China Built The World’s Highest Bridge With A Million-Dollar Investment. Known As The Duge Bridge, This Project Was Considered An “Impossible Feat” By Engineering, Utilizing Innovative Technologies In Its Construction.
Considered a true “impossible feat” of Chinese engineering, the Duge Bridge, also known as Beipanjiang, is the highest bridge in the world, soaring an impressive 565 meters above ground. Check out all the details of this extraordinary engineering work and understand how China managed to build such a monumental structure. We will discuss the technological innovations and challenges overcome to make this architectural wonder a reality.
The Highest Bridge In The World Cost R$ 866 Million
Also known as Duge Bridge, its construction was completed in 2016. It is the first bridge in the world to surpass the 500-meter height barrier. In addition to its record height, the crossing is not the shortest, spanning 720 meters over the Beipan River, between the provinces of Yunnan and Guizhou, in southwestern China.
The construction of the highest bridge in the world in China began in 2013 and cost around R$ 866 million. The bridge was completed on September 10, 2016, and was inaugurated on December 29, 2016. The recognition as the highest bridge in the world came only in 2018, from the Guinness World Records.

Engineers from China spent more than 580 days drilling in the Taklamakan Desert, and the project reached a depth of 10,910 meters, crossed 12 geological layers, reached rocks more than 500 million years old, and faced temperatures and pressures so extreme that the last 910 meters took almost a year to complete.

A new bridge costing up to $2 billion is beginning to redesign the Panama Canal with six lanes, integration for mass transport, and a strategic crossing aimed at alleviating one of the most critical logistical bottlenecks in Central America.

The 634-meter Tokyo Skytree tower became Japan’s tallest antenna by combining a triangular base embedded in mud, 37,000 steel parts, and a pagoda-inspired core that cuts oscillation by up to 50%, keeping 35 million connected even with 1,500 tremors per year.

650 m² of walls erected in a few weeks by a giant printer that deposits concrete layer by layer, Apis Cor’s project in Dubai accelerates structural construction and integrates a plan for 25% of the city’s buildings to use 3D printing by 2030.
The Duge Bridge is part of the Hangzhou-Ruili Expressway (G56) between Qujing and Liupanshui. The eastern tower stands 269 meters tall, being one of the tallest bridge towers in the world. Thus, the highest bridge in the world follows the model of a cable-stayed bridge, like the one located in the Brooklyn neighborhood of São Paulo. This type of structure is made from one or more towers, from which the cables support the bridge.
The Construction Process Of The Duge Bridge
The bridge, with a height equivalent to a 200-story building, is one of three bridges in the Bijie-Duge section of the Hangzhou-Ruili expressway, a road that connects the cities of Hangzhou in Zhejiang province and Ruili in the Dehong Autonomous Region, Yunnan province.
As it was built over a steep canyon with complicated geological conditions, the Duge Bridge created the need for new technologies and construction methods.
The company responsible for the construction of the bridge also completed a research project for the Ministry of Transport of China during its construction.
Furthermore, they received several mentions for the construction project, including four patents for the invention of new world-leading technologies, seven patents for new utility models, a Gold Medal from Gustav Lindenthal, considered the Nobel Prize in the field of bridge construction, and the highest Science and Technology Award from the China Transportation and Highway Society.
China Sets A New Record With Its New 625-Meter Bridge
If the more than 500 meters of the Duge Bridge already seem daunting, the Chinese are thinking bigger. Located in the Great Huajiang Canyon, with a vertical height of 625 meters from the bridge deck to the water surface, the expectation is that the bridge over the Great Huajiang Canyon will become the highest bridge in the world upon its completion in 2025. This will reduce the travel time through the canyon from about an hour to just one minute.
Additionally, China’s engineers are also working on plans for the Yongchang Lancangjiang Bridge in Yunnan. The project will have a height of 610 meters and will be completed later, in 2027.
China also boasts the largest bridge on the planet, which is the Danyang-Kunshan Grand Bridge, a viaduct 164.8 kilometers long that carries high-speed trains between Beijing and Shanghai.
Parabenizo os chineses, doutores em tecnologias de ponta, pelo feito.
