It is proposed to extend the freight lines to the Lake front piers and harbors. The excursion-boat piers, as well as the recreation piers and those at the harbors, are to be thus connected. It is probable that many of the present freight houses of the railroads will remain and carry on their functions as at present, except as to goods now hauled into and out of Chicago, although intended solely for outside trade. As they are already connected by tunnel, they can be and will be used for the city-consumption trade, and to supply the great number of smaller retailers and others who cannot afford to operate separate individual freight elevators from their shops to the tunnel railroad. At the present time much of the near-by farm stuff for housekeepers, hotels, and restaurants is brought into the city on wagons which load late in the afternoon and travel at night, reaching the general market at South Water Street or West Market at dawn. Much if not all of this freightage can be done cheaper to the truck farmers, and more satisfactorily to the consumer, by cars run at night on the trolley and elevated lines. Between one and seven o’clock in the morning these roads should render this important service. The saving of wear and tear on roadbeds due to the elimination of heavy teaming is, all by itself, enough to recommend the adoption of the above suggestion. Besides, the convenience of both producer and consumer is to be considered, and also the saving of time and the cheapening of provisions. The proposed street plan of Chicago is based on a system of circuits and radials. This is also true of the railroad and traction systems. As shown on the accompanying diagrams, the heart of Chicago is surrounded by a circuit of railways, which may be said to follow Michigan Avenue, Canal Street, Sixteenth Street, and Kinzie Street. Following the same lines, a subway circuit may be constructed for handling freight, and another for passengers, the latter running, however, on Twelfth and Washington. To this circuit would be tangent three others enclosing areas increasing in size around the center of the city as above described. By means of these circuits a complete system of distribution of passengers and freight may be secured. To the inner circuit will relate the various services of distribution of the elements of life, produce, and commodities for manufacture; and on it should be placed the freight substations, the markets for general produce, the main post-office, and postal substations. The various services for water, sewers, power, telephone, and telegraph, also may be schemed on the inner circuit as a basis. To it will also correspond the inner circuit of boulevard circulation.
