[edit] Route description
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.
[edit] History
Construction of I-180 was completed in 1969.[1] 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 2,000 – 3,450 vehicles per day as of 2005.[3]
