A feat of engineering in a challenging land.
With an area of over 176,000 km², Guizhou province in southwestern China is one of the country's most rugged and mountainous regions. Known for its deep canyons and inaccessible terrain, Guizhou has long faced numerous challenges in developing its transportation infrastructure. To address this, China has decided to build an ambitious infrastructure project – the Huajiang Grand Canyon Bridge, the world's tallest bridge, scheduled to open in June 2025.
Huajiang Grand Canyon Bridge
Impressive specifications
The Huajiang Deep Gorge Bridge has a total length of 2,890 meters, with a main span of 1,420 meters, allowing it to cross the deep gorge of the Beipan River. Remarkably, the bridge reaches a height of 625 meters, equivalent to the height of a 200-story building. This allows it to traverse the deep gorge and create a unique and impressive viewpoint for both tourists and those wishing to witness this remarkable feat.
As a suspension bridge, the main piers are 262 meters high and constructed of steel, with a total steel weight of up to 22,000 tons – equivalent to the weight of three Eiffel Towers. The Huajiang Deep Gorge Bridge is designed to withstand harsh natural elements, from strong winds to earthquakes, and will be the most reliable bridge in the mountainous region of Guizhou.
The world's tallest bridge is expected to open in June 2025.
Challenges during the construction process
The construction of the Huajiang Deep Gorge Bridge was no easy task. Engineers and workers faced significant challenges throughout the construction process. The rugged terrain and harsh climatic conditions created numerous difficulties. To complete the bridge, thousands of tons of materials and heavy equipment had to be transported to the construction site via rough, mountainous roads.
Furthermore, modern technologies were applied during construction, including the use of high-strength steel structures, durable cable systems, and methods for testing material strength through simulations. As a result, the bridge not only met the requirements for height and length but also withstood the harshest natural conditions of the region.

Economic and social impacts on the region
One of the key reasons China was determined to build the Huajiang Deep Gorge Bridge was its potential to boost the economy and improve the quality of life for local residents. Before the bridge was built, traveling between the Liuzhi and Anlong areas was a major challenge for people and vehicles. The journey across the gorge took up to two hours, making the transportation of goods and tourism difficult.
When the Huajiang Deep Gorge Bridge is completed, travel time will be reduced to approximately one minute. This will not only enhance connectivity between regions but also create opportunities for tourism, trade, and investment development. Tourists will be able to easily access Guizhou's interesting destinations, while businesses will also benefit from reduced transportation costs and increased trade.
Furthermore, the bridge will help promote the development of other industries, including ecotourism. Guizhou is known for its magnificent natural landscapes such as canyons, waterfalls, and nature reserves. The Huajiang Deep Gorge Bridge will open up new opportunities for tourists to explore the region.

The Huajiang Deep Gorge Bridge is not only a crucial transportation project but also a symbol of China's infrastructure and construction prowess. With a series of large-scale infrastructure projects underway across the country, from sea bridges to high-speed rail lines, China has established itself as a leading nation in the construction sector. Once completed and operational, the bridge will be a vital part of China's infrastructure development strategy, attracting tourists and engineering experts worldwide.
