Covington’s main commercial corridor continues to fill as two more empty buildings on U.S. Highway 278 are being filled by new businesses. An America’s Car-Mart dealership is opening at the long-vacant Exxon gas station on U.S. Highway 278 at its intersection with Piper Street, while Covington Fish Market is moving into the former Edwin Bean Coffee House store, just past the Ga. Highway 142 intersection. Arkansas-based America’s Car-Mart is a used-car seller that also finances its car sales through its partner corporation Colonial Auto Finance.
