A major traffic collision brought northbound lanes on Interstate 45 to a standstill Thursday night at 9:05 PM near Exit 59. The crash tied up the busy corridor during the evening commute window, creating backups that extended well beyond the immediate accident scene as drivers navigated around the disabled vehicles.
The impact rippled across the entire north Houston freeway system. Drivers heading toward The Woodlands or toward Montgomery County faced significant delays, with many experiencing 30-minute slowdowns on I-45 North alone. The feeder roads running parallel to the interstate—particularly surface streets in the Greens area and along local connectors—quickly became clogged with diverted traffic. Commuters looking to bypass the corridor had limited options; FM 1960 and the surface roads feeding toward the eastside offered some relief, though those routes filled up fast as word spread about the closure.
This stretch of I-45 North has emerged as a persistent trouble spot in Harris County. Over the past three months, Exit 59 and its immediate vicinity have been the site of 51 major incidents among 84 total crashes recorded in the corridor. The area sits directly between downtown Houston and the steady stream of northbound traffic bound for The Woodlands and beyond, making it a natural choke point during peak hours and evening departures.
The northbound direction bore the brunt of the collision. By late evening, the status of the incident remained unclear—whether lanes had reopened or crews continued clearing the scene. Drivers heading through that section should expect delays and reduced capacity as cleanup operations continued. Given the severity of the crash, secondary effects on nearby interchanges and feeder roads likely persisted for several hours after the initial impact.
