The terminal exists beneath a public park that forms its roof, thus conserving precious land for green, public use. Below rests a vast, underground, three-level concourse lit by a unique, earthform bridge forming a gateway to the city.The monumental skylight offers travelers in the terminal the illusion of being at ground level. Finally, a 260 foot-long glass observation bubble floats on steel legs above the park, providing spectacular city views and an arena for public functions like cultural openings and photo shoots. The three levels of the terminal effectively constitute an upside down airport layout. Three boarding pavilions connected by underground moving sidewalks to the main terminal stretch for a kilometer along a waterfront wharf. They emerge at intervals to dock three 240 meter boats simultaneously.
