When the new Central Passenger Terminal Complex at the Hartsfield Atlanta International Airport opens in September, 1980, it will be the largest airport terminal complex in the world. Four principle elements comprise the design of this facility: (1)Two interconnected, landside terminal buildings; (2)four separate airside concourse buildings; (3)an underground, automated guideway transit and pedestrian mall system, linking the terminal buildings and concourses; and (4)the ground access system. The concept of a centralized terminal with satellite gates will most efficiently accommodate Atlanta's volume of transferring passengers, which accounts for 72% of all passengers arriving at the Hartsfield terminal.
