The Birdhill Tidy Towns group has a heritage trail on its website and it was there that I first heard of the Dunally Line, AKA the R496. Tipperary North Riding County Council also uses the name [.DOC] and it is also used in several places on OpenStreetMap.
I would like to know more about the date, purpose and circumstances of the construction of the Dunally Line.
