Originally designed and built by James Gandon, O'Connell Bridge was built in 1794-98 and named aftyer the then Viceroy - Lord Carlisle. The original bridge had a hump and was much narrower and Gandon had designed obelisks and plinths for the four corners. In 1880 it was widened and the hump removed - it is now almost square - being as wide as it is long. Because of these works, O'Connell Bridge is unique in Europe as the only traffic bridge as wide as it is long. In 1882 it was renamed after Daniel O'Connell when the statue in his honour was unveiled. Recently the lamps that graced the central island have been restored to their five lantern glory. -- Text from ireland.archiseek.com/buildings_ireland/dublin/bridges/oc... and Wikipedia.
