This pair of bridges was a small reminder that Minnesota Highway 100 was originally one of the first freeways in the nation.
Built in 1937 to cross the new highway, the bridge featured a pair of stylish Through Girder spans on concrete substructures.
However, a rebuilding program eliminated the remainder of historic bridges on highway 100 between 2014 and 2015.
The south span was demolished in 2014, and the active railroad track shifted to the north span. The north span was removed in 2015 after the new railroad bridge completed.

The author has ranked the bridges as being moderately significant, due to the unique history of the structure.
