using Westheimer Road or approaching the W Sam Houston Tollway North should expect residual congestion as the corridor recovers from the incident response.
