When I first posted this photo, I didn’t know where this bridge was located. However, since then, I and others, have figured out that this is the old Rochester Street bridge, before Rochester Street was realigned as Route 31. What is left of this street today is Moore Place.
The above photo of the school group is looking east. The old church steeple can be seen off to the right.
Bill Hecht sent around the bottom photo and I was able to place it as the same bridge. This was taken from the upstream or south side, looking downstream. I believe you can just see the old Erie Canal Aqueduct in the background. This view may have been taken from the first Erie Canal Aqueduct.
