The Ha'penny Bridge (Irish: Droichead na Leathphingine), is a cast-iron pedestrian bridge which was built in 1816 over the River Liffey in Dublin, Ireland. Originally it was named the Wellington Bridge (after the Duke of Wellington), which was later changed to the Liffey Bridge, its official name to this day though it is commonly referred to as the Ha'penny Bridge, named after the toll which was in effect until 1919 when it was finally dropped. The toll was given to a man called William Walsh who decided to build the bridge rather than continuing with his ferry service to transport people across the swift moving river. He was granted the right to 100 years of tolls.
