Laurel_Hill_Tunnel--Kyle_Eugene_Petty

Laurel Hill Tunnel is a 4,541-foot-long (1,384 m) tunnel on the Pennsylvania Turnpike that was bypassed and abandoned in 1964. It is bored through Laurel Ridge, spanning the border of Westmoreland and Somerset counties. Its western portal may be seen from the eastbound side of the Turnpike at milepost 99.3.
The tunnel was built for the never-completed South Pennsylvania Railroad, as were two other tunnels to its east—Sideling Hill and Rays Hill—that were similarly on the original Turnpike and abandoned after being bypassed.
