Beginning of construction.
"Ulsan Harbor Bridge is the long-span suspension bridge that crosses Tae-Hwa River of Ulsan Metropolitan City in Korea. The bridge was initiated as the part of the main route that connects the eastern and western industrial regions of Ulsan City in order to reduce the cost of transportation, to ensure transportability via Ulsan Bay and boost tourism.
Ulsan Harbor Bridge is one of the biggest bridge projects in Korea. The length of the central span of the bridge is 1,150m. As a single-span suspension bridge, the bridge will be the fourth-longest bridge in the world following Runyang Bridge (1,490m), Jangyin Bridge (1,385m) and Yangluo Bridge (1,280m) when completed.
Many state-of-art technologies including high-performance materials and innovative erection methods are adopted for design and construction of the bridge. The high-strength PPWS cable (TS = 1,960 MPa class), which have been developed recently, are applied for the main cable of the bridge. It is the first application worldwide. Effective equipment is used for erection of the PPWS cables. In order to minimize damage of the environment, the tunnel type anchorage are used as cable anchorages. The stiffened girder is optimized using wind tunnel tests and CFD analysis. The effective ACS is utilized for construction of high-rise pylons to reduce the period of construction.
