Interesting information, Jason. Where in Winneshiek County was the Bridge moved to?
Growing up in Osage, we called our bridges South Bridge, Lime Kiln Road Bridge, and this one West bridge. The site of the Pierce bridge was called Old South Bridge.
There is also an interesting pontoon bridge just upstream from the site of Pierce Bridge. Sunny Brae Golf Course puts it out seasonally to reach an across-the-river green.
Here's a postcard image of West Bridge.
