With the StreetsMod, you can build your own realistic streets with arrows, lines, manholes  and many more cool stuff. You don't need any additional mod, but it's recommended to have  stairs (default), wool (default) and bucket (default) installed. It's easy for you to  enable/disable certain parts of this mod because it's organised as a modpack, which you can  configure in Minetest's Main Menu -> Configure.
If you have any criticism, ideas etc, feel free to tell me! :)
