The total length of this route is 432 miles (695 kilometers). HISTORY South Dakota 20 was implemented in 1929, but it was much shorter. The western terminus was at South Dakota Highway 45 northeast of Faulkton , and terminated in Watertown. Around 1944, the western terminus was moved further west, to U.S. Highway 83 . In the early 1950's, a short extension west was made again, to the town of Akaska . The eastern terminus was moved as well, to U.S. Highway 77 south of Milbank ; the extension to the Minnesota border occurred in 1954. In the late 1960's, the short stub between Akaska and U.S. 83 was redesignated as South Dakota Highway 20 Spur . SD 20 was extended northward along U.S. 83 to U.S. Highway 12 , then through Mobridge and across north central and northwest South Dakota, absorbing the alignment of what had been South Dakota Highway 8 .
