Route description
IL 176 is a two- to four-lane arterial in northern Illinois. The eastern terminus of IL 176 is unique in that both IL 131 and IL 176 terminate at that corner; neither state route extends beyond that point in any direction.
IL 47 overlaps IL 176 east of Marengo.
History
Future
The village of Wauconda hired an engineering firm in 2014 to suggest improvements to the congested interchange with US 12. They proposed eliminating the interchange and converting it to an at-grade intersection with dual left turn lanes at each leg, two lanes in each direction for IL 176, three lanes in each direction of US 12, and developing the frontage of the intersection. The estimated cost to convert the US 12 interchange with IL 176 and the US 12 interchange with IL 59 to at-grade signalized arterial intersections is $300 million, none of which would come from IDOT.[4][5]
