Like many other areas in the Midwest, the I-380 corridor's cities were settled due to their proximity to nearby rivers. Iowa City was the original capital of the state.
The region is most closely associated with I-380, which connects the region to Waterloo. However, it is also accessible via I-80 (from the Quad Cities or Des Moines), US 151 (from the Amana Colonies or Dubuque) and US 30 (from Clinton or Ames).
