Since we’re comparing rate of change in population growth since 1970, Harrisburg, south of Sioux Falls, has an even more impressive number: a 2,400% increase since 1970. Construction of the current high school was completed in 2009.

These Landsat images show new roadways being built to connect outlying communities to the main urban area. The bright straight line in the 2022 image is the widening of a road to connect Sioux Falls to Harrisburg. Landsat will continue to record the urban expansion of Sioux Falls and other cities around the world.
