Madison Street is a major east-west thoroughfare 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.[1]
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.[2] At one point, the intersection between the two streets was considered the "world's busiest corner."[3]
Notable buildings located along Madison Street include the Carson, Pirie, Scott and Company Building[4], Chase Tower, Three First National Plaza, the Chicago Civic Opera House, Citigroup Center and the United Center.[5]
