In Gilbertville, a village in the township of Hardwick, Massachusetts is this wonderful covered bridge that spans the WareRiver. It was closed to motor vehicle traffic a few years ago because some modern so-called engineers claimed that it was either unsafe or couldn’t be proved to be safe using modern computer tools. It is a shame, bridges that have lasted over 100 years, and show no damage whatsoever, are no longer considered safe. I would think that the survival of a bridge for that period of time demonstrates that it is safe, but what do I know. I’m only an electrical engineer, not a contractor who will make lots of money tearing this down and replacing it with a modern concrete and steel structure that gets attacked by road salt every winter.
