Summary of Historic Significance
The Intercity Bridge is a reinforced concrete, open-spandrel, two-rib, continuous-arch bridge. Each of the three main arches has two five-centered ribs with a 300-foot span. The main spans are flanked by single arch spans of 139 feet each. The bridge is historically significant as one of the largest reinforced concrete bridges ever built in Minnesota and is a significant engineering accomplishment. The bridge is also historically significant as the major work of Norwegian-American engineer Martin Sigvart Grytbak. Although the deck was rebuilt and widened in 1972-1973, the bridge retains full engineering integrity as a monumental, continuous-arch bridge.
