BH Photo #369334
I found a report that two 110' iron through trusses were built on the Little Rock & Ft. Smith Division of the Missouri Pacific in 1891/1892. I have not seen any other 110' trusses listed, meaning this could possibly be one of those two trusses. While not confirmed, it may point us in the right direction at least.
Made it to this one with my buddy Wayne on Saturday. Very much looking forward to the nature trail opening up through this, neat old bridge
Panoramio photograph of this bridge. The photograph is "All Rights Reserved", so I am just going to post a link.
The bridge is a 5-panel Pratt truss. If I had to guess a construction date, I would say ca. 1885-1895. It looks too heavy to be earlier than that, but it does not have the standardized appearance of a post-1900 bridge either.
Bing Maps has some new aerial imagery for the area. This one looks very lightweight for a railroad bridge. Hopefully the Landon Trail folks will re-use it and not replace it with a MOB.
