Here's a portion of the 1983 Covington business map showing the two blocks bordered by Boston, Florida, Rutland and North New Hampshire Streets. Click on the image to enlarge the view.
On the corner opposite the Southern Hotel, heading east on Boston Street, businesses started with Bridges Drugs (in the old Hebert Drugs space), then The Times Picayune office, Picture This Framing Shop, Blackwells Shoes, Lillian's, Aubert Insurance, Village Woodsmith, the Gold & Silver Exchange, and a Step Up. Joe's Family Shoe Store was on the corner of Columbia and Boston, with Smith Hardware to the south, then L'Escargot Restaurant.
Across from there was the Matador Lounge. On Rutland St., the Country Crafts and Gifts was where the English Tea Room is today, and St. Tammany Homestead was two doors east of New Hampshire Street. A hair salon called Style Setters was on the corner of Rutland and New Hampshire, next to the Christian Science Reading Room, and Ogden Photography was were the Toad Hollow restaurant is today.
Kentzel Printing is still in the same location, as is Citizens Bank and Jeff Bratton's law office.
