I-155 was created to replace Illinois Route 121 (IL 121). Prompted by safety concerns at a major intersection near Morton, state transportation officials replaced the entire route with a limited-access freeway. The Interstate was built in several segments from 1970 to 1992, a period that included a 10-year delay due to a lawsuit over right-of-way. I-155 fully opened to traffic on October 29, 1992.[2][3]
