Among states, Illinois is 25th in area and and 6th in population but has the 3rd most interstate miles. Here are the top 5 states:

- Texas – 3,233 miles
- California – 2,456 miles
- Illinois – 2,169 miles
- Pennsylvania – 1,759 miles
- Ohio – 1,572 miles
Illinois has the third-largest region in the country by population but its next largest cities are relatively small. Interstates connect all of these population centers, connect to big cities not far beyond the borders of the state (like St. Louis and Milwaukee), and link to places far away. Here is how the Illinois Department of Transportation describes the interstates:
Illinois is at the heart of the country’s interstate highway system. This vast system consists of coast-to-coast interstates I-80 and I-90, along with I-70 that extends from the east coast to Utah. These major corridors are joined by multiple north – south corridors including I-39, I-55, and I-57 and additional east – west corridors such as I-24, I-64, and I-74.
This is in part due to geographic advantages – a particular location along the Great Lakes, connections to major rivers like the Mississippi and the Ohio, and in-between other places – plus developing transportation infrastructure – highways and roads plus railroads and air options in addition to the early water transport.
Indiana may have the state motto of “The Crossroads of America” but would Illinois have a better claim to this? I am not sure it could replace the state slogan “Land of Lincoln” but it may speak more to the current state of Illinois economic and social life.
