It was built by the Civilian Conservation Corps, who is responsible for the original Oconaluftee Visitor Center and the tower at Mount Cammerer. The reasoning behind the tunnel under Clingmans Dome Road is unclear, but there are a few possibilities. One is that Clingmans Dome Road is elevated above the Appalachian Trail, so switchbacks or stairs would have been needed to go up or down the road crossing. Another is that the tunnel was designed for equestrian use to eliminate conflicts between horses and vehicles.
