A crash with injuries brought traffic to a crawl on US-90 at S Post Oak Road Thursday morning at 8:28 AM, adding to what's shaping up to be another problematic day on a corridor that's seen repeated collisions in recent weeks.
The incident occurred during mid-morning hours on a road segment that doesn't follow typical rush-hour patterns. According to LTA data, US-90 at S Post Oak has logged 32 incidents over the past 30 days, with 15 classified as major. While the evening peak (5–6 PM) tends to see the highest concentration of crashes on this stretch, collisions here happen throughout the day at varied times, making this corridor unpredictable for commuters trying to time their trips.
Thursday itself has been the day with the most incidents at this location over the past three months, with 19 crashes recorded on Thursdays alone. The broader data tells a larger story: in the past 90 days, 137 total incidents have occurred at this intersection, 69 of them major crashes. Over the full 12-month period, the corridor has seen 280 incidents, with 163 classified as major.
State crash records paint a consistent picture of what's happening here. According to TxDOT CRIS public crash records dating to January 2020, this corridor has experienced 812 crashes within about a quarter-mile—3 of them fatal. Contributing factors as recorded by the investigating officer, per TxDOT CRIS, show "Failed To Control Speed" as the leading factor, cited in 280 crashes at this location. Additionally, the hit-and-run rate here sits at 12.8 percent, meaning roughly one in eight crashes involves a driver who leaves the scene.
Clear skies and 87-degree temperatures prevailed at the time of Thursday's incident, so weather wasn't a factor in this particular crash.
Responding officers handled the scene. Details on lane closures, traffic diversions, and estimated clearance times weren't immediately available. Drivers on US-90 should expect residual delays in the area until the incident fully clears.
This is the latest in a sustained pattern at an intersection where commuters face collision risk regardless of time of day. The data shows this is a corridor worth monitoring closely if you travel it regularly.
**Update (4:30 PM CT):** The major crash at US-90 & S Post Oak Rd, first reported at 8:28 AM, has cleared after more than 8 hours. All lanes have reopened and normal traffic flow has resumed in the area.
