I would expect to see rockers for the expansion end of a bridge from the late 1920's that looks like a DOT designed structure. Those rollers are unique, not like a traditional roller-nest but just two giant double-wheel rollers. I can't tell for sure how or if they are attached.
I also notice that just upstream is a nice round cut stone pier that survives from a lost swing-span. It appears to still have some of the rolling mechanism attached to it.
Yea! It's nice to see a Minnesota bridge not slated for demolition.
Unlike the Eisenhower bridge http://bridgehunter.com/mn/goodhue/9040/ that I went across recently and could see that ground work is beginning for the new bridge.
Inspected this bridge 6/7/17. Bridge was completely repainted to a battleship gray color in 2016. Looks good!
Interesting expansion rollers.
This is during the spring thaw/flood of 2006. The water is about 25-30 feet above normal levels at this point.

Tony: there is a specific reason for these bearings. Someone did a presentation on this bridge, I think it might have been at an SIA Conference. But a brief overview is here: https://www.dot.state.mn.us/historicbridges/4700.html
