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 centers, 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."

A provisional site plan depicts how a revitalized TRI-COUNTY MALL would have been configured. Structures shown in dark gray were built in 2015 and 2016. An abandoned Dillard's was going to be replaced by a dine-in cinema. The shuttering of Sears (August 2018) and Macy's (April 2021), and repercussions of Covid-19, tossed a monkey wrench into the proposed revitalization. 

The Singapore company gave up and sold the virtually vacant TRI-COUNTY property in late 2021. A new plan, for a mixed-use retail, residential, restaurant and entertainment facility, was announced. The complex-to-be would be known as ARTISAN VILLAGE. In May 2022, TRI-COUNTY MALL closed for good, after over 61 years of commerce.
