But only on the land you've bought, you'll still have a motorway coming to your city outside of that square.
well
a)you can use map editor, destroy all the highways in buildable squares and replace them with any other road.
b)outside the buildable area, (all the squares), there is still land for eye candy where you cannot remove highways you don't wish to see. A solution would be, in creating a "dummy highway road type" that looks like a normal country road but acts as a highway connection. i think devs confirmed that through modding we will be able to come up with new road types. Which means, that for outside the city borders, you will simply drag these dummy highways (that look like normal roads) to the city borders, and then continue with normal roads.
This is just a speculation, i don't know how the game behaves, we should get a comment from the devs about this issue i think
