More so than any other neighborhood of Lüm, the City Center is well known for and largely defined by its transportation infrastructure. As mentioned in previous entries, it is effectively the transportation hub of the city, with the two major train tracks and multiple ghostway lines converging at Midtown Station. Travelers can take the ghostway north to Nungunny, west to the Fringe, east to East Island, southeast to Newbridge, or south to the university or the Arts District without having to make any transfers. One ghostway line that doesn't pass through the City Center, however, is Lüm's longest, which skirts the west and south edges of the city... still, enough lines do pass through here to make Midtown Station a constant hive of activity. Several of Lüm's highways also meet in or least cross the City Center, and so drivers are as likely to pass through this neighborhood as those relying on public transport.

Away from Midway Station and the main highways, however, the City Center can be confusing to navigate. While it was originally centrally planned, with a neat rectangular grid of perpendicular major streets, a lack of direction or oversight in succeeding construction and development led to that tidy arrangement not persisting. New buildings were erected blocking some roads while side roads were widened or opened to provide ways around them. Today, the bulk of the City Center is a muddling mélange of order and chaos, with a street running straight for several blocks only to terminate unexpectedly for no obvious reason. Addresses can be particularly confusing, in that the severing of streets has led to many instances of discontinuous parts of roads bearing the same name, so that two addresses nominally on the same street may be connected only by a circuitous route of side streets and bypasses.
