South Dakota Dept. of Transportation Bridge No. 49-095-190 is a historic bridge in rural Miner County, South Dakota. It carries a local road over Rock Creek, about south and west of Howard. Built in 1917, it is the longest pre-1920 concrete slab bridge in the state. Bridges from this time predate the standardization in the methods and use of concrete in bridge construction, and are relatively rare. The bridge consists of a single span in length, with a solid concrete parapet as a railing. The concrete is suffering from spalling. Read more on Wikipedia
