The incident hit a freeway that's been running hot all month.

What's particularly telling about this location: even on a Sunday morning, when most freeways are at their quietest, this corridor delivered a major incident.

But this freeway doesn't take weekends off. Wednesday is historically its worst day with 16 incidents in 90 days, yet incidents happen every single day of the week.
Sunday's weather was overcast and 83 degrees—conditions that wouldn't typically elevate crash risk—but the corridor's profile suggests something structural about this stretch. In the past 12 months, W Sam Houston Parkway N has recorded 91 total incidents, 39 of them major. That's not random variance. That's a pattern.
