Covington Mayor Ronnie Johnston and Main Street Covington board chair Serra Phillips visited merchants on the square Wednesday morning to explain, and at times sell, the mayor’s plan for the new direction of the Main Street program and the county’s small business scene. Johnson’s proposal to move the Main Street program under the Covington-Newton County Chamber of Commerce is the latest in a series of moves he hopes will lead to more new businesses and new jobs in Newton County. He’s working to garner support in the community for his initiatives.
