In February 2011 a 200-year-old section of quay wall beside the bridge at Bridge Street collapsed into the river Dodder. The collapse of around 40 metres of the wing wall on Fitzwilliam Quay happened early in the morning following high tide on the river. The reconstruction consisted of building approximately 50m of quay wall and tying-in the new masonry to the bridge at the junction of Bridge Street. As 26m of the original quay wall had collapsed into the tidal reaches of the river, it was necessary to remove all remaining elements prior to construction. The services in the location also had to be removed before being replaced with new chambers and ducts
