The Belle Chasse Tunnel was built starting in March 1954 to accommodate the new branch of the Intracoastal Canal. After nearly two years of construction the $2436000 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.
