 Its name alludes first to its location within the nine-block North Bridge complex and to the literal distinction of the shopping center incorporating four-level enclosed bridges over both east Grand Ave, and north Rush Street.When Westfield owned the mall, confusingly, "Westfield North Bridge" typically refers only to the enclosed mall, but Westfield holds a retail management contract for the entire North Bridge complex, which includes another multistory retail complex (two blocks north, at 600 N. Michigan Avenue) built in 1995 and street-level retail spaces throughout the complex.North Bridge also includes five hotels (three Hilton, two Marriott), three parking garages, and two office buildings, housing the American Medical Association and Euro RSCG.
