Natural Bridge

Natural Bridge in Rockbridge County, Virginia is a geological formation in which Cedar Creek (a small tributary of the James River) has carved out a gorge in the mountainous limestone terrain, forming an arch 215 ft (66 m) high with a span of 90 ft (27 m). It consists of horizontal limestone strata, and is the remains of the roof of a cave or tunnel through which the creek once flowed. It is crossed by a public road, U.S. Highway 11. There are fences on either side of the highway, blocking the view from the top of the bridge. Natural Bridge has been designated a Virginia Historical Landmark and a National Historical Landmark.
