It’s one arterial road. I have lived in a city like that. The first arterial road has homes and businesses and then as population grew, new parallel roads are built. But now we have to have inter city and intra city transport as two diff systems. What I suggested was to have inter city mobility underground and intra city transportation over ground..and many cities can be joined and networked like so.
