It is possible that the bridge viewing down the axis is also the Jerome bridge. But even though it is the same truss style, it looked a bit longer and lower to the water to me. The reverse says: "Picnic at G_________ / Bridge". So it may say Gasconade, but I could only make the G match.
In the image looking at the side of the 3-span bridge there are 12 panels per truss span. The bridge marked 56 also has 12 panels per span, while the bridge known to be at the Gasconade River at Jerome has 10 panels per the posted truss span. So, this seems to be a different bridge. The 56 should give some idea on location, but I do not know the numbering scheme for the Frisco's bridges.
