The Danyang Kunshan Grand Bridge crosses the largest water body, Yangcheng Lake, covering 5.5 mi (9 km).

The Danyang Kunshan Grand Bridge broke the Guinness World record of being the longest bridge in the world. The Yangtze River is on the south side of the Danyang Kunshan Grand Bridge.

The building of the Danyang Kunshan Grand Bridge has resulted in forming a connection between two famous metropolitan cities. These cities are Nanjing situated in Jiangsu province and Shanghai in China. The low-rise paddies are a portion of the Yangtze River delta through which the grand bridge crosses. The development of the Danyang Kunshan Grand Bridge helped to solve the most concerning problem of railway traffic at that time. It has also helped people travel long distances quickly. The famous foods of China are tangbao, pidu noodles, and sesame pancakes.

The Speed Limit On The Danyang-Kunshan Grand Bridge

The Danyang Kunshan Grand Bridge is the world's longest bridge and is 102.4 mi (164.8 km) long. The speed limit is approximately 51 mph (82 kph) but is not specifically mentioned.

The Danyang Kunshan Bridge is a viaduct bridge. This bridge consists of small stands that is created to cross a gorge. The cities Danyan, Suzhou, Changzhou Wuxi, and Kunshi are also touched by the bridge. The Lake Pontchartrain Causeway in Louisiana is nearly 24 mi (38.6 km) long, making it the world's longest continuous bridge crossing a body of water. The Bang Na Expressway in Thailand, on the other hand, is the world's longest road bridge, stretching 34 mi (54.7 km). The Danyang-Kunshan Grand Bridge name seems a little much at times, however for this bridge, the 'Grand Bridge' appears to be a well-deserved term.

The construction of the Danyang Kunshan Bridge has immensely reduced the journey from Ningbo to Jiaxing. It sorted the problem of traffic, and people can travel between the two cities in just two hours. This journey previously took four and a half hours to travel. China has gained the reputation of implementing major engineering projects.

Design Facts On The Danyang Kunshan Grand Bridge

Some of the basic design facts about the Danyang Kunshan Grand Bridge are discussed below.

The bridge was built at an astounding cost of $8.5 billion. The Yangcheng Lake section of the bridge is supported by 9500 concrete pilings and contains 450,000 tons (408,233,133 kg) of steel. Steel cables were used in large amounts to support the construction of the Grand Bridge. The structure was built to withstand extreme weather and direct hits from navy vessels weighing up to 300,000 tons (2,721,554,22 kg).

The Langfang-Qingxian viaduct, a part of the bridge, is 70.8 miles (114 km) long, making it the world's second-longest bridge. We only know that the bridge is the world's longest bridge in the world but the designer behind it is not known. A recent investigation revealed that the China Road and Bridge Corporation had something to do with the designing of this bridge. This company is funded by the Chinese government and has carried out major civil engineering projects in China. There were so many obstacles present during the development of the bridge like lakes, canals, and the terrain. However, construction was finished in the original four year time span.

The Danyang-Kunshan Bridge had to be adaptable and dynamic as it rose and fell over 62 mi (100 km) of different terrain. Because the vast majority of the land in the river's flood plain is made up of soft soils rather than hard bedrock, it has to be strengthened on a regular basis.

In early 2000 when rail transport was of incredible importance, Chinese companies decided to recreate public transport to build bridges of all possible sizes and shapes. As a result of this bridge-building revolution, more than hundreds of projects were made in the mountainous and terrain areas. After creating so many bridges over time, the Chinese government designed of the most impressive structures, the Danyang Kunshan Grand Bridge. It was designed to connect Shanghai city to the capital of East China's Jiangsu province. The 100 mi (160.9 km) long bridge had to be built in a way that meant it could go through canals, rivers, lowland rice paddies, lakes, and uneven terrain.

The bridge has a total length of 102.4 miles (164.8 km) with an average height of 100 ft (31 m) from the ground. After completion, it has easily broken the record of all other long bridges. For the major section, the bridge follows the direction of the Yangtze River. The Danyang Kunshan Grand Bridge is the largest bridge in the world and itss rail segment known as Langfang qing xian covers a distance of 70.8 mi (114 km).

Another 5.6 miles (9 km) of the bridge directly follows Yangcheng Lake in Suzhou. This particular section was designed with steel cables, 2000 pillars, and a steel structure of 450,000 tons (408,233,133 kg). The construction of the bridge was done in such a way so that it can tolerate all types of natural disasters including eight magnitude earthquakes and typhoons. Naval vessels also directly influenced the design of the bridge.

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