The 329-acre Kinzua Bridge State Park offers visitors a chance to walk the Tracks Across the Sky. Located in McKean County, this park is the home of the newly reinvented Kinzua Viaduct. The Viaduct, once known as the longest and tallest railroad structure at 2,054 feet long and 301 feet high, was partially destroyed by a tornado in 2003. In 2011, the engineering masterpiece was reinvented as a new pedestrian walkway where visitors can stroll 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. Picnicking and trail opportunities are available. The Kinzua Bridge Scenic Byway is a designated shared use hike/bike corridor.
