Westbound lanes remain impacted as emergency crews work the scene. Drivers heading toward Katy should expect significant delays and consider using alternate routes.

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.
