A major accident shut down northbound SH 99 at S Mason Road in Richmond early Sunday morning, June 14, 2026, forcing crews into a full-scale response at 1:19 AM.
The crash hit during the quietest hours of the week—a time when you'd think the road would be clear. Instead, emergency responders were dealing with serious damage and significant lane closures that kept the corridor tied up through the overnight period.
The wreck underscores a broader pattern on this stretch of SH 99. According to LocalTrafficAccidents.com data, six major incidents have struck the same location in just the past 30 days. Over the past 90 days, the corridor has logged 14 major crashes—a rate that puts this intersection in consistent rotation for incidents despite the relatively light volume on overnight weekend hours.
The incident occurred under clear skies at 80 degrees, ruling out weather as a contributing factor. Still, the location itself tells a story. Texas Department of Transportation crash records dating back to January 2020 show 92 crashes within about a quarter-mile of this location, with "Failed To Control Speed" recorded as the most common officer-noted contributing factor across 35 of those incidents, per TxDOT CRIS public crash records. That pattern has held steady even as the corridor continues to generate new incidents week after week.
Fort Bend County saw 751 incidents across its 30-day reporting window, with one fatality. This particular crash, while major, did not result in a fatal outcome.
The wreck cleared in the early morning hours, and northbound traffic resumed normal flow as daylight approached. No further delays were reported on the corridor as of late Sunday morning.
