A major motor vehicle incident shut down W Sam Houston Parkway South early Monday morning, June 15, at 1:43 AM, forcing crews to clear the roadway as light rain fell across Harris County.
The crash blocked lanes and tied up traffic during the pre-dawn hours. Responding officers cleared the scene, but the incident added to a troubling pattern on this freeway corridor.
