From the north, I–43 provides controlled access into Downtown Milwaukee. I–94 leads to Downtown from Chicago and other points south and west of the city. If you are traveling to sites in the wider metropolitan area, from I–94 you can connect to I–894, which bypasses central Milwaukee.
Lake Michigan is Milwaukee's eastern boundary; Wisconsin Avenue is the main east-west thoroughfare. Milwaukee's Downtown, the central Business District, is 1 mi long, a few blocks wide, and is divided into east and west by the Milwaukee River. The East-West Expressway (I-94/I-794) is the dividing line between north and south. Streets are numbered in ascending order from the Milwaukee River west well into the suburbs. Many Downtown attractions are near the Milwaukee River and can be reached on foot.
