Police tell us the woman in her 20s was driving westbound on the Katy Freeway near Greenhouse when she may have hit an 18-wheeler. That contact sent her car out of control and into a concrete barrier.
She was wearing a seat belt, but the impact tore that seat belt and she was ejected onto the freeway.
She was taken by Life Flight to Memorial Hermann Hospital to be treated for a broken leg and chest injuries.
The freeway was shut down for more than two hours while police investigated.
