A major crash shut down the North Sam Houston Tollway eastbound at John Ralston around 6:01 AM on Saturday, June 13. Responding officers worked the scene while eastbound traffic backed up significantly through the morning.
The incident marks the fifth crash at this location in the past 30 days, according to LocalTrafficAccidents.com data. Over the past 90 days, all 11 incidents recorded here have been major crashes — a pattern that distinguishes this stretch from typical corridor volatility.
Saturdays have proven to be the busiest day for crashes at this location. LTA data shows five crashes occurred on Saturdays over the past 90 days, suggesting weekend traffic patterns or driving behavior may be a factor worth monitoring. Weather conditions at the time of Saturday's crash were clear, with temperatures around 78°F.
Looking at the broader state record, TxDOT CRIS public crash records show 120 crashes within about a quarter-mile of this corridor since January 2020, including two fatalities. Contributing factors as recorded by the investigating officer, per TxDOT CRIS, show "Failed To Control Speed" as the most common recorded factor, appearing in 23 of those crashes. The hit-and-run rate at this corridor stands at 8.5% — meaning roughly one in every 12 crashes involves a driver who leaves the scene.
Authorities did not immediately release details on lane closures, vehicle count, or injury status for Saturday's crash. The road's reopening timeline was unclear at the time of this report.
