I'm thinking two different locations. The one with abutments seems to have one overhead brace in the center. The one under the arch appears to have overhead braces at 1/3 span and 2/3 span.
The smaller one is closer to the water as well, and at the same level as the buildings.
The larger bridge and the arch as well as modern streetview suggest steeper terrain on either side of the water.
Luke (or anyone):
Does this look like two different bridges in the photos? The one with the stone arch in the foreground shows approaches to the bowstring span but I don't see them in the other photo, just abutments, no piers.
Same location, two bridges? Or two different locations/bridges? Or approaches that were later filled in?
Also how did we determine Morse as the builder? I am fascinated by Morse and if one of these photos really shows a Morse bowstring I would like to know which photo it is.
I'd say photo #1 is definitely a different location. The stream in photo #1 appears to be a good deal smaller than the Vermilion River, and the photo also depicts a good bit of flat ground beside the stream, whereas if you look at a topographical map of the Wakeman crossing there's 50-foot bluffs rising pretty much right from the river's edge.
