This intersection is in the middle of a sustained collision pattern. According to LTA real-time incident database, Westheimer and Sam Houston Parkway South has logged 51 incidents in the past 30 days alone—28 of them major crashes like Saturday's. Over the past 90 days, the count rises to 184 total incidents, with 103 classified as major. That's a sustained clip of collisions across all hours: while the single busiest hour is 6 to 7 PM (averaging 13 crashes), crashes here occur at varied times rather than concentrating in one window, meaning commuters face collision risk throughout the day.
