Do you mean Mayans?
Yes but that was a mistake it was the Inca, my bad. They made a road, nowhere as good as the Roman system, from that Andies to their capital.
Well, they even made damn lot of them, if the extent of 40,000 km I just found is exact. They were so efficient that the Inca emperor could eat fresh fish at Cuzco 24h after it had been fished in the ocean.
But, well, a DLC about Americas in the Early Modern Era should not be before a long, long timeā¦
Iām sure we can be confident in that the developers will implement road building when the need arises. If it were possible to build roads at the time of the release late 2018, the player would neither have the materials to do so, nor the need to. Good footpaths are an excellent means of transportation, especially if certain critical places along the path are looked after from time to time, like some logs thrown together where the ground is sometimes swampy. Proper roads, like the Romans famously made, are only really necessary or even remotely feasible, if there is a lot of traffic, and a big organisation to make them. In Neolithic Europe, with extremely low population density, and very limited trade (compared to Roman times), and a complete lack of any state-like organisation capable of hiring hundreds of workers, transporting lots of materials, and then building roads kilometre after kilometreā¦ far away from the reach of any little villageā¦ there would neither be a need for roads, nor a possibility. It would probably be much easier to build a Stonehenge than a road twenty kilometres 
With that said, the need and possibility to build roads will surely arise once our little tribal camp grows into a proper city, with thousands of inhabitants, with productive agriculture, lots of trade, and nice neighbouring city states. So about when the developers release Ancient Cities: Bronze Age

For marshy areas, wooden baly dams would already be a necessity. Could imagine that the path-finding routine should play a certain role. The more NPCs prefer the same route, it will affect the surface and - it will be added to the tribe in its ācollective memoryā āthere is a good way through the marshā. It would also be interesting if paths through frozen rivers and marshes are only passable during the frost period. Conversely, roads could become impassable due to heavy rain or flooding. āBoss, we do not get there anymore, we have to build a raft and try it? Dangerous matter, but if you insist on it ā¦ā

Maybe there could be a trait among our tribe members, that signifies their willingness toā¦ shall we say be solidaric, āsacrifice for the common goodā, to be less willing to āacceptā the tragedy of the commons. A person with high score in this will be more willing to, for example, āimproveā a path that was been flooded or something. Like gathering up a few logs or branches and stuff, and making a part easier to move through. Kind of like people who shovel snow from more than just their own yard, so that other people can get through more easily. But if this tribe member finds that his work isnāt enough (though after doing that a few months, a few yearsā¦ Iām sure thatāll help 
), he might raise the subject to the tribe, and the chieftain. Event: āGreat leader, tribe member Ugga-bugga wants the tribe to work towards making this path traversable, what shall we do?ā - āIt helps everyone, so everyone shall helpā / āIf he wants it, he can do itā / āThat is not an important path, ignore itā.
