Route description

Illinois 120 forms part of old U.S. 14 through Woodstock before turning east towards Waukegan. It passes through the cities of McHenry, Volo, and Grayslake before becoming a four-lane divided highway west of Interstate 94 (Tri-State Tollway). It overlaps Illinois Route 31 through McHenry.

In McHenry the road is also called Elm Street, and east of Grayslake, the road is also called Belvidere Road, although it does not go through Belvidere.

History

SBI Route 120 originally ran from Havana to Mason City in west-central Illinois. In 1939 this became Illinois Route 119, and in 1951, U.S. Route 136. In the meantime, in 1941 Illinois 120 replaced Illinois Route 20 to avoid confusion with nearby U.S. Route 20. In 1972, the designation was removed east of Illinois 131.
