Summary of Historic Significance
Bridge No. L-4770 is a single-span, stone-arch bridge that carries Township Road 213 over Mahoney Creek. The bridge is historically significant for the engineering embodied in its design and construction. The bridge displays the essential features of a standard stone-arch design that appears to have been developed by the Minnesota State Highway Commission during the second decade of the 20th century for use in rural areas of southeastern Minnesota. Bridge No. L-4770 is the only surviving example of the design in Fillmore County and one of the few unaltered examples in the state.
