# R113 road (Ireland)

The R113 road is a regional road in Ireland. Located in Dublin, it forms a semi-orbital route around the south of the city. As of 2007, clockwise, it starts at the N31 at Temple Hill in Blackrock and ends at a junction with the N4 at Palmerstown.
The road is one of the busiest Regional Roads in Ireland. The Liffey Valley Shopping Centre, and The Square, Tallaght, two of the busiest shopping centres in Ireland, are both located just off the route. Both the Fonthill Road (in Lucan/Clondalkin) and Belgard Road (in Tallaght) sections also have a number of large retail outlets. The Belgard Road section, running between the N7 at Newlands Cross and the N81 at Tallaght, is a standard dual carriageway and the main thoroughfare in the Tallaght area.
