History and significance
Bridge 3398, constructed in 1920 by the Minneapolis Bridge Company, carries Old Highway 12 (former County Road 79) over the Minnesota River in Ortonville, Big Stone County. The road has been converted to a pedestrian path. The reinforced-concrete, open-spandrel, single-span rainbow arch bridge was designed by the Marsh Engineering Company of Des Moines, Iowa, and features Classical Revival-inspired design aesthetics, including the integral, open balustrade railing and decorative endposts. Bridge 3398 is significant as an example of the work of James Marsh and his concrete rainbow arch design patent.
