Playing civilization 5 the game explicitly says roads cost gold to maintain. This is of course a [major variable][2] in the answer to ["should I connect these cities by road or not" question][1].

However, looking at the income report I do **not** see a "road maintenance" entry, and comparing with the number of roads I have it really feels that they do not cost 1 gold per tile, which is what I assumed from the game description. Further, I'm pretty sure building a single road tile does not affect my income.

So, do roads really cost gold to maintain, and if they do - how does it work? Is it really 1 gold per road tile, regardless of where that tile is?
