Have to go from Limerick to Kilkenny later this week. The AA routeplanner is saying M7 to jn 21, then a series of R roads via Rathdowney, Durrow, etc, and entering Kilkenny via the N77.
Is this the best route ?
Looking at the map it would seem better to stay on M7 for longer, but there doesn't seem to be a junction 20, and it looks like you can't take M8 at junction 19 if going northbound.
Any regulars on this trip who could advise best option ?
