It is not, however, necessary to carry the connecting boulevard very high. The present grade of Michigan Avenue at Randolph Street can be raised one foot, or a little more, without difficulty, so that from the street level at this point to the level of the boulevard connection one block north, at the corner of Lake Street and Michigan Avenue, the total rise would be about eleven feet, with a grade of two and seven-tenths per cent. From Lake Street to South Water Street the surface of the boulevard connection would rise only three feet more on a grade of three-fourths of one per cent. North of South Water Street the surface would rise very slightly to the bridge, from which point it would continue to the north practically on a level, until descending on a gentle grade to Lincoln Park Boulevard, near Indiana Street, or to Ohio Street. The grades suggested are less than those existing on Fifth Avenue in New York. [Illustration: CXIII. CHICAGO. PLAN OF MICHIGAN AVENUE FROM TWELFTH STREET TO THE RIVER, AND ITS EXTENSION ON PINE STREET TO CHICAGO AVENUE. The proposed double roadway is designed to accommodate the immense volume of traffic which will be attracted to the Lake front. The west roadway cares for shopping traffic and carriages waiting for the crowds attending public functions; the eastern roadway carries traffic through the business section without interference from stationary vehicles. The boulevard proposed is raised above the three streets north and south of the River (as shown in illustration No. CV), thus creating an artery free from heavy teaming traffic at its crossings from the North to the South Sides. A double-deck bridge accommodates the north-and-south traffic-teaming below light vehicles above. COPYRIGHT, 1909, BY COMMERCIAL CLUB OF CHICAGO] [Illustration: CXIV. CHICAGO.
