This bridge is a large Deck Girder bridge over Lake Mitchell on the north side of Mitchell, South Dakota.
Originally built in 1911, this bridge was constructed to cross Firesteel Creek, which was later dammed to create Lake Mitchell. The initial span constructed was large 90-foot deck girder. In 1915, the south pier was rebuilt and by 1919, a 70-foot span would be moved here from the Whetstone River Bridge near Big Stone City, South Dakota. The final north span was added in 1927, and the history is largely unknown.
Constructed of three deck girder spans, the entire bridge is set onto concrete substructures. In addition, the bridge is built with a ballasted deck, common for Milwaukee Road bridges.
Overall, the bridge remains in good conditions.
The author has ranked this bridge as being locally significant, due to the common design.
