The raised streets needed new, raised sidewalks to match them. In the case of vaulted sidewalks, which might be 5 feet (1.5 m) or more over the original street level, a structure was built to hold a new sidewalk at the new street level, and an empty space was left between the original and the new sidewalks.

[1] Viewing most of the defects as minor or non-existent, the city began filing the maps away unread, in an attempt to argue in court that the unread maps did not provide ...
In January 1858, the first masonry building in Chicago to be thus raised—a four-story, 70-foot-long (21 m), 750-ton (680 metric tons) brick structure situated at the north-east corner of Randolph Street and Dearborn Street—was lifted on two hundred jackscrews to its new grade, which was 6 feet 2 inches (1.88 m) higher than the old one, “without the slightest injury to the building.” [9 ...
