Belle Chasse Tunnel
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 $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. According to engineers and various 1956 issues of the Plaquemines Gazette, the tunnel is the first fully automatic underwater tunnel in the world as it did not require any operating personnel. The tunnel has ventilation machinery that automatically change the tunnel's air every two minutes with automatic generators taking over if the machinery fails.
