Because Newport is still being constucted, there is almost no air traffic at all, except for what construction vehicles fly between the towering (and for now, mostly empty) buildings. Ground traffic is also minimal, as many areas are still cordoned off due to ongoing construction. Until more of the city is completed, most citizens are content to rely on Newport's elaborate underground rail system to get from place to place.
Fully ninety percent of the city's population is comprised of equal parts construction crews, who work around the clock erecting the gleaming metropolis, and miners, who collect the ores that have brought everyone here in the first place. The remaining ten percent are merchants, entrepreneurs, retirees, and entertainers, all eager to enjoy the spoils of the beautiful city that has been constructed, it seems, just for them.
