The Ha’penny Bridge, known later for a time as the Penny Ha’penny Bridge, and officially the Liffey Bridge, is a pedestrian bridge built in May 1816 over the River Liffey in Dublin, Ireland. Made of cast iron, the bridge was cast at Coalbrookdale in Shropshire, England.
Before the Ha’penny Bridge was built there were seven ferries, operated by a William Walsh, across the Liffey. The ferries were in a bad condition and Walsh was informed that he had to either fix them or build a bridge. Walsh chose the latter option and was granted the right to extract a ha’penny toll from anyone crossing it for 100 years.
On 19 May 2016, the bicentenary of the bridge was celebrated with a symbolic procession over the bridge involving the current Lord Mayor, Críona Ní Dhálaigh, descendants of J.C. Beresford and of John Windsor from England.
