A major crash brought traffic to a crawl on IH-45 North southbound at the IH-10 Katy interchange at 1:34 PM on Saturday, February 28, 2026, creating significant delays across the corridor during the afternoon commute period.
The collision occurred at one of Houston's busiest freeway junctions, where thousands of vehicles merge daily between the northbound and southbound lanes of IH-45 and the eastbound and westbound directions of IH-10. With the crash happening on a Saturday afternoon—typically heavy with recreational travelers heading toward downtown or the surrounding areas—backup extended well beyond the immediate accident site. Drivers heading southbound on IH-45 faced substantial slowdowns that rippled onto the Katy Freeway itself. Those looking to avoid the mess could divert west on IH-10 toward the Westpark area, take the Hardy Toll Road northbound as an alternative route, or use surface streets through the feeder roads to bypass the interchange entirely.
This stretch of IH-45 at IH-10 has long been a pressure point in Houston's freeway network. The interchange sits just north of downtown and serves as a crucial connector for traffic flowing between the northern suburbs and the central business district. The area handles some of the heaviest traffic volumes in Harris County, with daily congestion a common occurrence even during normal conditions. Major shopping centers, office complexes, and residential neighborhoods feed traffic into this intersection around the clock.
The southbound direction of IH-45 bore the brunt of the impact. As of the latest TranStar reporting, the incident remained active in the area. Drivers heading south toward downtown should expect extended travel times and plan for significant delays. The spillover effects likely reached adjacent highways, particularly IH-10 eastbound and the feeder roads surrounding the interchange. Those commuting through this corridor should anticipate at least 20 to 30 minutes of additional travel time and consider rerouting if possible.
