Location is a guess. Miriam Wood's book describes it as being "about two miles south southwest of Defiance".
Likely 1883 is the date then when the Whipple truss was erected.
Art, I'll try my very best 😉
Melissa,
Can you work your magic on this one?

Paul,
Nice find! Now we're up to four CBW inverted bowstrings!
I'm curious what we'll learn. My suspicion is that it was replaced/lost no later than 1913.
A combination truss (wood compression members and iron tension members) is certainly possible although an odd choice if the 1875 date holds. David Morrison was very flexible with material in his design offerings, not to mention the designs. However, he first started using it in 1859 and it is my understanding Germantown https://bridgehunter.com/oh/montgomery/germantown/ was actually made in 1865 (in spite of the big 1870 labels all over it).
Dayton's Main Street Bridge https://bridgehunter.com/oh/montgomery/bh75218/ and South Bend's LaSalle Avenue Bridge https://bridgehunter.com/in/st-joseph/lasalle-avenue/ both 1870 - 1871 were all iron.
Unfortunately, Miriam Wood passed from Alzheimer's in May (2021). https://www.newcomercolumbus.com/Obituary/199495/Miriam-Wood... I would love to know what she used as source material.

Here's one you might find interesting, Art!
I tried finding a photo but no success yet. Judging from that my guess is that it did NOT survive until 1974, when the current Harding Road Bridge was built. No facts yet though....
Agree Paul but would love to find documentation
