Unfortunately, I think that the manufacturers of these MOB's (or Modern Ugly's as I like to call them) like to tout them as being "just as good" as the historic spans they replace. And while maybe they are stronger, in no shape or form can they match the integrity of those iconic structures that are lost. Weather the powers that be 50 or so years from now deem these modern trusses as historic remains to be seen. But for now I can't understand the logic that is used (Not Used!) in most of these situations. While I have no problem with these modern spans being used in new applications, I will always abhor them replacing an historic bridge that can be rehabilitated.
Robert,
Something must have changed in the last few years with NY's approach to historic bridges, as my last couple of jaunts through upstate NY (Clinton/Essex counties) have shown a large number of historic bridges lost, either being replaced by modern welded pony trusses or in the most recent ones just UCEB's. Even some of the more modern 1930's have been subject to replacement in the last few years, despite still being in relatively good condition.
The loss of this bridge is a surprise. If you visit Nathan's page (see link), this bridge looked like it had a relatively new coat of paint. Plus, it was in New York, a state which from what I can tell has an exceptionally good track record for preservation.
Stopped by this bridge today and talked to the crew. Truss was cut up and went to Ben Weitzman and Son Binghampton NY. not sure if shredded yet but if anyone was interested in parts and pieces could contact Weitzmans.
