We used to walk across the Kinzua Bridge every year. Looking down thru the cracks always made me nervous, but it was still the highlight of our camping trips. Sorry we wont ever be able to do it again.
The 329-acre Kinzua Bridge State Park is in McKean County and features remnants of the 2,053-foot railroad bridge (viaduct) that was a National Engineering Landmark. A tornado has knocked down much of the bridge.
