Water reached up to the top of the SUV, trapping the woman, later identified as 71-year-old Dorthy Hoenig of Mesquite, inside.

As the water rose above her waist, she grabbed her soaking wet cell phone and called 911.

She says the water reached her neck before Dallas Firefighters were able to rescue her by pulling her out the driver’s side window.

Hoenig was taken to the hospital because of hypothermia concerns, but was later released.

The frontage road remains closed as water is still standing over the road.
