Well, that is too bad. Overall, Geary County has done a great job of preserving historic bridges. I would have liked to have seen this one.
This one has recently been replaced. Looks like a piece of the old pony decking sitting off to the side of the new bridge.
The shadows appear to indicate a 3-panel half-hip Pratt pony, very similar to this one in Washington County, Wisconsin:
Kind of a Queen post shadow to it......
This one has been on my bucket list for a while. Like many spans with a Kansas Default Date of 1910, it may be pre-1900. This bridge does not appear in the KHRI. That being said, Google Maps clearly indicates a pony truss.
For whatever it is worth, P.E. Lane apparently built a 50 foot span somewhere in Geary (Davis) County. Whether or not it is this bridge, is pure speculation at best.
