Dillard's acquired Mercantile Stores, based in nearby Fairfield, Ohio, in 1998. In 1999, the Arkansas-based chain rebranded the TRI-COUNTY McAlpin's. Demoted to a Clearance Center in 2013, the store would be permanently shuttered in 2015.

Competition from KENWOOD TOWNE CENTRE and several new lifestyle complexes had sent TRI-COUNTY MALL into a downward spiral by the 2010s. A Singapore-based company bought the complex in 2013 and envisaged a massive renovation and repositioning. The 27 million dollar project was to create an enclosed and open-air "power mall."

Eventually, the Singapore company gave up. They sold the virtually 
vacant property. A new plan, for ARTISAN VILLAGE, was announced. 
TRI-COUNTY MALL closed for good in May 2022, ending over 61 years 
of commerce. By 2024, the potential mixed-use redevelopment had 
been renamed. It would now be known as CITY CENTER SPRINGDALE.
