I-45 northbound at Mount Houston sees 21st crash in 30 days

A major crash shut I-45 northbound at SH 249 and Mount Houston Road around 1:40 AM on Sunday, August 23, adding to a spike in collisions at this stretch of freeway.

The incident forced traffic onto alternate routes — Hardy Toll Road, SH 249 to the northwest, or local streets via Airline Drive — as crews worked to clear the roadway. By early morning, the road reopened, though the crash marks yet another disruption on a corridor that's becoming increasingly problematic.

According to LocalTrafficAccidents.com data, this location has logged 21 incidents in the past 30 days, with 18 classified as major. Over the past 90 days, the count climbs to 43 total incidents, 35 of them major. In the last 12 months, responders have been called to 77 crashes at this intersection — a pattern that extends far beyond recent weeks. State crash records from the Texas Department of Transportation document 602 crashes within about a quarter-mile of this corridor since January 2020, including 8 fatalities.

The timing of Sunday's crash is notable. LTA data shows the single busiest hour at this location falls between 1 and 2 AM — outside the typical weekday commute window. That early-morning window has seen 5 crashes in the past 30 days, making it the corridor's peak period even though it doesn't align with rush hour.

When investigators examine the crashes that do occur here, one factor stands out. Contributing factors as recorded by the investigating officer, per TxDOT CRIS, show "Failed To Control Speed" as the leading factor, cited in 252 crashes at this corridor since 2020. That pattern suggests driver behavior plays a significant role in the frequency of incidents at this location.

Harris County recorded 18,137 incidents in the past 30 days, with 19 fatalities — putting this single intersection's 21-incident rate well above the county average for a comparable stretch. The early-morning timing, combined with the number of speed-related crashes documented over years of state records, paints a picture of a high-collision corridor that operates on a different incident calendar than most of the freeway network.

Sunday's weather — overcast skies and 83 degrees — posed no obvious environmental barrier. The road was open and conditions were clear, yet another crash landed on a location that's seen nearly eight dozen collisions in 12 months.

If you're traveling this stretch during overnight hours, expect delays and consider the alternate routes. This corridor's pattern suggests another incident is statistically likely in the weeks ahead.

**Update (2:45 AM CT):** The major crash at IH-45 North Northbound at SH 249/ Mount Houston Rd, first reported at 1:40 AM, has cleared after approximately 1 hour and 5 minutes. All lanes have reopened and normal traffic flow has resumed in the area.
