The Longest Bridge in the World – History
Before the bridge was made, the passengers used ferries to cross the Asahi Strait. This waterway was dangerous, especially during storms. The storms in this area can be very aggressive. In 1955, a couple of ferries sank because of storms. 168 people got killed in these accidents. Japanese government had to do something to solve this problem and prevent future accidents. However, the construction works began in 1986, and the Pearl Bridge was finally opened in 1998. This was the best way to make the traffic safer and faster. This strait is one of the international waterways, and it has to be safe.
The Pearl Bridge has 3 spans. The bridge is designed to stand very strong wind, earthquakes and sea currents. It has two supporting towers that are nearly 299 meters above the sea. More than 350 000 tons of concrete were needed for each anchorage. 300 000 kilometers of steel cables were used.
The Pearl Bridge has 1737 lights. 115 lights are used for main towers, 1084 are used for cables, 132 lights are used for anchorages and 405 illuminations lights are used for girders. The bridge looks beautiful, especially when the lights are on. Various combinations are used for illumination. During the national holidays, different light patterns are used.
