South Dakota Highway 54 was a short state route in southeast Gregory County, South Dakota.
History
South Dakota 54 was implemented around 1926 as part of the state highway network. Its western terminus was at South Dakota Highway 50 (present day U.S. Highway 18) at Bonesteel. It ran south and east through Fairfax to the Nebraska border. By 1935, it was pulled back to Fairfax, at the intersection with the new U.S. Highway 281.
Around 1953, due to the pending flooding of its old alignment, U.S. 18 was rerouted south onto this route, and SD 54 was limited to a 1-mile segment north of the border. This last segment was eliminated around 1960, when U.S. 281 was rerouted onto it.
