The Main Street Covington program is set to undergo some major changes as local officials, led by Covington Mayor Ronnie Johnston, seek to consolidate and improve efforts to increase tourism and retail business growth. The Covington City Council voted unanimously Monday night to contract with the Covington-Newton County Chamber of Commerce to run the Main Street program, instead of the having a government employee handle the task. Longtime director Josephine Kelly, a city employee, recently announced her retirement.
