The Rosie Hacket Bridge is the 21st bridge over the river Liffey between Chapelizod and Dublin Bay.
At the official opening on 20 May 2014, the Rosie Hacket Bridge in Dublin city becomes the 21st bridge over the River Liffey between Chapelizod and the sea. This bridge will cater to all traffic except private cars, eventually carrying the southbound Luas linkup.
Like the Rosie Hackett, some bridges are for public transport only. Mick Kinahan of the Inland Waterways Association explains the Liffey Viaduct is a railway bridge for the rail line that goes under the Phoenix Park, emerging at Cabra.
Seán Heuston Bridge underwent refurbishment in 2004,
There's no more traffic on it now, except the Luas, the Red Line that goes out to Tallaght.
Under Seán Heuston Bridge is the Frank Sherwin Bridge built in 1982 to alleviate the traffic going over Heuston Bridge. The Millennium Bridge is one of three to cater for pedestrians only, while the most famous, O'Connell Bridge, manages four lanes of cars.
While bridges provide a valuable crossing point,
Sometimes they can encroach too much, and you could very easily turn the river into a tunnel.
Almost half of the 21 bridges were originally built in the nineteenth century. Five of them, nearly a quarter, were built since 1999.
Most of the bridges were renamed following Independence with several of them, like the Rory O'Moore Bridge and Mellows Bridge honouring patriots. The more modern bridges, such as the James Joyce Bridge and the Sean O'Casey Bridge have tended to honour writers. The Rosie Hackett Bridge is the first Liffey bridge to be named after a woman.
