A significant traffic accident brought westbound Interstate 10 to a crawl Friday afternoon near the Dairy Ashford Road interchange in Harris County. The crash occurred at 1:15 PM on February 27, 2026, creating major delays across one of Houston's busiest corridors during peak afternoon commute hours.
The backup extended well beyond the immediate incident zone, affecting traffic on the Katy Freeway for miles. Drivers headed westbound toward Katy faced substantial slowdowns, with delays rippling onto connecting routes including the Westpark Tollway and local surface streets in the Westchester and Dairy Ashford areas. Those with flexibility should have considered alternate routes like Bellaire Boulevard or using the nearby 610 loop to bypass the congestion entirely. For commuters with a higher tolerance for surface street traffic, Energy Corridor Boulevard offered another option, though that route would see increased volume as well.
This particular stretch of I-10 West near Dairy Ashford regularly handles heavy traffic, especially during afternoon hours when cross-town commuters and commercial vehicles converge. The area marks the gateway between central Houston and the westbound corridor toward Katy and the Energy Corridor, making it a critical chokepoint during rush periods. Multiple major employers in the surrounding office parks and retail districts feed traffic onto this interchange throughout the day.
The westbound lanes bore the brunt of the impact, with the accident creating significant congestion during a time when many workers were heading home. The status of the incident—whether it had been fully cleared or remained ongoing—wasn't immediately confirmed, but major accidents at this location typically require extended cleanup periods. Drivers should have remained alert for debris and emergency personnel as crews worked to reopen all lanes.
