The basics: BNA Nashville International Airport recently opened a $115 million Parking and Transportation Center. The facility offers 2,200 parking spaces, a variety of amenities for travelers and a dedicated Ground Transportation Center for commercial vehicles. The six-level garage features the art installation, "Air/Traffic/Control,” by Ivan Toth Depeña, a light and glass sculpture in the elevator lobby on all six levels of the garage. Each glass pillar has four sides showing flight and wind patterns for the airport. Each of the six floors is a different color, creating a dramatic rainbow effect from the outside of the structure.
