The Kinzua Viaduct was once the largest and highest railway viaduct in the world serving the New York, Lake Erie and Western Railroad. It began in 1881 and was rebuilt in 1900 to carry heavier loads. it was primarily used to ship coal, lumber and oil. Service on the Kinzua Viaduct was discontinued in 1959. In 2003, an F-1 tornado partially destroyed the structure. This past year its walkways were reconstructed. It is located right near Route 219 and US 6 in Pennsylvania.
