When first built in 1882, the Kinzua Viaduct was the highest and longest of its kind in the world. the last train to cross the bridge was in 2002. The bridge partially collapsed in a tornado in 2003. half the bridge still stands and was reinvented as the Kinzua Sky Walk, simply spectacular. The park offers a pavilion that can be rented for events, picnic areas, group tent camping and scenic overlooks.
