Built in the 1830s, the Staple Bend Tunnel was the first railroad tunnel, and the third tunnel of any kind, in the United States. Located about four miles east of Johnstown, PA, the tunnel is part of the Allegheny Portage Railroad National Historic Site, which operated between 1834 and 1852 and played a critical role in opening the interior of the United States to trade and settlement.
