The design for the aviation ports of harbour

I would have two round junctions' at either end, and a path with a two-tear run way, one for incoming planes' and the opposite for out going planes.

With a lower bridged- deck that would act as a miniature air Port booking station.

I would have them seated around the coastal areas' as so to, ease air port congestion.
Of course, percentage would be seated with my other half.
