Oh No! When did they say this? Please tell me we're not stuck with separate highways and 3 bridge types!
In the AMA someone asked the question and they said it was not something they were working on.

1) Roads! I think you can agree that roads make up a big chunk of the city builder genre. Although the current range of roadtypes provided by the game are a good basement, there are endless possiblities and ideas on increasing the variety (road textures, road(-side) decorations, lane management, bus lanes, speed limits, pedestrian areas, ...). Do you have any plans on working on that? Maybe even giving the community tools like an asset editor for roads?

1) We love roads. Unfortunately having to go too deep with the roads can start feeling too much micromanagement and therefore we're not planning to go too much into details with them. However a couple of things we have discussed and are looking into: naming the roads, new road options/policies and figuring out if the roads could be made moddable. I have no eta on any of these, just telling you guys what we are thinking would be cool.

Thanks for the AMA!!! C:S is awesome and you guys are awesome for making it.
1) Any plans on adding other public services to the game beyond garbage/water/power/health/police/fire, like postal services? I don't think I've seen a city builder with post offices before.
2) The districts in C:S are a great idea and something I think we'd all like to see expanded. Any insight about what we can expect in the future with districts, like entertainment district, museum district, European/W2W district, pedestrian only, national parks, historic district, etc.
3) 4-lane one way roads in the future? Yes/no?

4) Any plans to add more park options? Zonable parks, national parks, streams (drawable like paths), outdoor recreation, etc are just a couple ideas.
5) The european style W2W buildings are awesome! Can we expect any other world architectures to be represented in game? Asian, russian, middle eastern, etc.

1) Not in the near future, but you have nice idea there. 2) We're looking into working with the districts more.
3) Maybe, we don't have plans to add new roads currently, but in the future why not. 4) Good ideas, adding to the wishlist. 5) I would love that, though the asset heavy stuff take quite a lot of time.

So I think the most you are going to get is probably a road being modable which I guess is better really.... personally I would rather they put effort into what is a game feature, than the purely decorative feature of naming roads.
