IH-10 Katy westbound shut after 2am crash at Dairy Ashford

A major crash on IH-10 westbound at Dairy Ashford Road closed the roadway around 2:12 AM Wednesday morning, September 16, 2026. Responding officers cleared the scene, but the incident added to an already problematic stretch of freeway that's seen significant crash activity in recent weeks.

This location has become a persistent flash point for collisions. According to LocalTrafficAccidents.com data, IH-10 westbound at Dairy Ashford has logged 29 crashes in the past 30 days alone — 18 of them major. Over a 90-day window, the corridor has recorded 102 total incidents, with 53 classified as major and one fatal.

The timing pattern here is worth noting. While crashes occur throughout the day and night, the single busiest hour is 10-11 AM, when nine crashes occurred over the past month. This early-morning incident fell outside that peak window, but it underscores the reality that this location sees collisions at all hours.

Historically, the data tells an even larger story. Per TxDOT CRIS public crash records covering January 2020 to the present, the corridor has experienced 1,019 crashes within approximately a quarter-mile — including four fatalities. Contributing factors as recorded by investigating officers show "Failed To Control Speed" as the leading factor, cited in 321 crashes.

Alternate routes during the closure included I-610 loop, Westpark Tollway westbound, or Washington Avenue and Memorial Drive for inner-loop segments. By the time traffic typically builds heading into Wednesday's morning commute, the roadway should have reopened, though residual congestion was likely.

Weather conditions at the time of the incident were clear, with temperatures around 79 degrees — a factor that typically doesn't complicate recovery or investigation.

Harris County overall logged 15,297 incidents in the past 30 days, with 16 of those fatal. This single location represents roughly one-fifth of its own monthly incident count within a narrow corridor, a concentration that speaks to the frequency of collisions here regardless of time of day or weather conditions.
