Akashi Kaikyo Bridge is a sea-crossing passage connecting Kobe City and Awaji Island in Hyogo Prefecture, Japan. It is an important bridge on the Kobe-Awaji-Naruto route. Akashi Kaikyo Bridge started construction in May 1988; it opened to traffic on April 5, 1998.
The Akashi Strait separates Osaka Bay from Harima Nada. In ancient times, people took boats from the west to enter Yamato, the center of politics, economy, and culture at that time, so the Akashi Strait is also known as the Akashi Gate. Even in modern times, the Akashi Strait is a major transportation route. With the development of society and technology, the voice of building a bridge here is getting louder.
The Akashi Strait is an international waterway. About 4,000 large ships pass through it every day. The tidal current is extremely fast, with a maximum height of 4.5 m/s, which adds a lot of difficulty to the project. With a total investment of about 4.3 billion US dollars, numerous engineers and architects collaborated to successfully build the world's longest suspension bridge in innovative ways.
Description of the Akashi Kaikyo Bridge Size
The Akashi Kaikyo Bridge is mainly composed of the main girder, two bridge towers, cables, anchorages, approach bridges, and their respective interchange ramps. The entire bridge section is arranged in the southwest to northeast direction. In order to create a good nighttime landscape around the Bridge, Akashi Kaikyo Bridge is equipped with night lighting settings for the main tower, main cable, stiffening truss, and anchorage of the Bridge. The Bridge has approximately 1,800 lights used for national holidays and other events, creating a dazzling light show that can be seen from across the bay.
The Akashi Kaikyo Bridge replaces the ferry service necessary to cross the Akashi Strait, which is highly vulnerable to the frequent storms that plague the strait. The BridgeBridge applies some of the best architectural design and technology across the three spans. It has been designed to withstand earthquakes and harsh sea conditions.
Length and Height of the Akashi Kaikyo Bridge
Akashi Kaikyo Bridge has a total length of 3911 meters and a span of 1991 meters. It is the longest-span suspension bridge in the world. The Bridge has three spans; the two other sections are each 960 meters. The Akashi Kaikyo Bridge is 3,911 meters long overall. The main tower is 297 meters high. The Bridge is a two-way six-lane expressway with a speed limit. The maximum speed limit of the vehicle is 80 kilometers per hour, and the minimum is 50 kilometers per hour.

In May 1988, the bridge construction across the Akashi Strait began after years of geographical and geological research by the Japanese government and experts. The Akashi Kaikyo Bridge has become a major artery connecting the Honshu and Shikoku regions of Japan and has become a part of the national highway network in Japan. The technology and scale of bridge-building are world-class. It is also a famous attraction with a lookout at the top of the tower. Under the bridge on the Kobe side, people can enter the sea promenade and admire the interior of this magnificent bridge and views of the Akashi Strait and Osaka Bay.
