A major crash on IH-10 Katy eastbound at N. Post Oak Road shut lanes early Thursday morning, backing up traffic in the pre-dawn commute around 5:53 AM.
Authorities responded to the scene and cleared the incident, but the delay hit drivers during one of the region's heaviest truck corridors heading into the city. N. Post Oak feeds directly into the northeast approach to downtown, so eastbound traffic felt the squeeze immediately.
This location has become a persistent focal point for crashes in Harris County. According to LTA data, IH-10 Katy eastbound at N. Post Oak recorded 29 incidents over the past 30 days—22 of them major—and 106 total incidents over 90 days. The corridor's single busiest hour is 4 to 5 PM, though crashes here occur at varied times rather than clustering in one window, which means no hour is truly safe. Over the past 12 months, this same stretch has logged 220 total incidents, including four fatal crashes.
Looking at the broader record, TxDOT CRIS public crash data shows 1,306 crashes within about a quarter-mile of this location since January 2020, with "Failed To Control Speed" recorded by investigating officers as the most common contributing factor across 433 of those crashes. The hit-and-run rate in this corridor stands at 13.9 percent—meaning one in seven crashes involved a driver who didn't remain at the scene.
If you're heading eastbound on IH-10 and encounter delays this morning, I-610 loop, Westpark Tollway to the west, or Washington Ave and Memorial Dr for inner-loop segments offer relief. Check real-time conditions before you merge; the corridor can back up hard once a lane closes during the early morning push.
Weather was overcast and 78 degrees at incident time, so road conditions weren't a factor in this one. The road cleared as responding personnel wrapped up their work, and traffic gradually returned to the normal flow of the early-morning commute.
