FILE - In this May 24, 2013 file photo, traffic begins to thicken as motorists getting an early jump to Memorial Day destinations in Indiana and Michigan travel an interstate freeway through Chicago. Auto club AAA on Friday, May 16, 2014 said it expects a total of 36.1 million people to travel 50 miles or more this Memorial Day Weekend. If that estimate holds true, it would be the largest amount of people traveling during the holiday weekend since 2005. (AP Photo/Charles Rex Arbogast, File)

Its neighbor to the east may claim “The Crossroads of America” title, but by nearly any measure, Illinois is the heart of the U.S. Interstate system.

Illinois has the third highest total of Interstate routes and mileage. Only New York and California have more I-designated roadways, with 7- and 25-million more residents, respectively. Only Texas and California routes cover more mileage, though those states are 5- and 3-times larger by territory.

And the importance of the routes — many of which were designed to pass through or near Chicago, with its access to the global economy — further spell out the importance of Illinois as a hub of trans-U.S. travel. The two longest treks of the Interstate system, I-90 and I-80, pass through Illinois on their coast-to-coast journeys. And two key connections to the Gulf States, I-55 and I-65, reach their nadir in the Chicago area. Add in I-57, I-64, I-70 and I-94 and an Illinois driver can reach almost every population center in the nation by navigating one interchange.     Login or Subscribe to read the rest of this story.
