A major accident brought northbound traffic to a crawl on State Highway 99 at South Fry Road in Katy at 4:55 PM Thursday afternoon. The collision occurred during the tail end of the evening commute, creating immediate backup along one of the busiest corridors in the area.
Drivers heading north on the Grand Parkway faced significant delays as emergency crews worked the scene. Commuters should have rerouted onto South Fry Road toward Cinco Ranch Boulevard or taken Westheimer Parkway as an alternative to avoid the backup entirely. For those already committed to the SH 99 corridor, the backup extended well south of the accident site, affecting traffic flow through Katy Mills and beyond.
The northbound SH 99 stretch at South Fry Road is no stranger to serious collisions. Over the past month alone, the intersection has recorded eight major incidents among 16 total crashes—a pattern that underscores the challenges this particular corridor faces during peak traffic hours. The convergence of local and through traffic, combined with rapid acceleration zones and frequent lane changes, has made this a persistent trouble spot for the Fort Bend County area.
North-flowing traffic bore the brunt of the impact Thursday evening. The incident tied up the evening commute through the 5 o'clock hour, with delays expected to persist into the early evening. Drivers heading toward Tomball or continuing north toward Houston should anticipate heavy congestion and allow extra travel time. Southbound lanes remained open, though rubber-necking likely affected overall throughput.
