Where is the longest suspension bridge in the world?

Japan's Akashi Kaikyo Bridge, completed in 1998, is the largest suspension bridge in the world, with a span of 960m+ and a high main tower; The main cable diameter year completed Japan Tatara Bridge is the world's largest steel cable-stayed bridge, span length 270m + 890m + 320m, the main tower is a diamond-shaped steel tower, the tower is 220m, the whole bridge 168 cable-stayed cables. At the beginning of the 21st century, many countries are planning ultra-long span bridges, such as the Gibraltar Strait Bridge in Spain and Morocco, with a main span of 5,000m. In the Tsugaru Strait of Japan, the main span of the bridge is about 4,000 meters long, and the technical problem has been solved.

As the most dazzling pearl on the first ring road of Foshan——— known as the world's first span single-tower single-span four-cable surface self-anchored suspension bridge ——— the main tower saddle of Pingsheng Bridge was successfully completed on the 24th.

Located in Pingzhou, South China Sea, Pingsheng Bridge connects Shunde District across the Dongping Waterway, and is an important transportation hub in the Guangzhou-Foshan Economic Circle under construction and a landmark project on the First Ring Road of Foshan under construction. The main bridge of the bridge is meters long, the main span is 350 meters, the main tower is 142 meters high, the height is equivalent to more than 40 floors, the total cost is 100 million yuan, due to the characteristics of large span, it has become the world's largest single-tower four-cable surface self-anchored suspension bridge.

Akashi Kaikyo Bridge, Japan.

Completed in 1998, the Akashi Kaikyo Bridge in Japan is the largest suspension bridge in the world.

On April 5, 1998, the world's longest suspension bridge, the Akashi Kaikyo Bridge in Japan, was officially opened to traffic. The bridge is located between Kobe City and Awaji Island in Japan (135 degrees 01 minutes east longitude, 34 degrees 36 minutes north latitude), with a total length of 3,911 meters and a main pier span of 1,991 meters. The two main piers are 297 meters above sea level, the foundation diameter is 80 meters, and the water section is 60 meters high.

The two main steel cables are about 4,000 meters each, with a diameter of meters, and are composed of 290 thin steel cables and weigh about 50,000 tons. Construction of the bridge began in May 1988. It was completed in March 1998.

For the first time, the Akashi Kaikyo Bridge uses 1800MPa ultra-high-strength steel wire, which reduces the diameter of the main cable and simplifies the connection structure, and is the first suspension bridge main cable, which is also the first cross-valley suspension bridge constructed by the jacking method, which was built by the French Eiffel Group Company.

The world's most famous suspension bridges are as follows:

The largest chain bridge in the world is the Akashi Kaikyo Bridge.

The Akashi Kaikyo Bridge is a sea crossing connecting Kobe City and Awaji Island in Hyogo Prefecture, Japan, and is an important bridge on the Kobe-Awaji-Naruto route. Construction of the Akashi Kaikyo Bridge began in May 1988. On September 18, 1996, the main bridge closure project was completed, and the bridge was completed in its entirety; It was put into operation on April 5, 1998. The Akashi Kaikyo Bridge has a total length of 3,910 meters, and the main bridge is 1,990 meters long; The bridge deck is a two-way six-lane highway with a design speed of 100 kilometers, making it the largest chain bridge in the world.

The Akashi Hail Tsukyo Bridge is mainly composed of the main girder, two pylons, cables, anchor blocks, approach bridges and their various interchange ramps, and the entire bridge section is arranged in the direction of southwest to east and north. In order to create a good nighttime view around the bridge, the main tower, main cable, stiffener truss, and anchor block of the Akashi Kaikyo Bridge are illuminated at night, and LED lights are installed on the main cable, so that the bridge changes in color over time.

The main span of the world is a long chain bridge

The world's earliest chain bridge is Ji Hongqiao, built in 1295, the first wooden bridge, to the Ming Dynasty Chenghua period before it was rebuilt into a chain bridge, all dynasties have repaired or rebuilt this bridge, to 1681 when the bridge pier and bridge fort were built on this bridge. Jihongqiao is the only way to develop the southwest in the past dynasties, and its geographical location is of great significance.

The world's first chain bridge is.

Ji Hongqiao is located on the Lancang River at the junction of Baoshan City and Yongping County in Yunnan Province, is an iron cable bridge erected on the cliff, the total length of the meter, the width of the meter, mainly composed of 18 iron locks, the bridge plate is paved on the top, the two piers are built with the quaint bridge fort, named "Wuhou Temple" and "Guanyin Temple" respectively.

As early as the Yongping period of the Eastern Han Dynasty, the local recruited a large number of migrant workers to build a bridge on the Lancang River, and finally a rattan bridge across both banks, like a rainbow that appeared after the rain on both sides, this is also the origin of its name, although it caused a deep suffering to the enslaved migrant workers when building the bridge, but its historical significance is also very significant.

Many literati have been to Jihongqiao

Throughout the ages, Ji Hongqiao has been repaired or rebuilt many times, there are literati here to play and appreciate in all dynasties, there are words such as "the first bridge in the southwest" and "cliff crossing" carved by literati and ink writers on the west cliff, Xu Xiake, a famous geographer in our country, has also been to this bridge.
