A major crash brought westbound traffic to a standstill on the North Sam Houston Tollway at Hollister Road just after midnight early Tuesday morning. The collision occurred at 12:19 AM, creating significant backups along one of the region's busiest outer loop corridors during the pre-dawn hours.
The incident tied up the westbound Sam Houston from the Hollister area for several hours, forcing early-morning commuters and late-night travelers to seek alternate routes. Drivers heading westbound on the toll road faced substantial delays as emergency crews worked the scene. Those looking to bypass the congestion had limited options at that hour—the feeder roads along the Sam Houston move slowly during peak gridlock, while diverting to I-45 North or heading south toward Beltway 8 would add considerable time to most trips.
This stretch of the North Sam Houston Tollway has long been a choke point for commuters traveling between Spring, The Woodlands, and areas north of Houston toward points west. The corridor sees heavy traffic both during typical morning and evening rush hours and increasingly throughout the day as the region expands northward. Hollister Road serves as a major access point to nearby residential developments and commercial areas, making this section of the tollway critical to the flow of traffic across north Harris County.
The westbound direction bore the brunt of the crash's impact, with significant delays extending for miles. Traffic began clearing by mid-morning as crews finished their investigation and removed debris from the roadway. Drivers traveling this stretch should anticipate residual slowdowns as crews completed their work and lanes reopened to normal flow.
