A major crash brought congestion to West Sam Houston Parkway North at Hammerly Boulevard early Saturday morning. The collision occurred at 4:07 AM on May 23, 2026, during a period of heavy rain that left road surfaces slick across the region.
The crash hit during the off-peak hours, but Sam Houston Parkway North @ Hammerly carries a pattern of incidents that puts it in the highest-traffic-impact tier. According to LocalTrafficAccidents.com data, the corridor logged 50 incidents in the past 30 days — 43 of them major collisions — and 132 total incidents over the past 90 days. While this location sees its heaviest crash activity in the 3 PM–4 PM window on weekday afternoons, Saturdays have emerged as the most incident-prone day of the week at this intersection, with 19 crashes recorded over the past three months.
The rain was a factor in the early-morning incident. TxDOT reports wet conditions contributed to more than 14,000 Texas crashes in the most recent annual reporting period. Road surfaces were still saturated from the heavy rain at the time of this collision, and visibility may have played a role in the sequence of events.
Crews responded and worked to clear the debris. The freeway saw significant disruption as lanes were tied up during the response. At 4:07 AM on a Saturday, most commuters were still asleep, but the incident still created a bottleneck for the small volume of early-morning traffic using the corridor — delivery drivers, overnight shift workers, and early risers heading out for the day.
This crash is the latest in a series of major collisions at this location. The concentration of incidents here over 30, 90, and 12-month windows underscores the operational burden this intersection places on the region's traffic network.

The roadway was cleared and traffic flow returned to normal as the morning progressed.
