The I-380 Corridor (sometimes just "The Corridor") is a region in Eastern Iowa. In general, the expression is used to describe Linn and Johnson Counties, which are connected by I-380.
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 area is serviced by the Eastern Iowa Airport in Cedar Rapids, which connects the region to Chicago, Minneapolis and various other airline hubs.
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).
