Current Information


The Illinois Department of Transportation (IDOT) recently completed improvements in the IL 120 Corridor. The project included interconnecting and synchronizing the traffic signals along IL 120 from US 45 to IL 134, as well as the addition of a right turn lane at west bound IL 120 and Hainesville road. The traffic signalization is coordinated through Lake County PASSAGE. While there may be a few remaining punch list items to complete, the surface is down, the road is striped and the permanent signals have been turned on (signal retiming work still underway). These improvements are expected to improve traffic flow along IL 120.
