A major crash on the Northwest Freeway outbound at Black Guhn Road brought afternoon commute traffic to a crawl Tuesday, February 24, 2026, at 2:51 PM. Houston Police responded to the incident in Harris County, where the collision blocked lanes during one of the heaviest travel periods of the day.
Drivers heading northwest on the freeway faced significant delays stretching back several miles. The afternoon timing made this particularly problematic, as the incident struck right when school dismissal and early evening commuters were hitting the roads. Travelers with flexibility should consider diverting to parallel routes like FM 1960 or taking the Hardy Toll Road northbound as an alternative. Those heading to or from the northwest corridor might also use TX-249 as a bypass, though that route was likely seeing its own uptick in volume by mid-afternoon.
This stretch of the Northwest Freeway carries some of the Houston area's heaviest daily traffic, serving as a primary artery connecting northwest Harris County communities with central Houston. Black Guhn Road marks a busy intersection where the freeway feeds traffic from the Spring and Tomball areas. The corridor regularly experiences congestion during peak hours, making any incident here particularly disruptive to the regional commute.
The crash's impact rippled through connecting roadways, with backup likely extending well beyond the immediate area. A major incident at this location during afternoon hours typically creates spillover effects on FM 1960 and surrounding surface streets as drivers seek alternate routes. Commuters in the northwest sector should have anticipated delays extending well into the evening rush hour.
