This great bridge, constructed by the Clinchfield Railroad, spans a gap between two ridges in the north Johnson City area. Johnson City has a history as a railroad town, once known as Johnson's Depot. Three railroads coexisted here: the Clinchfield, the East Tennessee and Western North Carolina ("Tweetsie"), and the Southern. This Boone's Creek Viaduct photo is on a span of the original Clinchfield Railroad. Now owned and operated by CSX, the intriguing mountain route of the original railroad, resplendent with tunnels and viaducts throughout its Appalachian route, is preserved and still in heavy use.
