The road has an unfortunate habit of managing to steer clear of many key routes and destinations. It begins not in Dublin City Centre but on Harcourt Road, close to the original city limits. It crosses Grand Canal on Charlemont Bridge and then runs through Ranelagh.
At Milltown Park, the R117 turns off the route to Clonskeagh and instead heads into Milltown. Before Dartry, it turns off again and crosses the River Dodder on Milltown Bridge. Passing through Windy Arbour, it runs under the Luas and by-passes Dundrum Town. It avoids a junction with the M50 and runs around Sandyford, becoming more calm as it heads towards Enniskerry.
The end of the road is unceremonious, as it meets the busy N11 dual carriageway with only the option to head back north.
