When first implemented in 1926, the western terminus was at
South Dakota Highway 45 near Gann Valley. In the 1940's and early 1950's, a road was gradually built from Pierre to SD 45 via Fort Thompson, and SD 34 was extended west along it upon its completion. A further extension westward occurred in 1961, when SD 34 absorbed the alignment ofSouth Dakota Highway 24 .In the late 1960's, a portion of SD 34 (along with
U.S. Highway 14 ) was upgraded as part of the construction ofInterstate 90 . The segment between Whitewood and Sturgis (exits 23 and 30) remains signed with I-90 and U.S. 14.A 10 mile segment of SD 34 in Sanborn County has been upgraded to 4 lanes. This is part of a 4-lane route from Huron to Mitchell via
South Dakota Highway 37 .Legal Definition
