A major crash at South Dairy Ashford Road and Westheimer Road shut down the intersection early Friday morning, August 14, at 5:27 AM. Responding officers cleared the roadway, but the collision adds to a troubling pattern at this location.
This intersection has become a frequent flashpoint for crashes. According to LocalTrafficAccidents.com data, 18 incidents have been recorded here in the past 30 days—10 of them major. Over the past 90 days, the count climbs to 126 total incidents, with 56 classified as major. The 12-month total reaches 287 incidents, 137 of them major.
The data underscores a persistent issue. While crashes occur at varied times throughout the day, the single busiest hour is 5 to 6 PM, when 12 crashes have been recorded.
