Good observations on the bridge clark.I would have to agree with you about the bridge possibly being moved to the present location.Doesn't look like it was put there originally when built and there is no builders plaque,is there?If anyone does know,maybe they can settle this mystery.

None of the old maps of this area show a road here. The abutments don't look brand new so we have to guess that some time in the fairly recent past this was relocated here. There are a couple of nearby locations where newer bridges suggest an older bridge was removed. I'm sure someone nearby knows the story. It's an interesting design that makes me wonder if there are any others nearby.

I have to agree with you Elliott about farmers buying these bridges and putting them there for farm equipment.I looked on the map and saw the road as you call it deadend at the field.

I see old bridges set up near fields like this all the time. My guess would be that farmers buy these bridges when they are being replaced and place them as crossings for farm equipment. I mean, I cant imagine an old road alignment ever going through there. Thoughts?

Maybe a tied arch rather then a bowstring?

A very cool and unique find Steve!

It could easily classified as an arch over a truss. Are those true verticals or just used to support the floor beams? The lack of any other members would lead me to lean toward it being an arch. Might be a good debate topic on BH!

As far as manufacture goes... It doesn't look "Homegrown", and I would believe it to be from a bridge company. I've not seen anything else quite like it.
