History and significance

The Kern Bridge was a single-span, wrought-iron, bowstring arch through truss resting on limestone abutments. The bridge was located in in the southeast corner of South Bend Township in Blue Earth County. The bridge was constructed by John Mahowald and the Wrought Iron Bridge Company in 1873. The bridge was significant as the only example of a bowstring through truss bridge in Minnesota and for its exceptional span length.

The bridge was removed from this site, dismantled, and stored for relocation in winter 2020.
