The N21 road is a national primary road in Ireland. The route runs from the M20 outside Limerick to Tralee with connecting roads to other parts of County Kerry. It is 84.37 km (52.43 mi) in length. It runs through the towns of Abbeyfeale, Newcastlewest, Adare and the village of Templeglantine. Prior to October 2010 the N21 also ran through the town of Castleisland. The town has recently been bypassed.
The N21 route commences about 8 km (5.0 mi) southwest of Limerick city, just beyond Patrickswell. At the junction, which is reached by the main M20 motorway, the N20 diverges south to Cork and the main dual-carriageway becomes the N21 west.
Prior to the 2001 opening the new dual-carriageway, traffic to Kerry left the city on the old N20 in a southwest direction on the Ballinacurra Road through Raheen and then went through Patrickswell to the beginning of the N21.
The new 11 km (6.8 mi) M20/N21 dual-carriageway route begins at junction 1 on the Rosbrien Interchange as the M20 where it leaves the M7/N18 Limerick Southern Ring Road, and bypasses the Limerick suburbs of Dooradoyle, Raheen and Patrickswell, and continues, as the N21, almost to Adare. At this point the N21 becomes a standard two-lane road and flows through the main street of the scenic village.
