With few exceptions, that is pretty much the way Putnam County has been toward it's historic spans. They close, and sometimes quietly remove, their metal through trusses. They avoid federal funding to skirt preservation guidelines in replacing their metal pony trusses. Even their covered spans are not National Register listed which allows for questionable repairs which are not always in-kind.

They still have a really nice collection of wooden, metal and concrete spans. It would be nice to see them adopt a plan to take care of them.

The skew of this bridge along with a noticeable grade create a complex and bizarre structure that is quite unique. The county highway supervisor said "There's nothing in the design of that bridge that merits it being historical." I don't know what his training or experience with historic bridges consist of, but my seven years of obsessive involvement in historic bridges leads me to strongly disagree with his statement. I have not seen many concrete arch bridges with both a noteworthy grade and a heavy skew.
