Ohio Inventory sheet says builder was the Marion Bridge Company. I have heard of neither the Mario or Marion Bridge Company.

That is fairly typical of what happened in that area in the 1980s. There were many historic through truss bridges replaced by modern pony truss bridges in those areas which at the time probably made sense on the more sparsely traveled roads.

Here is what the Historic Bridge Inventory has for this SFN Number:

John, the Street View shown here is for a different bridge: http://bridgehunter.com/oh/washington/8435014/

The 1905 bridge listed here I believe to be demolished and replaced with a welded pony truss. The old Mario Bridge Co. Bridge was a pinned thru truss.

I went down to the location today, wish I had my camera and located the bridge. The bridge is 3-4 miles north of the truss bridge in the street view. That area is loaded with 1980s era pony trusses like the one in the street view. This bridge has a wooden roadbed and is in ok shape except it needs painted. I am also kind of disappointed that there is a guardrail added. Overall this bridge is a good find because it has the built up beams etc you would expect with a 1905 bridge. It is a pratt pony truss. I have never been able to work the street view very well but this bridge is findable for somebody who is a little better versed.

Every now and then I need to ask a question. Does this look like any kind of 1905 era bridge? According to this picture it is a pony truss.
