Western Portal of Kittatinny Tunnel, Pennsylvania Turnpike
Additional Details:
| The Turnpike, stretching 160 miles through the Appalachian Mountains between Harrisburg and Pittsburgh, the highway has been so designed as to make it virtually 'fool-proof'—no bad curves, no steep grades, no cross traffic. There are seven tunnels on the route at Laurel Hill, Allegheny, Ray's Hill, Sidling, Tuscarora, Kittatinny and Blue Mountain. |
