The R116 road is a regional road in Ireland which runs east-west from the N11 at Loughlinstown to the R115 in Ballyboden. It runs through the South of County Dublin for its entire length.
The official definition of the R116 from the Roads Act 1993 (Classification of Regional Roads) Order 2012 [1] reads:
between its junction with R117 at Glenamuck South and its junction with N11 at Loughlinstown via Ballycorus Road, Rathmichael Road, Stonebridge Road, Mullinastill Road and Cherrywood Road all in the county of Dun Laoghaire — Rathdown.
East-West: Starts at N11 Cherrywood Road and runs under the old Harcourt Street railway line viaduct and on through Brides Glen where it goes under the M50 and crosses over the Loughlinstown River. Proceeds east along Ballycorus Road to a junction with the R117 in Kilternan. Crosses the R117 at a staggered junction in Kilternan before climbing steeply SW up Ballybetagh Road to Glencullen.
Continues east along the northern side of a deep valley formed by Two Rock Mountain (536 m) and Tibradden Mountain to the north and Glendoo Mountain (586 m) to the south, where it reaches its high point of 287 m (1,263 ft). From the head of the valley it descends steeply through the Pine Forest and continues down through Rockbrook and Edmondstown (where it again passes underneath the M50) to its termination in Ballyboden where it meets the R115.
