Louis Armstrong New Orleans International Airport (MSY) in the US has inaugurated its $1bn terminal to accommodate rising air traffic.

The 35-gate North Terminal was designed by Pelli Clarke Pelli and Manning Architects in partnership with Crescent City Aviation Team (CCAT), which is a joint venture of Leo A Daly and Atkins.

As well as leading the terminal design, CCAT designed the concession programme, three concourses and two parking garages.

Aviation radar and electrical facilities, pump station, airside aprons and landside roadway systems were also designed by the firms.

According to its architects, the terminal’s design is inspired by the culture, geography and history of New Orleans and emulates the ‘soft curves’ of the Mississippi River.

The airport also has a single security checkpoint for foreign and domestic flights and is capable of accommodating large tourist crowds during Jazz Fest, Mardi Gras and other local festivals.

The terminal has a spherical roof that can handle long, heavy showers, while the airport’s glass curtain wall can endure high-speed winds.

The terminal includes Concourse A with six gates. The concourse was added nine months after construction to handle rising demands.

Atkins Intermodal business unit director Justin Jones said: “We are extremely proud to have supported the city of New Orleans in bringing the new North Terminal to reality.

“This beautiful, state-of-the-art facility will not only provide a modern, spacious place to arrive and depart but also bring a taste of what makes New Orleans unique, including its music, food and culture.”

Leo A Daly president Steven Lichtenberger said: “The new MSY establishes an iconic new gateway to the city of New Orleans and a passenger experience unlike anything else in the world.”
