The R421 road is a regional road in Ireland which runs southwest-northeast from the R445 south of Roscrea to the N52 north of Tullamore. The route also passes through Clareen, Kinnitty and Killurin. The bulk of the route is in County Offaly with small sections in counties Tipperary and Laois. The route is 50 km (31 mi) long.
The R421 commences south of Roscrea at a roundabout junction with the R445 Roscrea bypass. The route continues through the town as the Limerick Road, Limerick Street and Main Street. Continuing in a northeast direction from Roscrea, the route forms a crossroads junction with the N62 National secondary road at the Lourdes Road. A short distance after it crosses the Limerick-Ballybrophy railway line and passes near Roscrea railway station and continues into County Offaly. At Ballybritt there is a sharp turn on the road. To stay on the R421 one must turn left at Ballybrit. The route continues through The Leap & Clareen. The road joins the R440 road west of Kinnitty which continues through the village. The R421 leaves the R440 east of Kinnitty and continues northeastwards through Cadamstown and continues into County Laois. A few kilometers west of Clonaslee in order to stay on the R421 one must turn left for Killurin. The road to Clonaslee continues as the R422 road. The R421 diverts back into County Offaly through Killurin and meets the N52 Tullamore Bypass at a roundabout junction. It leaves the N52 at Charleville Castle grounds and continues in through Tullamore as the Charleville Road, Cormac Street, High Street, Bridge Street, Columcille Street & Arden Road (all formerly part of the main N52 road). The road terminates at the N52 Bypass north of Tullamore.
The current route designation took form following the opening of the bypasses of Roscrea and Tullamore in the 2001 and 2009 respectively. Prior to the opening of the N7 Roscrea bypass (now the R445 bypass following the opening of the M7) the route through the town known as the Limerick Road and Limerick Street formed part of the N7 road. Prior to the opening of the N52 Tullamore bypass the R421 terminated at its junction with the N52 near Charleville Castle (south of Tullamore) with the N52 assuming prominence through the town.
The N7 road is a national primary road in Ireland, connecting Limerick and Dublin. The majority of the route is motorway standard and is designated as the M7 motorway. At the Rosbrien interchange in Limerick the route continues as the N18 dual carriageway to Shannon and Ennis. The road passes through the midlands of Ireland, and acts as a trunk route out of Dublin for the N8 and N9 national primary routes to Cork and Waterford respectively. It forms part of European route E20.
The M7 motorway is a motorway in Ireland. The motorway runs continuously from the outskirts of Naas in County Kildare to Rossbrien on the outskirts of Limerick City. The M7 forms part of the Dublin to Limerick N7 national primary road. The section of the motorway bypassing Naas, an 8 km stretch, was the first section of motorway to open in Ireland, in 1983. Following substantial works to extend the M7 to Limerick, by the end of 2010, the motorway replaced all of the old single-carriageway N7 route which is now designated as R445. At 166.5 km, the M7 is the longest motorway in Ireland.

The R639 road is one of Ireland's regional roads. Once designated the N8 national primary road, it was reclassified in stages as the R639 following the progressive opening of sections of the M8 motorway, which rendered the single carriageway N8 redundant as a national primary road. By-passed sections of the old N8 were generally reclassified as R639 as soon as a new section of M8 opened, thereby increasing the length of the R639. With the completion of the M8 on 28 May 2010, the R639 now stretches from Durrow, County Laois to Cork, running through counties Laois, Kilkenny, Tipperary, Limerick and Cork.
