IMPORTANT: If you do not make the initial (right) turnoff to Rawsonville, you are unable to take either the first or second route to SILKBUSH. (The N1 has relatively few on/off places and no "cloverleaf" overpasses.) Your only alternative then is the turnoff to the R43 just before the large Shell station. If you get to the traffic signal ("robot"), you have missed everything and must do a U turn.
