A significant crash brought evening commute traffic to a crawl on SH-249 Tomball Parkway northbound at its intersection with the North Sam Houston Tollway on Tuesday, February 10, 2026, at 6:04 PM. The collision tied up a crucial corridor that feeds thousands of drivers northward toward The Woodlands and Spring during one of the day's heaviest traffic periods.
The timing couldn't be worse for northbound commuters trying to escape the Houston metro area during peak evening rush. Drivers faced substantial delays backing up along SH-249 as emergency crews worked the scene. Those heading north should consider diverting to US-290 or taking the North Sam Houston Tollway itself as an alternative route around the backup. For drivers already committed to the SH-249 corridor, exiting at Spring Stuebner Ranch Road or earlier turn-offs would have helped them avoid the gridlock altogether.
This stretch of SH-249 near the North Sam Houston Tollway intersection represents one of the busier gateways to the northern suburbs. The area sees constant traffic flow from both local commuters and through-traffic heading toward Conroe and beyond. Major developments along this corridor—including the continued growth in Spring and The Woodlands—have only intensified the volume on this already-taxed stretch of roadway.
The crash occurred in the northbound direction, creating significant spillover effects onto connecting roads throughout the Tomball and Spring area. Traffic monitoring data from TranStar indicated the incident was creating substantial delays for the evening peak. Drivers heading north on SH-249 or those merging from the North Sam Houston Tollway should have anticipated extended commute times until the scene was cleared and traffic patterns normalized.
