Highway System
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.
In all, there are 2,185 interstate miles that serve the state, making Illinois the third ranking state in the U.S. There are a total of 15,969 miles of state highways and 7,847 bridges making the interstate route accessible across the entire state. More than 7,200 trucking establishments within Illinois take advantage of this extensive network of highways.
Illinois is also home to seven of the 150 nationally designated scenic byways.
