The R110 forms an important route through Dublin, and out to the west.
It begins on the R138 at St Stephen's Green, and heads westwards. It starts as a dual carriageway: it was due to become part of the Inner Tangent, and was eventually upgraded to meet the R137 Western Tangent. This explains the large junctions, especially near St Patrick's Cathedral where a huge diamond interchange was once planned.
This junction was once known as the "The Four Corners of Hell" because of the badly-reputed pubs on each corner, but those were all removed to make space for the road.
The Coombe and Cork Street managed to survive any destruction, despite it once being proposed, and at Dolphin's Barn there is a brief return to dual carriageway as it crosses Camac Bridge.
After running through Crumlin and Walkinstown on the Long Mile Road, the area becomes more industrial. It meets the Naas Road at a large gyratory, where it used to give way to the N7, but now the R110 continues along the dual carriageway to the Red Cow Interchange.
