Major Crash Snarls North Sam Houston Tollway Westbound at Ella Boul...

A significant crash brought westbound traffic to a crawl on the North Sam Houston Tollway at Ella Boulevard on Monday, February 23, 2026, at 7:41 AM, according to TranStar.

The accident struck during peak commute hours when thousands of drivers funnel westbound toward the Energy Corridor and downtown Houston. Expect delays extending well into mid-morning as crews work to clear the roadway. Drivers heading west on the Sam Houston should consider taking I-45 north toward The Woodlands or routing through local roads via Ella Boulevard itself to bypass the toll road entirely. Those already committed to the tollway can expect backup extending several miles—likely back toward the Greens Road area and beyond.

This stretch of the North Sam Houston has long been a bottleneck during morning hours, particularly when incidents occur. The Ella Boulevard interchange serves as a major junction feeding traffic from the north side neighborhoods and connecting commuters headed toward Spring and The Woodlands. The tollway at this point carries some of the busiest traffic volumes in Harris County, with Ella serving as one of the primary north-south arterials feeding into the system.

The westbound direction bore the brunt of this incident. As of late morning, the status remained unclear whether the roadway had been fully cleared, though major crashes at this location typically tie up traffic for at least two to three hours. Drivers should remain alert for emergency personnel and potential debris scattered across the lanes, as secondary accidents frequently occur in these congested conditions.

A major crash at this interchange could easily add 30-45 minutes to typical commute times for the westbound corridor. Spillover traffic was likely backing into local roads and alternative routes, with congestion trickling onto feeder roads and creating cascading delays across the northern Harris County freeway network.
