A major crash brought southbound traffic to a standstill on the West Sam Houston Tollway at US-290 Northwest at 8:17 AM Monday morning, August 31st.
The collision forced authorities to close lanes while responding and clearing debris. Backup extended well into the morning commute as drivers were diverted around the scene. If you're heading that direction, consider FM 1960 or Cypress-Rosehill Road for northwest segments, or Hempstead Road for inner segments.
This is the ninth incident at this interchange in the past 30 days, according to LocalTrafficAccidents.com data. Over the past 12 months, the corridor has recorded 21 total incidents, including 15 major crashes and 2 fatalities. The interchange consistently ranks as one of the region's higher-incident locations on the Sam Houston system.
State crash records from the Texas Department of Transportation show that the leading contributing factor recorded by investigating officers at this corridor has been "Failed To Control Speed," cited in 401 crashes since January 2020. The data spans nearly a thousand crashes in the immediate area over the past six years—a pattern that underscores why even a single Monday morning wreck here can ripple across the whole commute.
Weather at incident time was clear with temperatures around 85 degrees, so visibility was not a factor in this crash.
The roadway was back to normal flow by mid-morning. Harris County reported 17,560 traffic incidents in the past 30 days across the region, with 18 of those fatal.
