A fatal traffic collision shut down portions of the Katy Freeway near Greenhouse Road early Sunday morning, March 01, 2026. The crash was reported at 5:25 AM on the westbound side of the highway in Harris County, creating a major incident during the typically lighter early morning hours.
Westbound lanes remain impacted as emergency crews work the scene. Drivers heading toward Katy should expect significant delays and consider using alternate routes. The feeder road parallel to the Katy Freeway offers some relief, though it will likely experience heavy backup as well. Drivers can also divert to Bellaire Boulevard or use the surface streets through the surrounding neighborhoods, though those routes will also see increased traffic as word spreads of the closure.
This stretch of the Katy Freeway near Greenhouse Road carries substantial volume throughout the day, with the westbound direction particularly congested during morning rush hour. The area sits in a densely populated part of Harris County, with major intersections and commercial zones nearby. While early Sunday morning typically sees lighter traffic than weekday commutes, the incident's severity is causing the freeway to back up significantly as first responders manage the scene.
The fatality marks a tragic start to the weekend for the Houston area. Westbound traffic is heaviest at this hour as early travelers and commercial vehicles head toward Katy and points west. Drivers should avoid the area entirely if possible and check traffic apps for real-time updates before heading out. Those who must travel westbound on I-10 should allow extra time and prepare for extended delays as crews clear the scene and investigate the collision.
