Rockbridge's natural arch or bridge is more than 100 feet long and 10 to 20 feet wide, and gracefully arches 50 feet across a ravine. It is considered the largest natural bridge in Ohio. Ohio is a land of diverse geological features. Among the most unusual and spectacular formations are its natural rock bridges. Ohio has at least 12 such bridges. These bridges (or stone arches) have been found primarily in the area characterized by massive sandstone outcroppings in south central and eastern Ohio.
