Illinois State Route 3

Illinois route 3 goes from Grafton northwest of St. Louis to Cairo in southwestern Illinois. Southeast of St. Louis, it closely parallels the Mississippi River and is a fairly scenic route in places. The vast majority of the route carries the Great River Road route.

The original Illinois 3 went from Morrison to Cairo via Moline, Beardstown, Virginia, Jacksonville, Alton, and East St. Louis in a zag-zag path.
