Actually, you need an airport to make roads, but why do I need an airport to make/modify a road in downtown of a city for example?
I am actually handcrafting a scenery of an airport, but only modifying existing generic buildings and adding new ones missing, and I need to make some roads… why do I have to go all over the process to enter an airport to make then?
Thanks for your vote…
