I have been told it is still there to see. I have never been there but it is on my short list of places to visit with the old cars. Here is info from a website on the bridge:
More info on the Kinzua bridge.
The Kinzua Bridge, near Kane,
Pennsylvania, was the highest bridge in
the world when it was first built in 1882.
Its remnants today serve as a memorial
of a time when the U.S. was going
through the Industrial Revolution.
Rust and a tornado on July 21, 2003
destroyed most of it and bridge debris
litters the forest floor. The bridge was 301 feet (92 m) tall and 2,052 feet (625 m) long prior to its collapse in 2003. The bridge was originally built from 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. In 1900 the bridge was dismantled and simultaneously rebuilt out of steel to allow it to accommodate heavier trains. It stayed in commercial service until 1959 and was sold to the Government of Pennsylvania in 1963, becoming the centerpiece of a state park. Restoration of the bridge began in 2002, but before it was finished, a tornado struck the bridge in 2003 causing a large portion of the bridge to collapse. Corroded anchor bolts holding the bridge to its foundations failed, contributing to the collapse.
