Possibly replaced in 1973, but I suspect earlier than that. I have gathered this bridge is this location because of the writing on the postcard.

Childs or Long pony truss is a real stretch. I have seen a few very early Pratt ponies with vertical endposts that used doubled diagonal members and counters in every panel.

No evidence that this has any correlation to Morrison or Columbia BW.

Upper cord cast iron?

Same builder?: http://bridgehunter.com/pa/franklin/paxton-run/

Interesting bridge. This strikes me as a Childs or Long truss which are normally associated with wooden covered structures. The rolled members and connections strike me as a Morrison/CBW structure. He had built wooden trusses however most known early Morrison designs involve bowstring or inverted bowstring designs.

Anyone have any thoughts?

Also, I have doubts about its location.
