In a circa-1986 plan, an eastward expansion completed in 1970 is indicated in dark gray. It was anchored by Joske's. A Northwest Wing (in medium gray) came inline in 1985 and was anchored by Marshall Field's. The Northeast Wing (in lighter gray) opened in 1986 and included Saks Fifth Avenue. The west end Foley's had joined the mall in 1981. The store was expanded as the two north wings were being built in the mid-1980s.
