Nada Tunnel is a 900-foot tunnel that carries KY Route 77 under Tunnel Ridge at Red River Gorge Geological Area in Kentucky. It was originally constructed for the Big Woods, Red River & Lombard Railroad in 1910 to access the virgin forests of the Red River valley.
The tunnel, measuring 13-feet-side and 12-feet high, was constructed between December 1910 and September 1911. 1 A 25-ton and a 35-ton Climax locomotive were used to haul logs from the Red River valley through the tunnel to a sawmill 15 miles west in Clay City. The first load of logs, however, became jammed in the tunnel and had to be dynamited loose. The Nada Tunnel was then enlarged to accommodate larger loads.
