A major crash on I-10 Katy westbound at Dairy Ashford Road brought heavy delays to the corridor around 5:59 AM on Thursday, July 23, 2026, during the early-morning commute window.
Responding officers worked the scene as eastbound traffic in the area slowed significantly. Westbound drivers faced considerable backup as crews cleared the wreckage.
This stretch of I-10 between Dairy Ashford and the downtown interchange has seen a surge in crashes over the past month. According to LTA real-time incident database, the corridor recorded 32 incidents in the last 30 days—16 of them major—including one fatal crash. Over the past 90 days, that count climbs to 98 total incidents, with 47 classified as major. The pattern extends further back: in the past 12 months, this location has seen 191 crashes, 102 major and 5 fatal.
Thursdays are the busiest day for crashes here. LTA data shows 24 incidents on Thursdays over the past 90 days. While the single peak hour is 5–6 PM (with 8 crashes during that window), crashes occur throughout the day and at varied times, suggesting no concentrated commute window entirely drives the corridor's incident volume.
State crash records paint a consistent picture across a longer timeframe. Since January 2020, TxDOT CRIS data shows 976 crashes within about a quarter-mile of this location, with 4 fatalities. Contributing factors as recorded by the investigating officer, per TxDOT CRIS, show "Failed To Control Speed" as the leading factor, cited in 308 crashes. The hit-and-run rate at this corridor stands at 11.5%, accounting for 240 of the 2,091 units involved in crashes over that period.
If you're heading west on I-10 this morning, consider using I-610 loop, Westpark Tollway heading west, or Washington Avenue and Memorial Drive for inner-loop segments as alternates while crews work to clear the roadway.
Conditions at the time of the crash were broken clouds and 83°F—clear weather that did not appear to be a contributing factor to this incident.
