(Highland Heights, KY) -- A 77 year old woman was hospitalized in critical condition after her car drove off of I-275, and landed, upside down, on the road below.

The first responders found the car on its top, and on fire, underneath the I-275 overpass, on Three Mile Road.  The driver was the only person inside, and was unconscious.  She was taken to St. Elizabeth in critical condition.

Investigators suspect the woman may have had a medical-related condition that caused her to lose control.
