Laurel Hill Tunnel

Quemahoning Tunnel
(never used)

The Quemahoning Tunnel was constructed for use on the South Pennsylvania Railroad.
The tunnel is located in Somerset County.  The tunnel entrance is actually quite close to the current Pennsylvania Turnpike.  It is located near mile marker 106.3, so you won't need a compass or a GPS to find it. Although it was briefly used as a railroad tunnel, it was bypassed by the Turnpike Commission while building the turnpike.  The Quemahoning Tunnel was never used by automobiles.
