In Toledo, Ohio, a sinkhole opened up at a busy intersection Wednesday, sending a woman and her car plummeting beneath the earth.

Pamela Knox was driving not far from her home when the ground split open. Knox told the Toledo Blade that the road "caved in" underneath her Chevy Malibu. The sink hole is reportedly 20 feet long and at least 10 feet deep.

"My car started falling and rolling over and over until it came to a stop, " she said, adding that it landed on its front wheels and that water from a burst pipe started flowing into the back seat.

"I didn't know what was going to happen. I thought I was going to die," Knox told The Blade. "It was very scary. I didn't want to keep looking at [the water] because it made it worse. I stayed face-forward, but it was filling up that back seat."

Knox, a 60-year-old elementary school principle, was taken to a hospital before being released. Her car had to be removed from the sinkhole with a crane.

City officials believe the sinkhole was caused by the collapsing of combined sanitary and sewer systems. The Blade reported that the collapsed sewer system was built in 1891.

Toledo Mayor Mike Bell speculated that recent heavy rains may have also contributed to the road collapsing, the Blade reported.
