The most prominent transportation route in Nungunny is, of course, the always busy highway that runs from the edge of the city to the north through Nungunny to the Cottages and beyond. Most of the people using this highway, however, are either only passing through, or are stopping at the establishments right at the side of the highway. To those living in the residential areas beyond the thin ribbon of hotels, factories, and offices lining the highway, the highway is nothing but an obstacle that separates the two parts of the neighborhood. It is not, however, an impermeable barrier. There are several bridges across the highway; in other places the highway is elevated enough above the ground for pedestrians and small vehicles to pass under it. In a some places there are even portals connecting the two sides of the highway, the result of a brief impulse for civic improvement by the city government a hundred years ago. In any case, despite the highway running between them, West and East Nungunny have far more in common with each other than they do the immediate environs of the highway itself.

Away from the highway, Nungunny is mostly a maze of twisting roads, the result of the haphazard growth of the neighborhood rather than of any sort of plan. Most of these streets are not much more than series of wooden planks laid over the marsh, and while the residents do their best to maintain them, parts of them often fall into disrepair. Aside from the highway, there are no major roads connecting Nungunny to adjacent neighborhoods, though of course there are many small streets, frequently used by those residents of Nungunny who work elsewhere.

A small spur of the subway extends into Nungunny, but the subway station is by the highway and this subway route is much more used by and more useful to the people commuting to the factories and offices along the highway than it is to and by the neighborhood's residents.
