Louisville's Stewarts chain added a second anchor store to WASHINGTON SQUARE. The 3-level unit covered 135,000 square feet. It featured a Psychedelic Shop, which carried mod fashions for teenage girls. There were also a full-service bridal department and home furnishings and accessories section.

Sears was enlarged in 1966-1967 (shown in dark gray). As the Stewart's store was being built later in the 1960s, a modest mall expansion (in light gray) was completed. This added 27,000 square feet and eight stores. WASHINGTON SQUARE now encompassed approximately 517,000 leasable square feet and housed thirty six tenant spaces. By the time of this circa-1973 plan, a twin cinema had opened in the periphery of the mall.

The south anchor store at WASHINGTON SQUARE was rebranded as an Indianapolis-based L.S. Ayres in November 1985. As part of the transition, the store was given an exterior face lift.

Meanwhile, a new Tri-State shopping hub had opened in August 1981. EASTLAND MALL covered 800,000 leasable square feet and contained 119 tenant spaces.

Following the completion of EASTLAND, WASHINGTON SQUARE was substantially remodeled. Sears was enlarged for a second time (in light gray). Likewise, a new main entrance was created, which accessed a 10-bay food court. An East Wing was also added, with the interior and exterior of the mall being refurbished. When construction dust settled in August 1987, the complex covered around 541,000 leasable square feet.
