The South Dakota Dept. of Transportation Bridge No. 48-244-204 is a historic bridge over the Little White River just west of White River, South Dakota. At in length, it is the longest concrete slab bridge in the state. It was built in 1934 to carry South Dakota Highway 44 across the river, but now carries a local road north of that road's current alignment. The bridge consists of eighteen concrete slabs, each in length, resting on a series of concrete piers, with wing-walled concrete abutments at both ends. Read more on Wikipedia
