I-45 northbound at Mount Houston Road crash; 21 incidents in 30 days

September 14, 2026 at 10:52 AMBy Dennis R. Mundy, Executive Editor📍 Harris County

A crash on I-45 northbound at SH 249/Mount Houston Road around 10:52 AM Monday has created significant delays in the northbound lanes. The impact is substantial — this corridor has become increasingly volatile, with 21 reported incidents in the past 30 days alone, according to LocalTrafficAccidents.com data.

The location sits at a critical interchange where SH 249 meets the freeway. Northbound traffic is experiencing heavy backups as crews work to clear the scene. If you're headed north on I-45 through this area, consider using the Hardy Toll Road, SH 249 northwest, or local routes via Airline Drive as alternates.

What's notable here isn't just today's crash — it's the pattern. Over the past 90 days, 51 total incidents have occurred at this same corridor, with 39 classified as major. That's nearly one major incident every two days at this single location. Going back a full year, the count reaches 93 total incidents, 67 of them major. The data shows this isn't an anomaly; it's a sustained problem.

According to state crash records from the Texas Department of Transportation, 605 crashes have been recorded within about a quarter-mile of this location since January 2020. Contributing factors as recorded by the investigating officer, per TxDOT CRIS, show "Failed To Control Speed" as the leading factor, cited in 252 crashes. The hit-and-run rate here stands at 11.8%, meaning roughly one in eight crashes involve a driver who leaves the scene.

One other pattern worth noting: while the corridor averages crashes throughout the week, the LTA data shows the single busiest hour at this location is 1-2 AM, not during traditional rush periods. Sundays see the most incidents, with 11 crashes recorded over the past 90 days on that day alone. Today's Monday-morning crash follows a different rhythm than the location's historical norm.

Weather at the time of the crash was clear — 94 degrees and sunny — so conditions weren't a complicating factor. Harris County overall has recorded 15,488 incidents in the past 30 days, including 18 fatals.

Check real-time updates as the scene is cleared. Expect delays to persist while responding officers work through the incident protocols.
