Clinchfield Holston Tunnel
Photo taken by Calvin Sneed in December 2011
Of all the tunnels on the original 277-mile route of the Clinchfield Railroad, this tunnel is the shortest, at 154 feet. The unlined south portal immediately opens up to a deck truss trestle that is built right up to the tunnel entrance. The bridge is the only crossing of the Holston River, South Fork.
