Islandbridge

Island Bridge is a road bridge spanning the River Liffey, in Dublin, Ireland and joining the South Circular Road to Conyngham Road at the Phoenix Park.

Island Bridge and the surrounding area are so named because of the island formed here by the creation of a mill race towards the right bank while the main current flows to the left. The River Camac emerges from a tunnel further downstream towards Dublin Heuston railway station.
