When designated in the 1920's, South Dakota 73 only consisted of the segment from Faith (
U.S. Highway 212 ) to Lemmon (U.S. Highway 12 ). The remainder of the route was unnumbered.Around 1935, SD 73 was extended south from Faith, absorbing what had been a portion of
South Dakota Highway 24 to near Plainview, then southeast via a new route to Philip. From there, it was concurrent withU.S. Highway 16 to Kadoka then southward along what had beenSouth Dakota Highway 63 . It continued south to the Nebraska border south of Martin, after sharing an alignment withU.S. Highway 18 . Except for minor route straightening and a new concurrency withInterstate 90 , this route has not changed since.Around 1979, the northern terminus was extended east along U.S. 12 to Thunder Hawk, where it met up with a new road to link with ND 49.
