The 55-year-old driver had to be extricated from the vehicle. The driver was taken by ambulance to a nearby hospital. The victim's condition is unknown.
The driver told authorities he was looking at a map when he veered too far to the right and drove off the freeway. He said his car was going so fast that he went airborne down the embankment and cleared the water in Sims Bayou, landing in the mud on the south side of the bayou.
The car sustained heavy damage to its front.
