Armitage Avenue is an east-west street in Chicago and its western suburbs, being located at 2000 North in the Chicago address system, two and one-half miles north of Madison Street. Its west end is located at Addison Road in the western suburb of Addison. In the western suburbs, it is a minor road, being split into many segments, usually by freeways. Armitage Avenue becomes a major street at its intersection with Grand Avenue in Chicago, continuing east until Mendell Street, just east of its interchange with Interstates 90 and 94 (Kennedy Expressway), and just west of the North Branch of the Chicago River. Immediately east of the river, it resumes as a minor road, beginning at a cul-de-sac, heading east until Southport Avenue. At Racine Avenue, Armitage Avenue is once again a major street.
