Here are several images taken from state highway maps over the years Some of these have been displayed on the individual route pages over the years, while others are new.
Old SD-30
SD-30 ran border-to-border in 1926, mainly as the original state number for current US-14. By the mid 1930's, the only segment left was from Belle Fourche to the Montana line; this was eliminated by 1940 with the extension of US-212.
US-212 Before Lake Oahe
Before the creation of Lake Oahe (under construction in 1953), the town of Cheyenne Agency had a population of 400, and Whitlocks Crossing had 150. Both were flooded after the lake was created. US-212 was rerouted along the road going to Forest City, before heading north across the lake. The old US-212 alignment now leads to the East Whitlock Lakeside Recreation Area.
Old SD-24A Map
Back in 1941, SD-24A was the new name given to the road going from Whitewood to Belle Fourche. Before 1950, the mainline SD-24 was rerouted onto this alignment. SD-24 was eliminated around 1960, when SD-34 was extended west from Pierre along the SD-24 alignment.
Sioux Falls in 1938
A 1938 map of Sioux Falls. None of these highway numbers exist in the city anymore, although the present end of SD-38 (at I-29) approaches the northwest corner of the city.
Sioux Falls in 1962
In 1962, much of the Interstate construction around Sioux Falls was complete, except for I-90 west of Cliff Ave. and I-29 north from SD-38.
