Natural Bridge (Virginia) For the nearby unincorporated community of the same name, see Natural Bridge, Virginia. Natural Bridge is a geological formation in Rockbridge County, Virginia, comprising a 215-foot-high (66 m) natural arch with a span of 90 feet (27 m). It is situated within a gorge carved from the surrounding mountainous limestone terrain by Cedar Creek, a small tributary of the James River.
Established in 1926. The sandstone arch that is called Natural Bridge has stood for millenniums. The arch is 78 feet long, 65 feet high, 12 feet thick and 20 feet wide. Some geologists believe that the stunning natural sandstone arch is at least a million years old. There are other natural archways in the area, but none have gained the prominence of Natural Bridge.
