R117 road (Ireland)  The R117 road is a regional road in Ireland. The route (north-south) starts "Harcourt Road" at the end of the "South Circular Road" on the southside of Dublin city centre. It crosses the Grand Canal and goes through the suburbs of Ranelagh, Milltown, Windy Arbour, Dundrum, Sandyford, Stepaside and Kilternan (where it crosses the R116) before passing through "the Scalp" into County Wicklow. In Wicklow it goes through Enniskerry where it veers east to the N11 at "Fassaroe" just west of Bray, this part of the road is colloquially known as "The 21 Bends". The official description of the R117 from the "Roads Act 1993 (Classification of Regional Roads) Order 2012"  reads:  Most of the route is covered by the 44 bus operated by Dublin Bus. The bus route does not use the Dundrum bypass, instead running through the village, and also terminates at Enniskerry village and not at the N11.
