The Morning Astorian

Chicago, Nov. 18.-George W. Jackson, an engineer, has submitted to the council committee on local transportation plans for an underground loop system. They make it practicable and serviceable to put in operation the one fare streetcar proposal without the issuing of transfers; make grade crossings at intersections unnecessary, enable cars from the different divisions of the city to be transferred to whatever division they may be directed to, provide a 10-foot walk for passengers to go underground to any station desired, give room for municipal utilities and appliances of corporations operating under license, as well as for utilities the city may wish to install, leaving space for future development; take care of the present sewers, and make provision for a new sewer system in connection with a high pressure water system.

The subway proper and the loops are located in the plans between Twentieth street and the Chicago river, with two branches west of Halstead street, one branch north to Ohio street, and one branch south to Eighteenth street. The total length of the subway and routes suggested is 50,703 lineal feet, and the estimated cost is $18,577,318. The engineer says the work can be completed in 30 months.

The subway called for by the plans is of sufficient width for the two tracks for street cars. It is 20 feet below the surface and 15 feet over the freight tunnel, a large part of which is already completed.
