At the present time the northern limit of this foundation of street circulation on the Lake front is the water-tower on Chicago Avenue, and the south limit is the intersection of Twelfth Street and Michigan Avenue. This avenue or parkway should be made as spacious as possible along its entire length. It should be wide enough to provide two broad parallel roadways: one to be used by those who wish to visit the shops, hotels, or theatres, and the other for the passage of those who do not care to stop on their way through the city. Between these roadways should be a broad sidewalk, and the walk next to the buildings also should be very broad. This roadway should be made attractive by effective planting. The trees framing the boulevard may well be of the clipped variety in order to carry out the architectural effect; and the lamps and other accessories should be designed so as to give finish and unity to the composition. The limit of width is fixed by the physical conditions of Michigan Avenue between Randolph Street and the river. Here the distance between the west side of Michigan Avenue and the west line of the Illinois Central property is 246 feet. Michigan Avenue north of Randolph Street is now 66 feet wide. The business blocks between Michigan Avenue and Beaubien Court are 130 feet deep, and Beaubien Court is 50 feet wide; a total of 246 feet. Therefore 246 feet is the limit of possible width, and this is recommended as the width of the proposed boulevard connection, every foot of which is part of this Lake front parkway—the great base of Chicago’s street circulation.
