Located in Scott County VA, where the Clinch River makes a wide bend, these two tunnels bypass it by cutting through two close ridges. The North Twin (308′) is 71.26 miles south of Elkhorn City (quickly vanishing in the distance, well over the horizon, lost in Kentucky). The South Twin is just a few feet beyond the North. If you were standing between them, you’d be at 36.709679, -82.646909 and an elevation of 1343′. South Twin is just 236′, a mere slip of a tunnel. The first picture is the south portal of South Twin, looking north to the North Twin. The second picture is the north portal of North Twin, looking south to the north portal of South Twin. They’re both dated 1912.
