Project Details

Elliott Group successfully delivered this technical and complex project involving the construction of a new cable stayed pedestrian footbridge which crosses the existing busy N81 dual carriageway. This development also included the removal of the existing N81 pedestrian bridge and construction of a contemporary new bridge structure linking areas to the North and South of the N81. This presented serious challenges in terms of traffic management and logistics, since the road was kept operational at all times. The new bridge consists of a 25 metre high reinforced concrete pylon which supports a series of composite steel and reinforced concrete deck units. The deck units are carried on a number of cable stays anchored back to the pylon. The construction of the pylon involved considerable temporary works design, to ensure that the reinforced concrete works could be carried out safely. Erection of the suspended deck units and cable stays involved significant traffic management arrangements in order to minimise disruption to traffic during the deck erection operations, with a large proportion of the works undertaken at night.

Additional works included the excavation, piling and construction of the basement adjacent to the N81, construction of internal distribution roads, associated drainage and services. A new junction was also constructed on the N81 to facilitate access to the development. Elliott Group staff expertly managed the construction of this not just the Civils element but the entire project, successfully overcoming the traffic management and logistical challenges on a busy junction in West Dublin.
