I would also like to add, that a bridge MAY NOT NOW BE ACROSS WATER, as the path of creeks and rivers changed in the last 100 years.
I like to think that this is the only "known" example of this type of truss. If a bridge is long abandoned, in a remote rural location, it won't show up on the NBI, and won't be visible from satellite photos. There "could" be another out there. Bowstring Truss bridges seem to be discovered all the time, relatively speaking. Remember the NBI only shows bridges on OPEN roads. And, and this is important, I have found inaccuracies in the "type" of bridge listed, and what is there in reality for a given location, so every location needs to be visited in person.
I think the same reason why we have only one Bollmann Truss, and if we're not careful, one Warren truss left, one Parker truss left, one Pennsylvania truss left, and...
why is this the only fink left in the nation. its horrible that this is the last remaining of this design left.
This bridge has been restored as a foot bridge at Camp Tuscazoar.
