The Akashi-Kaikyo Bridge also popularly known as the Pearl Bridge, has the longest central span of any suspension bridge. The central span is staggering 1,991 metres (6,532 ft) making it a truly marvelous civil engineer wonder. Located in Japan, Akashi Kaikyo Bridge was completed in 1998 with the purpose of linking the city of Kobe on the mainland of Honsho to Iwaya on Awaji Island by crossing the busy Akashi Strait.
Central span – 1,991 metres (6,532 ft)
Steel – 181,000 tonnes ( It is said that total stell cable used in this bridge could encircle the entire world 7 times.)
Workers – 2 Million
Time- 10 years
Concrete – 1.4 million cubic metres
The bridge is constructed by using two main cables which strech between two towers. The road is supported by other cables which are eventually tied up with main cables. Two large anchor blocks on either end support this gigantic structure.
