Kinzua Bridge, Mount Jewett, McKean County, Pennsylvania

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.
As of 2009, Kinzua Bridge State Park is a 329-acre (133 ha) Pennsylvania state park surrounding the bridge and the Kinzua Valley. The park is located off of U.S. Route 6 north of Mount Jewett in Hamlin and Keating Townships. A scenic overlook within the park allows views of the fallen bridge and of the valley, and is also a prime location to view the fall foliage during the first two weeks of October. The park has a shaded picnic area with a centrally located modern restroom. Prior to the bridge's collapse, visitors were allowed on or under the bridge and hiking was allowed in the valley around the bridge. In September 2002 the bridge was closed even to pedestrian traffic. About 100 acres (40 ha) of Kinzua Bridge State Park are open to hunting. Common game species are turkey, bear and deer.
