Located in Virginia's Shenandoah Valley, about midway between Roanoke and Lexington, Natural Bridge is 215 feet high, over 100 feet wide and about 50 feet thick. Natural Bridge was surveyed by George Washington and deeded to Thomas Jefferson from King George in 1774. The bridge was created perhaps 100 million years ago when Cedar Creek began flowing over the top of what is today the Natural Bridge. A waterfall was produced as the creek eroded the softer limestone rock. Gradually, the rock beneath the falls was also worn away, leaving behind the more resistant arch. Route 11 now runs across the top of Natural Bridge.
