That makes sense. I might change the date to ca. 1910 in that case. This is a very rural area, so a very late changeover from pinned to riveted connections would not be a surprise.

This bridge has enormously massive members for its span length. As such, I am guessing its a very late pin-connected truss. ca. 1915 is not out of the question.

I have removed the build date of 1925 and replaced it with ca. 1900. This bridge is pin-connected, so it is almost certainly older than 1915.

I can't positively identify a builder. Coffey County did use the Canton Bridge Co. and this bridge has some features that I have seen on Canton Bridge Co. pony trusses. Thus, if I had to take a wild guess, the Canton Bridge Co. would be my first inclination. Compare to this one, which is a confirmed Canton Bridge Co product:

As a side note, P.E. Lane built some pony trusses in Coffey County as well. We should keep this in mind if any mystery bridges appear in the county.
