Grand Avenue is a major east-west street in the city of Chicago and nearby DuPage County, although it deviates somewhat from Chicago's grid system, as it is diagonal west of Western Avenue. The street runs from the Kingery Highway (also known as U.S. Route 20 and Illinois Route 83) in Addison, east through the western suburbs, and then east-southeast into Chicago, through the Magnificent Mile shopping area, and continuing out to Navy Pier, where it ends. This is a distance of about 19 miles (31 km).
