FOYLE BRIDGE: FABRICATION AND CONSTRUCTION OF THE MAIN SPANS

This is the second of two papers describing the construction of the Foyle Bridge, Londonderry and covers the fabrication, transport to site, and erection of the steel superstructure for the main navigation span and its immediate sidespans. Although the new Foyle Bridge is the largest in Ireland, with a main span of 233.4M, it is not particularly large and the design is not innovative. Engineering interest lies in the ways in which the resources of Northern Ireland were used to best advantage to build the bridge; and in so doing, the bridge steelwork was fabricated by a major shipbuilder, and the erection was by a big lift method. The aims of the paper are to describe briefly the engineering decision-making for the overall scheme and for each of the major operations; to outline the use of the shipyard facilities for the fabrication of 5200 t of steel box girders in only six units; and to indicate some of the problems which arose during the execution of the transport and erection activities.
