A key infrastructural link for the south east will form the focal point of the New Ross bypass. The Rose Fitzgerald Kennedy Bridge is a three tower 887m long extrados bridge, the longest of its type in the world.
Extending more than 300m over the River Barrow and with a 36 metre clearance the bridge is a key link for the surrounding communities and also for shipping navigation to the port of New Ross.
Extrados bridges are noted for their lower tower heights when compared with conventional cable stayed bridges. While aesthetically pleasing such an approach puts additional demands on the materials that make up the bridge with higher strength concretes typically required.
This has resulted in the use of high strength concrete mixes including C50/60, C60/75 and C80/95. While the use of C50/60 concrete is relatively common, the use of C60/75 and in particular C80/95 concretes in Ireland is rare, and seldom has such concrete been used to the scale required for this bridge.
