Yes Sir. Jerked the fifth wheel out there last year. Stopped to visit my son who's working in Cheyenne Wyoming with Schlumberger Oil Well Services.
Took a run down the Needles Highway in South Dakota. In the pic of the tunnel, at the far end of the tunnel is a sharp 80 degree bend in the road. Some Idiot the week before challenged himself to put a 33ft fifth wheel trailer and truck through the tunnel and then make the bend at the other end. Took the side off of the trailer and then couldn't make the bend. Had to call a tow truck to pick up what was left of the trailer and get it around the bend and back on the road. When you go through thre tunnel, you can see the paint transferrence on the walls.
Dimensions of the 3 tunnels on the Needles Highway
Hood Tunnel: 10 feet, 6 inches wide; 11 feet, 3 inches high
Needles Eye Tunnel: 8 feet, 4 inches wide; 12 feet high
Iron Creek Tunnel: 9 feet wide; 12 feet, 3 inches high
