Interstate 74 in Illinois runs from the Quad Cities southeasterly across central Illinois toward Indianapolis, leaving Illinois into Indiana near Danville. It closely follows the route of US Route 150 throughout its length Illinois, except for the few miles against each state border. The northwestern end of the somewhat diagonal Interstate 74 occurs about 5 to 6 miles north of the Mississippi River bridge, in Davenport, Iowa. From Davenport, Interstate 74 heads south across the Mississippi River into Moline, carrying US Route 6 along for the ride. Interstate 74 in Illinois runs from the Quad Cities south to Galesburg, then southeasterly through Peoria, Bloomington-Normal, Champaign-Urbana, and Danville, to leave Illinois across the eastern border into Indiana, toward Indianapolis.
