Second--The passengers in the low level subways would be about 40 feet below the surface of the street, thus necessitating the use of elevators between low level and high level subways at station points, a distance of about 20 feet. Third--The engineering difficulties and risks that would be encountered in its construction. Fourth--The fact that it would interfere, and to a large extent destroy, existing and contemplated low level improvements The importance of the first objection can be analyzed by comparing the estimated cost of this plan, as shown in Cost Estimate No. 3, Page 236, with the cost of Plan No. 1, as shown in Cost Estimate No. 2, Page 233. The second objection can only be answered by the individual opinion of those who might-ride upon the system. In my judgment it is Tmt serious. The third objection, or the engineering difficulties and business risks to be assumed during the construction of such a low level street car subway, is difficult, and would require the exercising of great skill and care during construction, but can be overcome and is in my judgment comparatively small when compared with the advantages to be gained by the adoption of such a system. The fourth objection is, in my judgment, difficult to overcome, as the changes that would necessarily have to be made in the existing and contemplated low level improvements of the Illinois Telephone and Telegraph Company to make room for the low level subway herein contemplated would probably involve heavy expenditure of money, and the relative importance of the advantages to be gained by the high and low level system of street car subways as compared with t...
