Illinois Route 176 is an east–west state route in northern Illinois. It runs from Illinois Route 23 (State Street) in Marengo to the southern terminus of Illinois Route 131 (Green Bay Road) in Lake Bluff. This is a distance of 41.28 miles (66.43 km).
Illinois 176 is a two to four-lane arterial in northern Illinois. The eastern terminus of Illinois 176 is unique in that both Illinois 131 and Illinois 176 terminate at that corner; neither state route extends beyond that point in any direction.
While not part of Illinois 176, Rockland Road becomes Scranton Avenue east of Illinois 131, and then becomes Center Street east of Sheridan Road. With an average of a name change every 5 miles (8 km), Illinois 176 is a state route probably easier to refer to by number than by its name.
