Caravan road
A caravan route yields gold every turn while it sits inside a city's region.
Gold is flexibility: a rush completes the item at 3 gold = 1 production for units and 2 for buildings, and is not subject to the per-turn draw cap. A caravan route is how you move resources to where production cannot reach in time (Economy).
Combined with a Market in the same region, the two incomes stack.
