Interstate 155 (I-155) is a north–south spur of I-55 that provides an Interstate connection for the Illinois cities of Peoria and Lincoln. The northern terminus is just east of Peoria, at I-74 exit 101 in Morton. The southern terminus, which is northwest of Lincoln, is located on I-55 at exit 127. The highway is 32.13 miles (51.71 km) long.[1]

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]
