The building of the original structure of the Kinzua Viaduct began in 1881 and was nearly completed by 1882. The bridge was built with tough iron as it stood 300 feet high, more than 2,000 feet long and weighed over 3 billion pounds.
With the heavy cargo in trains, the entire structure of the bridge had to be torn down. The new steel structure was built in about 100 days as it weighed twice as much as the original. In 1959, all the freight traffic was discontinued as the bridge became an official state park in 1970.
In 1987, the bridge began operating with the Knox& Kane Railroad from Kane, Pennsylvania. The operation continued until 2002 when the state decided to stop the course to inspect the bridge where sections were rusted through, making it completely hazardous.
In February 2003, Kinzua Viaduct began its repair, when suddenly, an F1 tornado struck Kinzua Viaduct on July of 2003. Over eleven out of twenty towers were torn from the size of their concrete bases and scattered around the surrounding area.
The state of Pennsylvania had the opportunity to rebuild the national structure but rather decided to reopen the bridge as a pedestrian walkway. The reconstruction of the structure may have cost at least 50 million to build a train bridge in the middle of nowhere.
Currently, you can visit the visitor center and the skywalk as the walkway is a 225-foot observation deck with a glass floor. The Kinzua Bridge is considered as the tallest railroad bridge in the world with its original construction in 1882. Before it collapsed, it was ranked as the 4th tallest bridge in the entire United States.
There is no visitation fee to check out the park or Sky Walk. You and your family can enjoy a picnic or hike through the endless trails along the area.
