The River Liffey flows through Dublin and has twenty four bridges. The most iconic bridge is the Halfpenny Bridge, built in 1816, which is a pedestrian only bridge and customers were charges half a penny to cross it when it first opened. The O’Connell bridge was built in 1791. The Samuel Beckett bridge which was built in 2009 and designed by Santiago Calatrava links both sides of docklands including the financial quarter.
