SAN ANTONIO -

An 18-wheeler ended up on top of a car following a crash Monday afternoon at Highway 151 and Pinn Road.

Details are slowly coming in, but we do know the crash happened on the eastbound lanes of Highway 151.

Access roads on the eastbound and westbound lanes of Highway 151 were closed, but have since reopened.

There is no immediate word on casualties.

A strong odor of fuel prompted a hazardous materials crew to be dispatched to the scene.
