What is the longest bridge in the world

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

The Big Danyang-Kunshan Bridge between Shanghai and Nanjing connects through Jiangsu province in China, where it is 164.8 km long and 100 m above ground level, so it is the longest bridge in the world. It should be noted that it runs over the Yangtze River and is topped by the Beijing Shanghai Rapid Railway, traversing rice fields and wetlands, costing 1 billion 8.5.

The longest sea bridge in the world

The Hayuan Quingdao Bridge is the world's longest sea bridge, at 42.5 km in length, connecting the coastal city of Chengdao with its suburb of Huangdao and Hongdao Island on the other side of the Gulf. At least 10,000.00 people were employed to work on its construction, 450,000 tons of steel were consumed and 2.3 million cubic metres of concrete were consumed.

The longest suspension bridge in the world

The Russky Bridge, located over the Eastern Bosphorus Strait to reach Russky Island, is the longest cable-supported bridge in the world. The bridge reached a world record in 2012 because of its dimensions. The central bridge is 1104 metres long and 580 metres long. It is 70 metres above the water level.

The longest cable-supported bridge in the world

The Kaotianmen Bridge is the longest arch bridge in the world, with a total east-west length of 1741 metres, cutting the Yangtze River in the Chongcheng region of China, outperforming the 550-long Bo Bridge in Shanghai since 2003, with a total length of 552 after the completion of its construction in 2009.

The largest bridge in the world

The Milo Bridge is the largest bridge in the world, located over the Tarn Valley on the A75 highway that connects the cities of Paris and Barcelona. The bridge contributed to traffic regulation during the summer months of July and August in the town of Milo, where the area was experiencing a severe traffic crisis before the bridge was built.

The French Highway Administration (SETRA) has studied a series of preliminary proposals for linking the highways of the two hills that limit the valley. Tarn accepted the design of the Milo Bridge, where bridge designer Michel Verlugo made a proposal that included a road that was partially descended from the valley, and then crossed the remaining area of the valley. Tarn has a 700-metre bridge, then reaches a tunnel on the north side of the valley, and then completes its route until the highway reaches.

Both sidewalks and kilns of the bridge were constructed of steel, the pillars were poured out of pre-stressed armed concrete, the bridge became the largest bridge in the world, with a height of 242 metres, a structure of 343 metres, and the bridge tilted from north to south by an estimated 3%, with a curve of 20,000m in diameter.

The highest bridge in the world

The Dugui Bridge of southwestern China is the highest bridge in the world, with a height of 565 metres over the valley below, spanning 1341 metres. It took the Chinese government three years to construct it, costing about $144 million. At this height, it exceeds the record previously recorded as the Seidu River Bridge, which is also in China. The latter rises more than 500 metres above the ground.460 metres, which took three years to establish, cost the French Government $415 million.

The ten longest bridges in the world

Bridges are an important form of construction that humans have known since time immemorial. They were intended to shorten distances and travel times during waterways and valleys.

• Danyang-Kunshan Grand Bridge: The Big Danyang-Kunshan Bridge in China is located on the Beijing Shanghai Expressway, running up to 164,800 metres, and took four years to build, with up to 10,000 contractors, and was terminated in 2010, and the railway operated in 2011, the same year as the Guinness Encyclopedia of World Records.
• (Changhua-Koahsiung Bridge): This bridge is located in Taiwan and is the second longest in the world, with a length of 157,317 metres, the bridge forms part of Taiwan's high-speed rail system and runs along the west coast of the island, and was introduced in January 2007, bringing the number of passengers passing through it to 200 million, only until the first month of 2012.
• The bridge is located in China, and is also followed by high-speed railways between Beijing and Shanghai such as the Danyang-Kunshan Bridge, with a total length of 115,900 metres, and is very strongly designed to make it withstand earthquake pressure.
• Big Tianjin Bridge: The Great Tianjin Bridge, located in China, has a length of 113.62 kilometers and is used as part of China's railway system, and has previously achieved a record in the Guinness Encyclopedia as the second longest bridge in the world.
• (Weinan Weihe Grand Bridge): This bridge, located in China, is the fifth largest in the world, having previously held the title of the largest bridge in the world prior to the construction of modern bridges, reaching 79,732 metres in length, part of the Zhengzhou-xi'an high-speed railway.
• Hong Kong Zhuhai Macau Bridge: The Hong Kong Zhuhai Macau Bridge, located in China, is the sixth longest bridge in the world, with a length of 54,717 metres. The bridge began construction operations in 2009 and was opened in October 2018.
• Bang Na Highway: The Panghna Highway, located in Thailand, was the seventh largest bridge in the world before 2010, with a total length of 54,000m. It forms a high part of the national highway, crossing water only at one point, as most of it is built on land.
• Big Beijing Bridge: The Beijing Grand Bridge, located in China, is part of the 48,163 metre-long Beijing-Shanghai Railway, and has been used as a train highway since 2011.
• Lake Pontchartrain Bridge: The Lake Pontchartrain Bridge in the United States of America is located in the northern direction of New Orleans in Louisiana, and is traveled over Lake Pontchartrain on the outskirts of New Orleans, where the lake was formerly transported by ferry only, and since its opening in 1956 remains the longest bridge in the United States, reaching 38,442 metres in length.
• (Line 1, Wuhan Metro Bridge) is the first line of the underground electric commuter system in the city of Wuhan, central China, with a length of 37,788 metres.

Introduction to bridges

A bridge is defined as an elongated horizontal structure between pillars capable of carrying loads vertically, a simple bridge consists of two beam-bearing pillars, and for the bridge to be free of engineering problems some things must be taken into account during the design, where the braces must be strong enough to carry the structure, the beam between the beams must be strong enough to carry the loads.

Bridges are built from the public funds of the people. They are considered to be in the best interest of the people. The bridge must therefore achieve three important objectives: it must be economic, highly efficient, and a beautiful design. Efficiency is a scientific principle measured through materials reduction and high quality. Economics is a social principle aimed at efficiency at the lowest cost of construction and maintenance.
