About 20 mi south of Lexington, this impressive limestone arch (which supports Route 11) has been gradually carved out by Cedar Creek, which rushes through 215 feet below. The Monacan Native American tribe called it the Bridge of God. Surveying the structure for Lord Halifax, George Washington carved his own initials in the stone; Thomas Jefferson bought it (and more than 150 surrounding acres) from King George III. The after-dark sound-and-light show may be overkill, but viewing and walking under the bridge itself and along the wooded pathway beyond are worth the price of admission. On the property are dizzying caverns that descend 34 stories, a wax museum, a toy museum, and an 18th-century village constructed by the Monacan Indian Nation.
