The Terrytown Winn Dixie closed last fall to be converted into an Aldi. Another one in Algiers was supposed to close also and re-open as an Aldi, but it appears to be hanging on as a Winn Dixie for now.
There's one more West Bank Winn Dixie, in Marrero. There's already an Aldi in Marrero, so maybe that Winn Dixie will be kept around.
