In Greensburg, a zigzag was eliminated when a new highway segment was opened in 1994 leading eastward out of town. The old route has been retained as LA 10 Spur. Two zigzags were eliminated in Bogalusa at the Canadian National (formerly the Gulf, Mobile and Ohio Railroad) crossing. LA 10 originally curved north onto Cumberland Street just past the intersection with LA 60 then turned east to cross the railroad tracks on Ontario Avenue. The route then turned south onto Austin Street and east onto Carolina Avenue, proceeding along the current alignment. An eastward extension of Superior Avenue has streamlined this part of the route.
