Kinzua Bridge, Mount Jewett, McKean County, Pennsylvania

State park
Nick Kovalchick, the owner of the salvage company, could not bear to dismantle the bridge. On seeing it for the first time he is supposed to have said "There will never be another bridge like this." Kovalchick worked with local groups who wanted to save the structure, and Pennsylvania Governor William Scranton signed a bill into law on August 12, 1963, to purchase the bridge and nearby land for $50,000 and create Kinzua Bridge State Park. The deed for the park's 316 acres (128 ha) was recorded on January 20, 1965, and the park was opened to the public in 1970.
An access road to the park was built in 1974, and new facilities there included a parking lot, drinking water and toilets, and installation of a fence on the bridge deck. There was an official ribbon cutting ceremony on July 5, 1975, for the park, which "was and is unique in the park system" since "its centerpiece is a man-made structure". The bridge was listed on the National Register of Historic Places on August 29, 1977, and was named to the National Register of Historic Civil Engineering Landmarks on June 26, 1982.
The Knox and Kane Railroad (KKRR) operated sightseeing trips from Kane through the Allegheny National Forest and over the Kinzua Bridge from 1987 until the bridge was closed in 2002. In 1988 it operated the longest steam train excursion in the United States, a 97-mile (156 km) round trip to the bridge from the village of Marienville in Forest County, with a stop in Kane. The New York Times described being on the bridge as "more akin to ballooning than railroading" and noted "You stare straight out with nothing between you and an immense sea of verdure a hundred yards (91 m) below." The railroad still operated excursions through the forest and stopped at the bridge's western approach until October 2004.
