South Dakota Highway 8 is one of only two single digit state highway numbers known to be used in South Dakota . It was a state route across north central and northwest South Dakota, generally following what is now South Dakota Highway 20 .


HISTORY

The first designation of this route, in 1926, was South Dakota Highway 18 . By the late 1920's, U.S. Highway 18 was established across southern South Dakota. The existence of two highway 18's was corrected around 1935, when the northern highway was redesignated as South Dakota 8. This number remained in use until the late 1960's, when SD 20 was extended west across the Missouri River , absorbing the SD 8 alignment.
