Illinois Route 120 (IL 120) is a major east–west state highway in northeastern Illinois. It runs from U.S. Route 14 near Woodstock to Illinois Route 131 in Waukegan. It travels a distance of 34.62 miles (55.72 km)[1] and is one of the few roads that provides direct access from McHenry County to Interstate 94 (Tri-State Tollway) in Lake County. Throughout its length, it shifts between two and four lanes as it passes through a setting that consists of open rural areas, as well as larger developments and heavy congestion.
Although small capacity expansions have been made over time, a lengthy two lane section of road in the Grayslake vicinity has yet to see any major expansion. This key segment has been the subject of much debate regarding the greater traffic flow across north-central Lake County. In October 2009, a special council approved a unified vision for a plan for most of the Lake County portion of Illinois 120, which includes a long discussed bypass around downtown Grayslake.
