I have seen that construction on a few others bridges, but it is a rare find.

Here is a similar example:

I finally got some more of my pictures uploaded. Including the images of the lower end of the hip vertical rod. I have not seen a dual loop like this before.

Also, it doesn't seem to fit the crossing, and the bents supporting the bridge are a lot newer than the bridge. So I suspect it was moved here - but I sure don't know where it came from.

Only a few miles south of a major road, NE 2, but what a sweet bridge. It seems to be in decent shape too. It has iron or steel floor beams, but the stringers on the main span are timber! The deck is nailed to the stringers - and there were a few too many sticking up too high for me to risk my tires, so I didn't drive over it. The lattice railing is largely intact too. I have a bunch more photos to edit and upload...
