The second enlargement of COLONIAL PLAZA was performed between June 1972 and October 1973. This project added a South Mall and new Belk-Lindsey anchor store, which replaced the 1956 original. In this 1973 photo, the newly-built mall section extends toward the left.

In a circa-1973 layout, the new "South Mall" concourse appears in light gray. This addition increased the PLAZA MALL gross leasable area to 800,000 square feet. The facility now incorporated over 100 stores and services.
