N25 New Ross Bypass
The Rose Fitzgerald Kennedy Bridge (887 m long) is the most iconic element of the N25 New Ross Bypass project in southern Ireland. The bridge is a hybrid structural solution between a box girder bridge and a cable-stayed bridge. The stay cable system was validated with specific testing to the Chicago Testing Laboratory and Michigan State University. These tests confirmed the cable system’s endurance, efficiency, and durability. The project has an important social impact improving regional mobility and supports economic growth. The final structure provides an elegant and slender visual profile while handling the high loads of long-span extradosed design.
