Madison Street (Chicago)
Madison Street is a major east–west street in Chicago, Illinois. Prior to human intervention, the Chicago River emptied into Lake Michigan at the present day intersection of Madison Street and Michigan Avenue.
Per a 1908 decision by Chicago's city council, Madison serves as the north–south dividing line for Chicago's street numbering system, while State Street serves as the east–west line. At one point, the intersection between the two streets was considered the "world's busiest corner."
Notable buildings located along Madison Street include the Carson, Pirie, Scott and Company Building, Chase Tower, Three First National Plaza, the Chicago Civic Opera House, Citigroup Center and the United Center.
