What is the world s oldest bridge and the largest bridge in the world

The earliest and oldest surviving bridge in the world is the Zhaozhou Bridge dating back 1,400 years.

Zhaozhou Bridge, also known as Anji Bridge.

Commonly known as Dashiqiao, it is on the Huhe River in the south of Zhao County, Hebei Province, only 45 kilometers away from Shijiazhuang City, and is a national key cultural relics protection unit.

The Zhaozhou Bridge was built by Emperor Kaihuang of the Sui Dynasty.

In the last years, it has a history of 1400 years, which was built by Li Chun, an outstanding craftsman of the Sui Dynasty, and many stonemasons, and it is also the first single-hole open-shoulder stone arch bridge in the history of the world. The bridge is full of meters long and wide, and this open-shouldered design not only reduces the resistance of the water flow, but also reduces the weight of the bridge body, and the bridge shape is ethereal and beautiful, and the idea is ingenious, which can be called a unique step through the ages. The railings and pillars on both sides of the bridge are all fine carvings of the Sui Dynasty.

Zhaozhou Bridge integrates technology and art, can be described as "thousands of cars and horses pass, Qiankun this bridge", attracting the literati of the past dynasties to compete for inscriptions, among which Tang Kaiyuan thirteen years, the Ministry of Industry Zhang Jiazhen's "Stone Bridge Inscription Preface" is an important historical document for the study of the big stone bridge. In October 1991, Zhaozhou Bridge was selected by the American Society of Civil Engineering as the 12th International Historic Civil Engineering Milestone and was marked.

What is the largest bridge in the world, do you know? I know let me tell you!

One of the largest bridges in the world – the Danquint BridgeAn introduction to the Danquent BridgeDankunte Bridge is located in the Jiangsu section of the Beijing-Shanghai high-speed railway, starting from Danyang, passing through Changzhou, Wuxi, Suzhou, and ending in Kunshan. The total length of kilometers is more than four times that of the world's longest bridge, the Lake Pontchartrain Bridge in the United States, which is currently recorded in the Guinness Book of World Records.

Due to geological reasons and for the sake of saving land, the bridge is all viaducted. The southern Jiangsu area that the bridge runs through belongs to the plain river network landform, and there are more than 150 rivers with a water surface width of more than 20 meters. Due to its location in an economically developed area and the vertical and horizontal road network, the bridge needs to cross more than 180 roads of various types.

Across highways, railways, and waterways, the Dankunte Bridge spans the entire land of southern Jiangsu with the proud attitude of a modern high-speed railway bridge.

According to the plan, the Dankunte Bridge will be built in Changzhou, Wuxi, Suzhou, Kunshan and other elevated stations, and these cities are also strung together like pearls. Since ancient times, southern Jiangsu, which has been the land of fish and rice, is an extremely active economic growth point, especially the three cities of "Suzhou, Xichang", with a total area of the country, a population of 17%, and an import and export volume of 17%, ranking fourth in the country in terms of GDP. For southern Jiangsu, which is actively seeking a win-win situation in the "Great Taihu Lake Era", the Dankunt Bridge will open a new channel, which will not only accelerate the integration of resources in the region, but also promote the economic resonance of the entire Yangtze River Delta by virtue of its transportation advantages.

The longest bridge in the world is the Danyang-Kunshan Bridge.

Dankunte Bridge is located in the Jiangsu section of the Beijing-Shanghai high-speed railway, starting from Danyang, passing through Changzhou, Wuxi, Suzhou, and ending in Kunshan. The total length of kilometers is the longest bridge in the world currently recorded in the Guinness Book of World Records – more than four times the length of the Lake Pontchartrain Bridge in the United States. According to Britannica, the bridge connecting Shanghai and Nanjing was opened to traffic in June 2011 as a viaduct for the Beijing-Shanghai high-speed railway.

It takes 2 hours to drive through, with a total investment of 30 billion yuan, making it the longest bridge in the world. It is composed of more than 4,500 900 tons of box girders, the first pile was poured in the cavity state on April 7, 2008, the bridge was completed on May 24, 2009, and the track laying work was completed on November 6, 2010, with more than 10,000 workers paying for 3 years, and it was officially opened for operation with the whole line on June 30, 2011.
