Kinzua Viaduct by jw coulter

This gigapan shows the tornado damaged Kinzua Viaduct in northwestern Pennsylvania near Mt. Jewett. To the right is a swath of trees cut down by the tornado. Before the tornado hit it, the viaduct was the 4th largest railroad bridge in the U.S. at 301 feet high and it was 2052 feet long. On July 21, 2003 an F1 tornado stuck the bridge and knoced down 11 of its 21 towers. Rusted anchor bolts were to blame. The viaduct is a POI on the Sunday Drive App for iPhones. The viaduct is located in the Kinzua Viaduct State Park. This photo was taken September 2006 from the southern side of the viaduct.
