According to state crash records from the Texas Department of Transportation, the contributing factor cited most often by investigating officers at this corridor since January 2020 is "Failed To Control Speed," appearing in 420 crashes out of 897 total crashes recorded in that span.

The corridor's crash rhythm varies throughout the day. While the single busiest hour is 6–7 PM (14 crashes on average), incidents here spread across all hours. Thursdays carry the heaviest load over a 90-day window—26 crashes—but no day is safe.

Responding officers cleared lanes as they conducted their investigation. Traffic flow returned to normal after the initial gridlock eased. Specific injury counts and exact lane closure details were not immediately available.
