The Kwang Ahn Bridges, Pusan

The Kwang Ahn bridges form a 7.42 km long highway bridge system, comprising a suspension bridge, continuous 120 m span truss bridges, and continuous 60 m span steel box girder bridges. The bridge has 18 wide twin decks providing 4 traffic lanes in each direction. The construction site is located in front of the beach, and the average depth of the sea is about 12 m. The design criteria are as follows: a maximum wave height of 10.8 m, a maximum velocity of the tidal current of 0.4 m/s, a tidal range of less than 1 m, and a wind velocity of 45 m/s. When the bridge system opens to the public around September 2002, more than 60,000 vehicles per day are expected.
