Summary of Historic Significance
Bridge No. 92247 is a single-span, filled-spandrel, three-center-curve-intrados arch bridge, with an overall structure length of 53 feet, a clear span of 38 feet, with an out-out width of 53 feet. It is historically significant as an outstanding, virtually unaltered, extremely early example of a reinforced concrete arch bridge in Minnesota. Built in 1904, along with Bridge No. L-5853, it is the second oldest known extant reinforced concrete arch bridge with documented construction dates in Minnesota. This bridge is also significant for employing the patented Melan reinforcing system. Finally, it is significant as the work of noted Minneapolis bridge builder, William S. Hewett.
