The Kinzua Bridge is a historic viaduct located in Kinzua Bridge State Park in Pennsylvania. Originally built in 1882, it was once the tallest railroad bridge in the world, standing at 301 feet high and spanning 2,053 feet across the Kinzua Creek.

Today, the bridge has been transformed into a scenic overlook and is part of a skywalk that allows visitors to experience stunning views of the surrounding landscape. The Kinzua Bridge State Park offers various recreational activities, including hiking and birdwatching, making it a popular destination for nature lovers.
