Heading south, we’ve gone from Shannon tunnel in Russell County past the Guest River Gorge, past the old Miller Yard (it was quite a place in its day), to Townes tunnel in Scott County. It’s 1,098′ long. It’s at 36.851101, -82.436563. This view looks northerly, toward Miller Yard. This is an unusual horseshoe shaped tunnel, but the shape is related to the stress lines along the line of the tunnel. There was a train collision in this tunnel back in the day. It’s said you can still see the scars of the wreck inside the tunnel. I didn’t check, sorry. Starnes is next, then The Twins.
