Route description

The freeway was built primarily to connect Interstate 80 to a steel plant in Hennepin. However, the steel plant closed soon after I-180 was built, and did not re-open until August 2002. Although the steel plant is now operational, I-180 is still one of the least traveled interstates in the nation, serving an average of 2,000 - 2,500 vehicles per day. (For comparable numbers, Interstate 190 connecting O'Hare to Chicago serves 109,000 vehicles per day, Interstate 80 serves 20,900 vehicles per day in that area, and rural Interstate 24 in Southern Illinois serves 15,000 vehicles per day.)
Interstate 180 winds through a forested, hilly area in north-central Illinois. The local topography surrounding I-180 is heavily influenced by the Illinois River. It has four lanes for its entire length.
