The Japanese bridge authority was tasked in 1970 with overseeing a vast project to link to two main islands of Honshu and Shikoku. The project, scheduled for completion in 2000, comprises 18 bridges and more than 186 km of associated roadways that form three separate crossings of the Seto Inland Sea. When completed, Japan will have 6 of the 20 longest spanning bridges in the world. The two crowning achievements of the initiative are the Akashi-Kaikyo and Tatara Bridges. The Akashi-Kaikyo, a suspension bridge with a main span of 1,991 m scheduled for completion in 1998, will be the longest-spanning bridge in the world. The Tatara cable-stayed bridge will take its place as the longest bridge of that type when completed in 1999.
