I'm guessing that when the sidewalks were added the substructure was changed from stone (Dry laid stone was very uncommon in Indiana) and the deck may have been upgraded. It likely had wooden stringers to begin with. The stone substructure looked pretty rough in the older photo and was likely from the earlier wooden bridge.

It's the same bridge... The walkways were added at a later date. The date given is only a circa (guestimate) date, but I did read that there was a wooden bridge (not sure if it was covered) that didn't last very long. It's definitely a tubular arch, and although the odds-makers would say it's a WIBCo product... A Rezner would not be out of the question. Come to think of it if it's a later version of the Rezner design it would have been manufactured by WIBCo. after their purchase of the Ohio Bridge Company.

Both of these photos came from out of an old book and the resolution is pretty lousy.

Oh - and the arch seen in the second photo _really_ does not look like it is the same bridge as the first photo.

There just isn't enough resolution... The original doesn't have great detail - but judging from the half-tone screening I found in the image it's all we've got. Unless someone can find the photo the newspaper used!

There are a lot of what appear to be lateral floor beams. More often than just at the verticals - which is odd. Having them rest on the lower chord would be a bad idea. Maybe they are just there to tie the deck together?

Regarding the top chord. I think it is round - or nearly round. The shadow line is so consistent at about half-way up that it can't be a flat sided beam. Maybe it's sort of a Phoenix type built up something.

I can see diagonals between verticals in a truss pattern. The top of some of the verticals look "forked", like maybe they are attached to both sides of the top chord.

I sure wish I could see more details!

The shadow line on the arch of the first picture makes it look like a Rezner but, I think 1880 is too late.

Thoughts?
