. It mostly followed the path of what would become
US 77, which had been designated by 1931. The highway then went north from Milbank, west to Wilmont, and north to Sisseton. It then went north to Hammer along US 81. From there, it went west to Claire City, and then north to meet
ND 18. By 1932, the only portion of this highway that remained was from US 12 to the North Dakota state line.
In the early 1950s, SD 15 was rerouted so its southern terminus was at US 12/US 77 in Milbank. It then went north to Hartford Beach, and then west through Wilmot to US 81, before heading north again; the old alignment from US 12 to Wilmot was redesignated as SD 15A. In 1976, the northern terminus was truncated to US 81; the segments of SD 15 near the North Dakota state line became SD 106 and part of a realigned SD 25. After US 77 was decommissioned in the state in the early 1980s, SD 15 then extended along its former alignment south from Milbank, to the present southern terminus.
