The Ha’penny Bridge (Irish: Droichead na Leathphingine or Droichead na Life ), known later for a time as the Penny Ha’penny Bridge , and officially the Liffey Bridge , is a gångbrobyggdes May 1816 over the River Liffey in Dublin, Ireland.   Made of cast iron bridge was cast at Coalbrookdale in Shropshire, England. 
Originally called the Wellington Bridge (after the Dublin-born Duke of Wellington), the name of the bridge changed to Liffey Bridge . The Liffey Bridge (Irish: Droichead na Life )  remains the bridge’s official name to this day, although it is usually called the Ha’penny Bridge.
Before Ha’penny Bridge was built, there were seven ferries, operated by William Walsh, of the Liffey.  The ferries were in poor condition and Walsh was informed that he had to either fix them or build a bridge. Walsh chose the latter option and got right to extract a Ha’penny toll from someone passes for 100 years. 
Initially, the toll was not based on the cost of construction, but to match the fees charged by the ferries it replaced. A further condition for the design was that if the citizens of Dublin and found the bridge toll to be “objectionable” in its first year, it was removed at no cost to the city. 
The toll was increased over a period of time to a penny-Ha’penny (1 ½ pence), but finally fell in the 1919th While the figure was in operation, there were turnstiles at either end of the bridge.
The production of the bridge on behalf of the then mayor Dublin, John Claudius Beresford with the Coalbrookdale Company in England, which threw the ribs of the bridge in 18 sections, then transported it to Dublin. The design and erection was supervised by John Windsor, one of the company managers and a pattern maker. 
Renovation and maintenance
In 2001, the number of pedestrians who use the bridge daily was 27,000 and given these traffic levels, a structural survey showed that the renovation was required.  The bridge was closed for repairs and renovations during 2001 and reopened in December 2001  sporting their original white color.
The structure was built to retain many of its old components, although controversial, some features removed. Repair work has been carried out by Harland and Wolff. 
In 2012, with reference to the maintenance and the risk of injury, Dublin City Council removed a number of love turned from Ha’penny Bridge and nearby Millennium Bridge, and asked people not to add any more.  In 2013 the Council removed over 300 kg locks from the bridge and signs were asking people not to put padlocks on the bridge.
