A major crash brought traffic to a standstill on the East Sam Houston Tollway northbound at Tidwell on Thursday, February 19, 2026, at 3:54 PM, impacting one of the busiest corridors during the afternoon commute. The incident occurred during peak travel hours when thousands of drivers typically funnel through this stretch heading toward the Pasadena and Baytown areas.
Drivers heading north on the Sam Houston encountered significant delays as emergency responders worked the scene. With the northbound lanes affected during the 3:54 PM crash, backup stretched for miles in both directions as rubbernecking compounded the gridlock. Those looking to avoid the backup should consider taking the feeder roads parallel to the tollway or rerouting via the Gulf Freeway northbound as an alternative to reach the northeast sections of Harris County. Local surface streets in the Greens Bayou area would also provide a workaround, though expect secondary congestion on those routes as well.
The East Sam Houston Tollway at Tidwell sits in a critical traffic corridor that handles daily commute traffic from Southeast Houston heading toward the petrochemical plants and refineries along the Ship Channel. This particular stretch, running between the Hobby area and Pasadena, sees consistent heavy volume throughout the day. The Tidwell intersection area has long served as a major junction point where industrial traffic merges with commuter flows, making crashes here particularly disruptive to the overall regional traffic network.
As of the report time, the northbound lanes remained impacted by the major crash. The incident's severity meant that even after responders cleared the immediate scene, residual traffic would likely persist through the evening commute. Drivers heading through the area should monitor real-time traffic updates via TranStar or their navigation apps for current conditions, as clearing a major accident on the Sam Houston Tollway typically takes considerable time given the volume of vehicles involved and the infrastructure of the roadway itself.
