I-45 northbound crash at Mount Houston snarls morning commute

A major crash on I-45 northbound at SH 249/Mount Houston Road at 6:28 AM Wednesday morning has backed up traffic on one of Harris County's busiest corridors. Responding officers are working the scene as northbound lanes remain impacted during the early commute.

The backup extends several miles as crews work to clear the wreckage. Drivers heading north toward the Woodlands and beyond should expect significant delays over the next couple of hours. If you're flexible on timing, consider waiting until mid-morning before heading out on this stretch.

For drivers who can't wait, the Hardy Toll Road offers a parallel option, or you can take SH-249 northwest and loop back around local routes via Airline Drive. Those side streets will be busier than normal, but they'll move faster than sitting in this backup.

This location has seen consistent trouble: LTA data shows 25 incidents in the past 30 days along this same corridor, with 21 of them major crashes. Looking at a longer window, the 90-day count hits 59 incidents with 47 rated major. The historical record at this specific stretch runs deep—according to state crash records from the Texas Department of Transportation, 605 crashes have occurred within about a quarter-mile since January 2020, with 8 of them fatal.

Contributing factors as recorded by investigating officers per TxDOT CRIS show "Failed To Control Speed" as the leading factor, cited in 252 crashes along this corridor over that same period. Hit-and-run incidents also account for 11.8% of the crashes here—163 of 1,382 vehicles involved were never identified at the scene.

Weather conditions at the time of this morning's crash were clear—broken clouds and 78 degrees—so visibility wasn't a factor. But speed control issues remain the persistent pattern in this area.

One piece of interesting data: despite the morning-hour timing of today's crash, this corridor doesn't follow the typical weekday commute-peak pattern. According to LTA data, the single busiest hour here is actually 1-2 PM in the afternoon. Sundays see the highest incident count overall—13 crashes in a 90-day period compared to other days of the week.

Stay patient out there. This road should clear within a couple of hours as cleanup continues, but expect residual delays even after the initial backup clears.
