The 1.7km-long, dual two-lane bridge joins the cities of Masan and Changwon in the southern part of Korea. It provides a vital link across Masan Bay to relieve traffic congestion and shorten commuting time. Arup provided specialist technical and construction support services for the project.
The project features a 740m, cable-stayed bridge with a main span of 400m, side spans of 175m and two 164m-high, H-shaped pylons. The bridge deck is composite, consisting of concrete slab on steel plate girders. Stay cables of the parallel wire system were fabricated by Shanghai Pujiang Cable Company in China. The cable-stayed bridge also has VSL mono-strand cables inside the end piers that function as a tie-down system. This transfers the negative reaction at the ends of the side spans to pre-stressing tendons and the concrete in pier shafts and pile caps.
The bridge opened to traffic in July 2008, shortening the commute between the twin cities by 30 minutes.
