Crash Closes Westbound North Sam Houston Tollway at Bammel North Houston Road

A major crash blocked the westbound lanes of the North Sam Houston Tollway at Bammel North Houston Road early Saturday morning, shutting down traffic at 1:36 AM on April 11, 2026. The collision tied up one of the region's busiest tollway corridors during the overnight hours, forcing drivers heading toward the northwest side of Houston to seek alternate routes.

The westbound blockage created significant delays for anyone traveling toward The Woodlands, Spring, and points north and west of the Greater Houston area. Drivers were diverted to local roads including Bammel North Houston Road, Champion Forest Drive, and the frontage roads paralleling the tollway. Those heading to the northwest side had the option of routing through FM 1960 or taking the North Freeway to bypass the affected segment entirely, though both alternatives carried heavier-than-normal traffic as a result of the incident.

The North Sam Houston Tollway at Bammel North Houston Road has proven to be a persistent trouble spot. In the past 90 days alone, the location has been the site of seven major incidents—a troubling concentration that underscores the challenges this stretch presents to drivers. The area sits in a transitional zone where the tollway's high-speed traffic patterns meet busy intersections serving the rapidly developing northern suburbs. Heavy commercial vehicle traffic from distribution centers and industrial parks compounds the risks during all hours.

The incident occurred during the graveyard shift, a time when overnight drivers often travel at higher speeds on what they perceive to be open roadways. TranStar initially reported the crash as major, and the westbound direction remained affected through the early morning hours. Drivers heading west on the North Sam Houston Tollway should have expected extended travel times and were advised to allow additional time for their commutes until the roadway was fully reopened.
