The Bridge
On South Korea’s southern coast is the industrial area of Yeosu. It is connected to the mainland by one of the world’s longest-span suspension bridges, the Yi Sun-sin Bridge. The large container ships that navigate the waterway require a very high clearance to ensure safe passage so the deck is 80m above sea level.
The 6m-wide steel girder deck is a streamlined twin-box with diaphragms that was developed by Yooshin Corporation from Bill Brown’s design innovation of the 1990s. It provides an aerodynamically-stable deck for the long clear span of 1,545m and total length of 2,260m.
