You have a valid point Nathan... I must channel my inner-cynic and try to be more rational about these things! ;-)

Tony, your understanding of reality is flawed. Preservation of historic metal truss bridges is not physically possible in some places... The laws of physics that apply in Indiana do not apply in some places such as Missouri and Pennsylvania. Engineers in these states make statements about feasibility of reuse and preservation of historic metal truss bridges that are in total contradiction to what has occurred in states like Indiana and Michigan. One can only conclude from such statements that the laws of physics differ from state to state.

I compare it to a crime when all of these beautiful and timeless structures are sitting around just waiting to be brought back to life! If using historic bridges for trails could become the norm, then more people would be able to appreciate the history of them...especially if they are properly signed!

This is why I cringe every time I am on a trail and I encounter a MOB. Using a MOB instead of a salvaged historic truss bridge further inhibits our ability as Bridgehunters to explain the historical significance of truss bridges and what they can tell us about American engineering.

They have a perfect little park right downstream in Seneca. Looks like they have a couple of nondescript pedestrian spans, but how much better would it have looked with this beautiful pony truss instead!

This one has been replaced. Unless it has been relocated, it is lost.

Andrea Wilkins sent these photos of this Canton Bridge Company to me (www.historicbridges.org) of this half-hip Pratt pony truss with pinned connections and an unknown construction date. The plaque is mounted on top of the end post and has no date, but does credit the Canton Bridge Company. This bridge is slated for demolition and replacement. The structure is in a condition that would allow for an easy restoration. This bridge does not deserve to be demolished!
