I would recommend Charlie Pryors Channel for a tutorial on Roundabouts. I learned his way and its very easy. When using the hotkeys on the top center, its a matter of seconds, laying it in, deleting helperlines and gravel/asphalt it up. JD Plays also uses a tripple road layout for his Highways, neat Idea I copied too. While paving/graveling roads, the footpath dont interrupt the job anymore. Just drag your roadupgrade over them. Although roadintersections do it still. A more realistic way for the customs house would be, making them Non-blocking. That means more trucks can use the paved part at the same time. The stations keep traffic limit down enough. Did it only for the large one, for the medium and small I dont find it realistic or neccesary. Simple line of code in the building ini-file. I also encountered the problem with the demolition not finishing, while there is a vehicle incoming or a line attached to the building. just send the vehicle home or delete the line. Would love to see more republics growing on youtube. PartyElite started a dessert playthrough recently. Maybe you can stream your tropical paradise more?
