The Akashi-Kaikyo Bridge (Akashi-Kaikyo Ōhashi or 明石 海峡 大桥 in Japanese) is the longest suspension bridge in the world. It is 282.8 meters high and 3,911 meters long. Its main span is 1,991 meters long well. Opened April 5, 1998, connects the city of Kobe Awaji island of Honshu island. The bridge, in the January 15, 1995 has resisted the Kobe earthquake of intensity 6.8 on the Richter scale. The Two Towers did not suffer extreme damage (although the earthquake has claimed more than 15,000 victims in the country), but the south tower moved to 120 cm, and work resumed only after a month. The Japanese government decided to construct two specific sites to contain the 1:100 scale models of the two towers and submit them to the appropriate tests in the wind tunnel in order to endure. In 1989 they were resting on the seabed at a depth of 70 m two cylinders with a diameter of 70 meters each, and with a double wall that were to form the foundation of the two towers. The cylinders were dropped on a bed of laying the seabed in which had been previously excavated and completed with a ring of the crawl space act to ensure that during the phase of supported there were severe sliding due to the viscosity of the bottom itself.
