This cable-stayed arch bridge is one of a set of distinctive new structures in Putrajaya city. The bridge is a provocative contribution to the debate on tenable standpoints concerning bridge concepts. It is a combination of two bridge types and was a challenge to the construction engineers during the erection stages. A sophisticated load transferring procedure combined with an initial monitoring period and subsequent fine tuning of the hangers and stay cables lead to a well-balanced load distribution considering all thermal effects and service load stages. The structure is a combination of two overhead inclined arches and a 'classical' twin-pylon cable stayed bridge. The main span is 300 m and the sword shaped pylons are 73 m high. The centre spine of the 32 m wide deck is suspended to a uni-planar stay cable arrangement, its wings are supported by the arch hangers.The arches are made of cold rolled steel tubes (2,20 m in diameter), erected on temporary scaffolding towers and welded on site.
