The head of the governing body of the Louisiana Superdome says the $85 million renovation of the stadium will be finished in time for the Essence Festival over the Fourth of July weekend. Construction crews are expected to be gone by June 29 – just five months after tearing down much of the stadium’s lower bowl. Workers have changed the configuration of the lower bowl, increasing football seating by 3,400, while widening the plaza concourse, building two bunker club lounges and adding additional concession stands.
