The new Dillon Bridge, named after John Dillon is a road bridge crossing the River Suir, built c. 1880, it was reconstructed and widened in 1975.

John Dillon (4 September 1851 – 4 August 1927) was an Irish politician from Dublin, who served as a Member of Parliament (MP) for over 35 years and was the last leader of the Irish Parliamentary Party.
