After , LA 10 crosses into the northwest corner of the city of Bogalusa. The highway enters town on Sunset Drive then zigzags south onto Rio Grande Street and east onto Superior Avenue. At Shenandoah Street, LA 10 intersects LA 60. The highway briefly widens to four lanes as it passes through a commercial area and crosses the Canadian National Railway tracks. LA 10 proceeds briefly onto Carolina Avenue before turning northeast onto Louisiana Avenue, a divided two-lane residential thoroughfare. After several blocks, LA 10 intersects LA 21 (North Columbia Street), which connects to Covington on the southwest and Columbia, Mississippi on the north. The median disappears as LA 10 passes Ponemah Cemetery and becomes an undivided two-lane highway once again. Less than east of the Bogalusa city limits, LA 10 crosses a bridge over the Pearl River and into the state of Mississippi, where it continues as Mississippi Highway 26 (MS 26) toward Poplarville.
