This bridge never carried the River to River Road. The River to River Road crossed the Cedar at Moscow.

cool bridge, great stone piers. I would say a Pratt and I could be like 33% wrong or right. Who built it? Muscatine was the first real river town I did as a kid with a houseboat that looked like a trailer. The Mighty Mississippi....
According to the "Heubringer's Map & Guide for the River-to-River Road", it carried the Muscatine Branch of the River-to-River Road that went from Davenport to West Liberty via Muscatine: https://archive.org/stream/huebingersmapgui00hueb/huebingers...
