That's fine as the simplest case, where there is only one single continuous line. But it fails with anything more, and needs to be explored further. Eg someone could draw in even more detail for different parts of it. The arrival and departure are on different floors, and there's an inclined section in between (the departure splits into 2 sides, so 3 parallel lines). If all of them have `=jet_bridge` (eg 12 `way` in total) , it would be very confusing and complicated.
