Kinzua Bridge State Park transforms engineering tragedy into triumph! The original 1882 Kinzua Viaduct—once the world’s highest and longest railroad structure—was partially destroyed by a 2003 tornado. Today, walk 600 feet out on the Kinzua Skywalk over the remaining towers, and peer through a glass platform to the gorge 225 feet below. The twisted remains of the collapsed section tell an unforgettable story of nature’s power.
