The Kinzua Bridge or the Kinzua Viaduct was a railroad trestle that spanned Kinzua Creek in McKean County in the U.S. state of Pennsylvania. The bridge was 301 feet (92 m) tall and 2,052 feet (625 m) long. Most of its structure collapsed during a tornado in 2003.
The bridge was originally built from wrought iron in 1882 and was billed as the "Eighth Wonder of the World", holding the record as the tallest railroad bridge in the world for two years
The bridge was designed by the engineer Octave Chanute and was built by the Phoenix Iron Works in Pennsylvania
