Most places in Ireland have names, which most people, even people from abroad have heard of. Road numbers are unknown to most people. They are far less clear than words like Belfast, Cork etc.
Neither is it at all obvious that "J xx" on the signs means Junction xx either.
Nothing seems to exist to tell you where or what Junction is Junction number xx - unlike the motorway exits, where in many countries they follow in number order (not in the USA now) xx, xx+1 etc. Here the Junction numbers, if they have a logic, do not seem at all transparent.
Does anyone know what the "Two canted elipses" logo means - some agency or the sign of the Red Cow? Why on a small sign do we need to have two logos taking up space.
The signs are way too low, and way too small, -even if you actually know what they are supposed to mean.
