Kinzua Bridge State Park is located near Mount Jewett, PA. The park lies between U.S. Route 6 and Pennsylvania Route 59, along State Route 3011 just east of the Allegheny National Forest. The park contains 339 acres and features the remnants of a railroad bridge (viaduct). When this viaduct was built in 1881, it was the world’s highest and longest railroad bridge at 301 feet tall and 2053 feet long. On July 21, 2003 a tornado caused the center section of the Kinzua Bridge to collapse. In 2011, a new pedestrian walkway–the Kinzua Bridge Skywalk–was built. Visitors can walk 600 feet out on the remaining support towers, peer miles out into the Kinzua Gorge as well as peer down into the partial glass platform at the end of the walkway.
