Ive never had 2 roads who was main connection between the same 2 spots. Usually the new road i made becomes main connection the minute i delete the old road. It seems like the game does not care about anything except that there must at least be a road connection between the factories and the city they belong to and a road between cities.. Sometimes the connection point of a factory (where goods spawn) isnt where you think it might be, and make the new start the wrong place. I dont have any problems with main connections so far. Anyways gl hf =P
