Louisiana (Spanish: La Luisiana, [la lwiˈsjana]), or the Province of Louisiana (Provincia de La Luisiana), was a province of New Spain from 1762 to 1801 primarily located in the center of North America encompassing the western basin of the Mississippi River plus New Orleans. The area had originally been claimed and controlled by France, which had named it La Louisiane in honor of King Louis XIV in 1682. Spain secretly acquired the territory from France near the end of the Seven Years' War by the terms of the Treaty of Fontainebleau (1762). The actual transfer of authority was a slow process, and after Spain finally attempted to fully replace French authorities in New Orleans in 1767, French residents staged an uprising which the new Spanish colonial governor did not suppress until 1769. Spain also took possession of the trading post of St. Louis and all of Upper Louisiana in the late 1760s, though there was little Spanish presence in the wide expanses of what they called the "Illinois Country". New Orleans was the main port of entry for Spanish supplies sent to American forces during the American Revolution, and Spain and the new United States disputed the borders of Louisiana and navigation rights on the Mississippi River for the duration of Spain's rule in the colony. New Orleans was devastated by large fires in 1788 and 1794 which destroyed most of the original wooden buildings in what is today the French Quarter. New construction was done in the Spanish style with stone walls and slate roofs, and new public buildings constructed during the city's Spanish period include several still standing today such as the St. Louis Cathedral, the Cabildo, and the Presbytere.Louisiana was later and briefly retroceded back to France under the terms of the Third Treaty of San Ildefonso (1800) and the Treaty of Aranjuez (1801). In 1802, King Charles IV of Spain published a royal bill on 14 October, effecting the transfer and outlining the conditions. Spain agreed to continue administering the colony until French officials arrived and formalized the transfer. After several delays, the official transfer of ownership took place at the Cabildo in New Orleans on 30 November 1803. Three weeks later on 20 December, another ceremony was held at the same location in which France transferred New Orleans and the surrounding area to the United States pursuant to the Louisiana Purchase. A transfer ceremony of Upper Louisiana to France and then to the United States took place on Three Flags Day in St. Louis. It encompassed a series of ceremonies held over two days: March 9–10, 1804.

The Judge Perez Bridge, also known as the Belle Chasse Bridge, is a vertical-lift bridge in the U.S. state of Louisiana which carries northbound Louisiana Highway 23 over the Gulf Intracoastal Waterway between Belle Chasse and Terrytown. The bridge is paired with the Belle Chasse Tunnel which carries southbound LA 23. Construction began in March 1967, and the bridge opened for traffic in September 1968. It has been plagued with mechanical issues since it opened. Commuters have had to back down off the bridge due to a malfunction. The bridge was built to relieve traffic from the Belle Chasse Tunnel. It was part of a parish project of four-laning Highway 23 throughout the road's entire length to Venice. According to the Plaquemines Gazette, the $3.3 million structure was built by Plaquemines Parish using its Parish Royalty Road Fund without charge to local taxpayers. Boh Brothers worked on its construction.There have been plans for replacing the tunnel and lift bridge with new and improved high-rise structures, and construction has since started to build a bridge that will replace them.

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. Judge Leander Perez enabled the tunnel's construction by passing a constitutional amendment through the Plaquemines Parish Police Jury. He sold bonds towards construction with the US Corps of Engineers paying the remainder of the construction fees. When the tunnel opened, it was the first underwater tunnel in Louisiana. Shortly after, two new tunnels were built in the state: the Harvey Tunnel which once carried traffic from the Westbank Expressway and the Houma Tunnel. The tunnel was the primary means of carrying traffic to and from Belle Chasse and westbank Plaquemines Parish. Since its opening, hazardous cargo is prohibited from travelling through the tunnel, and numerous additional regulations/restrictions have been enforced. Traffic counts soon overwhelmed the tunnel, and in 1967, construction of the Judge Perez Bridge, a vertical-lift bridge, commenced, and that structure opened in 1968 to serve northbound traffic and, whenever the tunnel is closed for maintenance, southbound traffic. Today, the tunnel is still heavily used by commuters to and from New Orleans and surrounding areas. It sports a solid white line that prohibits passing inside the structure. It also experiences flooding problems fairly often and was one of many structures closed after Hurricane Katrina. There have been plans for replacing the tunnel and lift bridge with new and improved high-rise structures, and construction has since started to build a bridge that will replace them.

The Gulf Intracoastal Waterway West Closure Complex is a part of the New Orleans Drainage System; it consists of a navigable floodgate, a pumping station, flood walls, sluice gates, foreshore protection, and an earthen levee. The complex was designed to reduce risk for residences and businesses in the project area from a storm surge associated with a tropical event, with an intensity that has a one percent chance of occurring in any given year. This project was operated for the first time on August 29, 2012, in response to Hurricane Isaac.
