The N78 north of Newtown, Co. Laois
The N78 runs from the N77 at Hennebry's Cross, 6 km north of Kilkenny, to junction 3 of the M9 at Mullamast near Ballitore in County Kildare, by way of Castlecomer in County Kilkenny, the southeast corner of County Laois, and Athy in County Kildare.
Although once – as the old T6, which joined the T5 at Naas – a part of the main route from Kilkenny to Dublin, that role is today chiefly performed by the M9 / M7, and the N78 chiefly serves to connect Castlecomer and Athy to the rest of the national network.
At the opening of the first stage of the M9 in 1994, the N78 ran to the motorway's then southern terminus, junction 2 at Kilcullen. When the M9 was extended southwards in 2009, a new direct link was built from Athy to junction 3 of the motorway at Mullamast, and this link then became the final section of the N78, the old route north of Athy being reclassified as the R418.
