Drivers are stuck in a major traffic jam near Highway 90 outbound at Cravens, just south of Beltway 8.
HPD said in a tweet Friday afternoon that southwest side officers have been sent to clear traffic.
A pole was toppled by the crashed 18-wheeler and debris can be seen scattered along the roadway.
The big rig has extensive damage from the front to the rear of the vehicle.
We do not know the circumstances which led up to the crash.
