Staple Bend Tunnel Trail Open, Staple Bend Tunnel Close
The Staple Bend Tunnel is closed until further notice, but the Staple Bend Tunnel trail is open for use. Again, the tunnel, NOT THE TRAIL, is closed.
Please be aware that part of the public area loop has been closed until further notice as the park starts preparatory efforts for this summer's paving project on the Picnic Area Road.
Natural Features & Ecosystems
The mountainous terrain of the Allegheny Mountain section of the Appalachian Plateau posed a problem to the Pennsylvania Mainline Canal, leading to the creation and use of incline planes that came to be known as the Allegheny Portage Railroad. The terrain-influenced form of transit, once novel and innovative for its time, is the backbone of the park’s history.
Did You Know?
John A. Roebling of Brooklyn Bridge fame got his business start with the Allegheny Portage Railroad. His wire rope was used on each of the 10 inclines. It also was used for suspension aquaducts on the Mainline Canal.
