The uber-spooky Cumberland Gap Tunnel takes U.S. Route 25E underground, going beneath hills in the Cumberland Gap National Historical Park. The east portal of the tunnel is in Tennessee and the west portal is in Kentucky, making it one of only two American highway mountain tunnels that cross state lines. (The other is the East River Mountain Tunnel between Virginia and West Virginia.)
There's a lame and pointless Blair Witch-wannabe homemade hoax on YouTube that was supposedly "found in the woods" in this area. A comment someone left on the page is far more interesting than the video itself:
"It does not surprise me,if there are apparitions/ghosts,or residual paranormal activity in and around Cumberland Gap.
A lot of history and death,especially from the Am.Civil War,and car wrecks on Cumberland mountain.
Also my grandmother who would be 102, if living told me of a young blonde heaired blue eyed young man 18 yrs.old was killed on the old highway and rolled in a wool blanket and left there. Reminents of the old highway from the 1920's & 30's is still present on the mountain"
