Description
A plaque beside the Sean O'Casey Bridge provides the passerby with a good introduction to its history. In 2002 the Dublin Docklands Development Authority held an International Competition for the design of a new pedestrian bridge, capable of opening, across the River Liffey in Dublin. The consulting engineering company, O'Connor Sutton Cronin, entered a joint bid for the bridge. They point out that the width of the river crossing at this point is approximately 100m and, " .. the competition requirements for maximizing head room and an opening bridge to accommodate marine navigation were some of the key structural design criteria which led to a solution comprising two leaves of an opening swing bridge." The architects, Brian O’Halloran & Associates, say on their website that, "We propose a symetrical bridge of twinned cantilevered cradles suggesting a formal maritime gateway to the city. The double swing opening sequence of the structure will be an appropriate event to compliment the arrival of sea craft into the heart of Dublin."
