 The final part of the expansion, a two-story, McAlpin's department store, opened as the mall's fourth anchor store one year later.It was the 100th department store to be opened by parent company Mercantile Stores Company, Inc., and it was designed by the same architectural firm that handled the mall's enclosure in the late 1960s.To add McAlpin's, mall developers had to seek approval from the Lazarus chain, which under the terms of its lease had to approve the addition of any anchor stores to the mall.
