And what about the difference in substructures?

IF the photo was taken from the second truss bridge, you'd see overhead bracing.

Note the photographs distinct lack of overhead bracing.

How are you supposed to see the second truss bridge when the photo is taken from the deck of the second truss bridge? Photo location was almost under the rail bridge and on the opposite side from the book picture Anthony Dillon posted.

How do you know it's a heavier structure when the only other photo you have of the bridge is the very poor first photo that Anthony posted? This was much closer so of course it looks heaver.

It's a heavier bridge... period

There's supposed to be another truss bridge visible in the image, given the "Twin Bridges" nickname.

Said truss isn't visible in your image.

Ergo, your image cannot be from Danville.

Geographic place Danville (Ind.), Twin Bridges (Danville, Ind.)

Since they got the photo reversed I guess they could have made other mistakes but I am not convinced because you can't see the structure down to creek level in this photo.

It's definitely not this bridge based on substructure. It's probably another bridge on the same line in the area, as the caption on the IUB database reads "Bridge; Danville trip"

It, by context clues alone, can't be Danville, but it could be any bridge along the line headed into Indianapolis.

e.g. this substructure by the bridge in Avon: https://bridgehunter.com/photos/18/16/181695-L.jpg

It's still not the same bridge. That is a heavier bridge and the substructure is completely different.

After looking some more, I think the photo view point was from the west side on the road bridge looking up and east. By counting the vertical beams on the rail bridge it shows only about half of the rail bridge is in the picture.

Something is wrong with the photo, yes. I think the negative may be reversed. From the light it appears to be the north side of the bridge, looking east. The road bridge would be out of frame to the right. Also there is a hand written number in the corner of the photo which is backward and in the right corner. If you mirror the image it is correct in the left corner. It says 28 and something that looks like a J or maybe it's just a line.

The 2nd photo has been incorrectly identified by the library as being of this span. It is much heavier than the one replaced by the concrete arches in 1906. Also, the original bridge featured substantial wingwalls that are not seen in the 2nd pic. Lastly, the still extant road bridge sat directly underneath it and would have likely been seen in the photo.
