The original bridge on this site was a structural steel swivel bridge, which was opened in 1879 and named for Isaac Butt, leader of the Home Rule movement (who died that year).
It was overshadowed by a number of other organisations; from the Irish Republican Brotherhood and Isaac Butt's Home Government Association, a precursor of his later Home Rule League, to the Liberal and Conservative parties.
