Incheon bridge, South Korea

Incheon bridge, the world’s fifth longest cable-stayed bridge.

Stretching over 12km from mainland South Korea to Yeongjong Island, the £1 billion Incheon Bridge is the longest in the country, and  the world’s fifth longest cable-stayed bridge. Its cable-stayed section is 800m long with a 230m supporting tower, and is designed to withstand seismic activity, hurricanes and impact from 100,000 tonne ships.

The bridge, which carries a six-lane motorway, is primarily intended to link the booming New Songdo City in the mainland’s Incheon free economic zone with Incheon International Airport – built on reclaimed land connecting Yeongjong and Yongu islands.
