River Liffey, Dublin Ireland

The Liffey is a river in Ireland, which flows through the centre of Dublin. Its major tributaries include the River Dodder, the River Poddle and the River Camac. The river supplies much of Dublin's water, and a range of recreational opportunities. The river was previously named An Ruirthech, meaning "fast (or strong) runner". The word Liphe (or Life) referred originally to the name of the plain through which the river ran, but eventually came to refer to the river itself. It was also known as the Anna Liffey, possibly from an anglicisation of Abhainn na Life, the Irish phrase that translates into English as River Liffey.

Dividing the Northside of Dublin from the Southside, the Liffey is today spanned by numerous bridges, mostly open to vehicular traffic. Notable are the West-Link Bridge on the M50 motorway, the Seán Heuston Bridge and O'Connell Bridge. There are 3-foot-bridges in the city: the Millennium Bridge, the Seán O'Casey Bridge and the Ha'penny Bridge. In December 2009, the new Samuel Beckett Bridge opened. between the Seán O'Casey Bridge and the East Link Bridge, It was designed by Santiago Calatrava Valls, who also designed the James Joyce Bridge that spans the Liffey. The Samuel Beckett Bridge takes both road and pedestrian traffic and in the future it may also take rail traffic. Crossings further upriver include the Liffey Bridge at Celbridge, "The Bridge at 16" (a 19th-century pedestrian suspension bridge at what is now the K Club), and the Leinster Aqueduct – which carries the Grand Canal over the Liffey at Caragh.
