North Sam Houston Tollway crash at SH-249; 56 incidents in 30 days

---

A major crash on the North Sam Houston Tollway eastbound at SH-249 Tomball Parkway brought traffic to a standstill Friday morning. The incident happened at 9:32 AM, and responding officers worked to clear the debris and reopen lanes.

This intersection sits on a stretch that's become a flashpoint for collisions. According to LocalTrafficAccidents.com data, 56 crashes have been reported here in the past 30 days alone — 46 of them major incidents. Over the past 90 days, the count climbs to 124 total crashes, with 100 classified as major. The toll extends back months: 145 total incidents in the past 12 months, 121 of them major.

The eastbound direction takes the heaviest volume of traffic heading toward Tomball and beyond, and this particular stretch has become notorious for high-speed collisions. State crash records from the Texas Department of Transportation show 372 crashes within about a quarter-mile of this corridor since January 2020. Contributing factors as recorded by investigating officers, per TxDOT CRIS, show that "Failed To Control Speed" is the most commonly cited contributing factor, appearing in 117 of those crashes over the past six years.

Friday's incident occurred under overcast skies with temperatures near 79 degrees — conditions that shouldn't have contributed to the crash, though the underlying pattern here speaks for itself. Fridays tend to be the worst day at this location; over the past 90 days, 21 crashes occurred on Fridays alone. While the single busiest hour is 6–7 PM (averaging 13 crashes), collisions here happen throughout the day at varied times rather than concentrating in one predictable window.

If you're heading toward Tomball Parkway or need to cross the North Sam Houston Tollway in this area, consider using Kuykendahl Road or Stuebner Airline as alternates until the eastbound lanes reopen and traffic flow normalizes.
