A major crash at Harwin Drive and West Sam Houston Parkway South brought traffic to a standstill Thursday morning around 11:25 AM, adding to a corridor that's seen collision after collision this summer.
Authorities responded to the scene and cleared the roadway, though delays rippled through the intersection during the incident. The crash happened on a clear, hot day—95 degrees with no weather complications—but the intersection's track record speaks louder than any single incident.
This crash is the latest at a location with a relentless pattern. According to LTA data, Harwin and Sam Houston has seen 35 incidents in the past 30 days alone, with 25 of those classified as major. Zoom out to 90 days, and the count jumps to 106 total incidents—73 of them major. Over the past 12 months, the corridor has recorded 229 incidents, including 147 major crashes and 2 fatalities.
The timing pattern here is worth noting for anyone who drives this stretch. While crashes occur at varied times rather than bunching into a single rush-hour crush, the single busiest hour is 4 to 5 PM, when responding officers typically handle 8 crashes on an average day.
Looking deeper into the state's crash records, contributing factors as recorded by the investigating officer, per TxDOT CRIS, show "Failed To Control Speed" as the leading factor, cited in 321 crashes at this corridor since January 2020. That's a significant pattern—more than a third of the 933 crashes documented at this intersection over the past six and a half years involve speed-related loss of control. Additionally, hit-and-run incidents account for 10.3% of crashes here, meaning roughly one in ten collisions involve a driver who leaves the scene.
Thursday's crash fits into a broader pattern that defines this intersection. Major crashes here aren't anomalies—they're the norm. For drivers who regularly pass through, the data confirms what they already know: this corridor demands extra caution, especially during the late afternoon window when incidents spike.
