Michigan Avenue is named after Lake Michigan, which it once ran alongside at 100 east in the city's street numbering system until land reclamation for Grant Park (then Lake Park) pushed the shoreline east. The one-sided street feature is due in large part to the legal battles of Aaron Montgomery Ward with the city over cleaning up the park and removing most of the structures in it. Ward opposed the development of Grant Park with public buildings along the lakefront except for the Art Institute of Chicago Building. Eventually, Ward's ideas were adopted by Daniel Burnham in his Plan of Chicago, which called for "insured light, air, and an agreeable outlook" along the Grant Park street frontage. The preservation of the lakefront view has inspired architects to create an architectural cornucopia of designs along the "streetwall".
