After nearly two years of construction, the $2,436,000 structure opened in February 1956 with the Canal beginning operations later that year. The politicians in Plaquemines Parish chose to construct a tunnel as opposed to a drawbridge as to enable continuous flow of traffic."@en . "590.702"^^ . . . .
