Fort Bend County — one of the fastest-growing counties in Texas — encompasses Sugar Land, Missouri City, Richmond, Rosenberg, Katy (partial), and Fulshear. The county's explosive growth has placed enormous strain on its road network, with many formerly rural corridors now handling suburban traffic volumes.

SH-6: Fort Bend's Deadliest Road
State Highway 6 dominates the crash statistics in Fort Bend County with 4,687 crashes and 18 fatalities between 2020 and 2024. The highway serves as the primary north-south artery through Sugar Land, connecting to Harris County and handling massive commuter traffic.
Why SH-6 Is So Dangerous
SH-6 combines high speeds with heavy commercial and commuter traffic, frequent access points to shopping centers, and intersections that weren't designed for current volumes. The stretch through Sugar Land near the intersection with US-59 sees particularly high accident rates.
The Fulshear Factor: Growth Outpacing Infrastructure
Fort Bend County's western communities — particularly Fulshear — have seen some of the fastest growth rates in Texas. This is reflected in the crash data for FM 1093 and SH-99.
FM 1093: The Katy-Fulshear Corridor
With 1,219 crashes, FM 1093 (Westheimer Parkway) reflects the challenges of a formerly rural road now handling suburban commuter traffic. Master-planned communities have multiplied along this corridor, but road capacity hasn't kept pace.
Grand Parkway Growth
SH-99 (Grand Parkway) ranks third with 2,895 crashes. As the outer loop has expanded and connected more communities, traffic has increased dramatically. The high-speed design combined with merging traffic from rapidly developing areas creates hazardous conditions.
