A major crash shut down northbound I-45 at SH-249 and Mount Houston Road early Sunday morning, September 13, around 4:54 AM, jamming traffic during what should've been a quiet pre-dawn hour.
The wreck tied up the corridor as crews responded and cleared the scene. No details on vehicle count or injuries were immediately available, but the incident added to a persistent pattern at this location. According to LocalTrafficAccidents.com data, this stretch has seen 14 incidents over the past 30 days — 9 of them major crashes like this one. Over the past 90 days, the corridor has recorded 43 total incidents, with 32 classified as major.
What makes this spot notable isn't the typical morning commute crush. The timing pattern here is different: most crashes at I-45 northbound and SH-249 fall outside weekday rush-hour peaks. The single busiest hour for crashes at this location is 1–2 AM, when four crashes occurred over the tracked period. Sundays themselves are the highest-incident day at this corridor, with 9 crashes logged over the past 90 days.
State crash records paint a fuller picture. According to TxDOT CRIS public crash records, this quarter-mile stretch has recorded 605 crashes since January 2020, including 8 fatalities. Contributing factors as recorded by investigating officers show "Failed To Control Speed" as the leading factor, cited in 252 crashes. Hit-and-run incidents account for 11.8% of all crashes here — 163 of the 1,382 vehicle units involved.
Conditions at the time of this morning's crash were scattered clouds and 79°F, so weather wasn't a factor.
If you're heading north on I-45 through this area, consider detouring via the Hardy Toll Road, SH-249 northwest, or local routes using Airline Drive. Check current conditions before you leave — the corridor should clear, but early-morning incidents can linger longer when traffic volume picks up around dawn.
