Natural Bridge, small village, Rockbridge co., W Va., in the Shenandoah valley; founded 1774. Nearby is the famous Natural Bridge over the gorge of Cedar Creek. It is a limestone arch 215 ft (66 m) high with a span of 90 ft (27 m) and was once owned by Thomas Jefferson, who built a cabin there for visitors and kept a guest book. A public highway now crosses the bridge.

natural bridge

 or natural arch

Naturally created arch formation resembling a bridge. Most are erosion features that occur in sandstone or limestone. Some are formed by the collapse of part of a cavern roof. Others may be produced by entrenched rivers eroding through meander necks to form cutoffs. Still others are produced by exfoliation (separation of successive thin shells) and may be enlarged by wind erosion.
