At the entrance to the Lehigh Gorge State Park just outside of Jim Thorpe, one can still see what's left of the impressive original CNJ track alignment from White Haven to Jim Thorpe - amazingly constructed in 1866 and known as the Turn Hole Tunnel. The line carried 2 tracks, but the tunnel was deemed unsafe, so a new line around the edge of the cliff right beside the parallel Lehigh Valley line was opened in 1912. The Turn Hole Tunnel and bridge wasn't abandoned until the 1950s. CLICK HERE for an impressive AB(2) photo from the top of this cliff that shows the 1912 CNJ arrangement (now a service road) and the adjacent LV trackage (now the RBMN).
