I'm fairly certain this bridge and the bridges at Janesville and Central City were built using parts from the original iteration of the swing bridge at Dubuque.

The bridge almost certainly reused from another location. The original endpost baes would have been cast iron. To my eye, the enposts look like Keystone Columns.

I agree with Tony. Looks like a mid 1870s structure that could have served as part of a much larger crossing at one point.

I think this is actually a railroad bridge...and an extremely early (ca.1870's) one at that.

The built-up endpost bases are very unusual.
