Not one roadway only, but the whole boulevard connection, 246 feet wide, should rise gradually from Randolph Street, and every store and building, both on the east side and on the west side of the parkway, north as well as south of the river, would naturally open on the level of the boulevard, exactly as the shops or hotels open on Michigan Avenue south of Randolph Street. Furthermore, every building facing on the boulevard connection would have direct access to the lower level under the elevation (except for a portion of one block at each end), so that goods could be brought into the buildings conveniently. This lower level, well lighted, ventilated, and protected from weather, would afford ideal conditions for handling commercial traffic. Part or all of it could be solidly filled in if the authorities and the property owners deemed this more desirable; it would not be necessary to have all of the lower level open. From this lower level at street intersections there would be inclined roadways or ramps, giving comfortable facilities for pedestrians or carriages to reach the parkway. It would not be necessary to place these ramps at exactly the points where they are shown in the design; but they could be moved to the east side of the parkway if for any reason that side offered an advantage; or they could be eliminated if considered unnecessary. [Illustration: CXVI. CHICAGO. VIEW OF PINE STREET. The Waterworks tower is shown as a marker in the vista of the proposed boulevard to connect the North and South Sides.] The proposed bridge has two decks. The lower one, being designed for commercial traffic, would provide for the present heavy teaming moving north and south over the Rush Street bridge, without interrupting the teaming during the construction of the new parkway, as the old bridge could be retained until the completion of the new one.
