. By 1936, SD 45 was truncated at
Kimball, at
US 16, as
US 281 supplanted the SD 45 designation to the south. In the early 1950s, when US 281 was relocated several miles to the east, SD 45 was extended back south to SD 50.
Around 1970, SD 50 had been realigned to intersect
SD 44 west of
Platte, and SD 45 was extended south along the old alignment to Platte, where it remains today.
The north end of the route has remained in its current configuration since 1936.
