World's longest suspension bridge — In 1955, two ferries sank along the Akashi Strait in Japan, killing 168 children. The tragedy led to 30 years of research to design a bridge that would link Awaji Island to Kobe. The bridge would need to be able to withstand severe earthquakes and typhoons. In 1988, Japan began construction of the world's longest, highest and most expensive suspension bridge. This episode presents a stage by stage look at the construction of the bridge, and the obstacles faced in its construction, including the Kobe earthquake in 1995. (thetvdb.com)
