A major crash on the North Sam Houston Tollway westbound at Greens Crossing Boulevard brought morning traffic to a crawl around 7:03 AM Thursday, July 9th. The incident hit during peak commute hours on a stretch of highway that's already seeing heavy collision activity.

Responding officers worked to clear the roadway as westbound traffic backed up significantly. The crash occurred in clear conditions on a Thursday morning when the corridor typically handles substantial volume.

This incident adds to a notable pattern on this segment. According to LocalTrafficAccidents.com data, the North Sam Houston Tollway westbound at Greens Crossing has logged 13 incidents in the past 30 days, with 8 classified as major. Over the past year, the corridor has recorded 72 total incidents, 44 of them major, along with 2 fatalities.

State crash records paint a broader picture of driver behavior here. Per TxDOT CRIS public crash records, this corridor has seen 452 crashes since January 2020. The most commonly recorded contributing factor across those crashes is "Failed To Control Speed," cited in 180 incidents—a significant portion of the corridor's collision history.

Thursday's crash underscores the ongoing challenge at this location. The data shows crashes are the dominant incident type here, and major collisions account for a substantial share of the activity. While Mondays have historically recorded the highest incident count at this location, Thursday mornings remain busy periods on the corridor.

Drivers heading westbound on the Sam Houston Tollway should anticipate delays in this area and consider alternate routing if possible. Clear skies at the time of the crash mean weather was not a contributing factor to road conditions. The roadway should clear following standard incident response procedures, but commuters should monitor traffic updates for current status.

This is an active incident. Check back for updated information as conditions change.
