If you come into the Gorge from the Railroad Grade Road side, this one’s easy to miss. The west portal of tunnel #5 is completely filled in and only the remains of the cut can be seen…look
This is the second tunnel on the line heading away from Johnson City up through Doe River Gorge. It’s centered at 36.265916, -82.171331.
My hiking buddy, clad in plastic against the cold, January rain, is standing in the western portal. This part of the line is intermittently active during the summer for excursions from the Ministry.
