Houston Police Department units responded to the scene near 6701 W Sam Houston Parkway South, where the crash resulted in significant delays for the handful of drivers on the road during the overnight hours.
The incident occurred during typically light traffic conditions, but the severity of the collision still managed to create backup extending across multiple lanes.
