A major crash shut down IH-45 northbound at IH-10 Katy early Wednesday morning, July 29, at 2:34 AM, backing up traffic across one of Harris County's most crash-prone freeway intersections.
Responding officers cleared the scene after the initial impact, but the roadway remained heavily disrupted during the overnight period. If you're heading north on 45 this morning, expect delays even as rush hour approaches. Hardy Toll Road, SH-249 heading northwest, or local routes via Airline Drive offer alternatives, though those too may see heavier-than-normal volume as drivers reroute.
This intersection sits at a troubling crossroads for crash frequency. Over the past 30 days, LTA data shows 36 incidents at IH-45 northbound at IH-10 — 29 of them major crashes like this one. Zoom out to the past year, and the corridor has logged 283 total incidents, with 220 classified as major. The stretch draws crashes around the clock: while the single busiest hour is 4 to 5 PM (11 crashes in that window over 90 days), collisions here occur at varied times rather than clustering in any one period, which means late-night and early-morning incidents aren't anomalies.
State crash records paint a broader picture of the corridor's history. Per TxDOT CRIS public crash records, this intersection and the immediate surrounding area have recorded 1,336 crashes since January 2020, with 2 fatalities. Contributing factors as recorded by the investigating officer, per TxDOT CRIS, show "Failed To Control Speed" as the leading factor, cited in 558 crashes. Hit-and-run incidents account for 11.5% of all vehicle involvement in crashes here — 340 of 2,969 units involved.
Weather conditions at the time of the crash were clear, with temperatures at 80°F, so visibility and road surface weren't a factor in this incident.
Harris County as a whole recorded 17,441 incidents over the same 30-day period, including 29 fatalities. The IH-45 northbound at IH-10 intersection remains one of the region's highest-incident corridors, and this morning's crash is consistent with its ongoing pattern.
Commuters should check real-time traffic updates before heading out. Expect delays well into the morning commute window.
