Illinois Route 121 between Lincoln and Morton was upgraded to Interstate 155 on October 29, 1992 with the opening of nine miles of freeway, between a point north of Hartsburg to a point south of Hopedale. This completed the 31 mile long route first discussed in the 1950s.1

Late 1960s costs for the freeway were estimated at $58.7 million, with four-laning of IL 121 between Hartsburg and Emden completed soon thereafter. A lawsuit filed in the 1970s by a landowner whose property was to be cut halted work and required a more thorough environmental impact study (EIS) to be filed. This delayed work for 12 years until the injunction was lifted in 1986.1

The first stretch of limited access highway opened for IL 121 joined IL 98 (Birchwood Avenue) at Morton with Interstate 74 on November 22, 1989.2 Interstate 155 was completed at a total cost of $120 million.1
