If anyone remembers, there was this very old add-on that was around in 2008. It was the autoroad mod. I cannot seem to find the add-on, no where on RTB or Blockland Forums.
What this addon did was automatically placed roads and changed them to the correct road type to fit the road system. This add-on in my opinion was very useful and I am sad to see that I cannot find it. If anyone has this add-on, or could possibly re-create this. It would be greatly appreciated.
