Sometimes in transportation, our bridges cannot be saved (which can only be said after a Section 4(f) evaluation). Reasons often relate to safety or structural deficiency or loss of integrity, among other items. It’s a complex law and evaluation. Large bridges like the Champlain Bridge are rare projects; often bridge projects are much smaller.
Remember the Newfane Bridge?
Recently I drove through Newfane and saw its replacement. It was a historic bridge located within a historic district. To the public this means that a bridge replacement (if determined to be the only feasible and prudent alternative) will be a context sensitive solution; i.e., compatible with its surroundings.
New bridges will not look like the old bridges due to engineering designs, traffic safety, modern vehicles, modern materials, etc. How do you, as a historic preservationist, or a community member feel about historic bridge replacement?
