In the early 1980s the MNAA commissioned Robert Lamb Hart, in association with the firm of Gresham, Smith and Partners, to design a modern terminal; construction began in 1984 and was completed in 1987. It had three main concourses and a smaller commuter concourse radiating from a distinctive three-story atrium.[1] An international wing was built in Concourse A; the airport was renamed Nashville International Airport/Berry Field. It is now rare to see the "Berry Field" portion used, but the airport's IATA code (BNA) is short for Berry Field Nashville, and the military facilities at the airport are still commonly known by this name.
