Butt Bridge

The Butt Bridge is a road bridge in Dublin, Ireland which spans the River Liffey and joins Georges Quay to Beresford Place and the north quays at Liberty Hall.

The original bridge on this site was a structural steel swing bridge, designed by Bindon Blood Stoney, opened in 1879 and named after Isaac Butt, leader of the Home Rule movement.The swing section, made of wrought iron and weighing 200 tons, ran on a series of cast spoke wheels and was powered by a steam engine, which was housed on a timber pier on the downstream side of the bridge. The swing action allowed boats to pass and berth in the river as far upstream as Carlisle Bridge.
