So I just wanted to upgrade my roads from the basic road to a wider one. I tried to click on the road and look for upgrade. Nope. Can’t be done. So I did the next logical step: Maybe if I build the new road on top of the old it will understand that and it upgrades. (Some game had this type of upgrading.)
So I did that. I did it on just a tiny bit of the long road and it went hilariously. See for yourselves:
(Also don’t worry I didn’t save it so I will just reload my old save).
