A major accident at FM 521 Road and Southern Colony Avenue in Rosenberg brought traffic to a standstill Friday morning. The crash happened around 7:05 AM on what's already shaping up as a particularly collision-prone day at this intersection.
This location has become a frequent trouble spot. According to LocalTrafficAccidents.com data, FM 521 at Southern Colony has logged 25 incidents over the past 30 days—the vast majority classified as major. Over a 90-day window, the count climbs to 49 incidents. Fridays appear especially problematic here; state crash records show 10 incidents occurred on Fridays over the past 90 days, making it the single busiest day of the week at this intersection.
The timing of crashes at this location follows an unusual pattern. While the single busiest hour is midnight to 1 AM, with 5 crashes recorded during that window, collisions here don't concentrate in one peak period—they're scattered across the day and night, which means commuters can't predict a "safe" window.
Fort Bend County overall saw 1,110 incidents in the past 30 days with no fatalities, but this particular intersection's concentration of crashes stands out. Per TxDOT CRIS public crash records, the corridor has logged 4 crashes since January 2020, with contributing factors as recorded by the investigating officer showing "Animal On Road - Wild" as the leading documented factor, cited in 1 crash. The hit-and-run rate at this location sits at 0.0%.
Weather conditions at the time of Friday's incident were clear—78 degrees with no precipitation—so wet roads or poor visibility weren't a factor in this particular crash.
If you're heading through Fort Bend this morning, plan for delays around FM 521 and Southern Colony. The incident should clear as crews work the scene, but with the intersection's recent history, expect heightened caution from other drivers passing through the area once lanes reopen.
