Crikey a quiet dual carriageway
+1 Superb photo.
As for French dual carriageways; one of the delights for us of using Roscoff when we go to France, are the roads once past Morlaix.
Whether we are heading to Le Mans (as per next year) of heading south, we opt to use similar dual carriageways.
Their 110km/hour speed limit is our 4/4s perfect cruising speed; relaxed and economical.
