8th wonder of the world

We stopped to see what once was called the 8th wonder of the world, in he Allegany National Forest, is the most amazing Kinzua Bridge. 

This bridge was built in 1882, it was truly an engineering masterpiece. It once soared 301 feet high and 2,053 feet across and was at one time he highest and longest railroad bridge in the world.  The engineer, who built it, Octave Chanute, also helped the Wright Brothers fly! I would have loved to have met that man! 125 men completed that bridge in just 94 days, that’s crazy!

It was an engineering breakthrough; they designed tall wrought iron columns able to resist vibration and buckling.

1900  they had the trains became heavier, so they had to erected with 6.7 million pounds of steel. 

Then in 2003, in 30 seconds, mother nature sent through a tornado. She tore  through the forest, ripped out 100s of trees and 11 of the bridges 20 towers were lifted and thrown onto the valley floor.

Now the bridge is a Sky Walk, they even added a window floor where it ends.
We were very impressed.
