Nestled between the cliffs of southwest China, an engineering colossus is preparing to open its doors – or rather, its roadway – to the world. This is the Huajiang Grand Canyon Bridge, an imposing suspension structure that technically already holds the title of the highest bridge on the planet, with its deck suspended 625 meters – more than double the height of the Eiffel Tower – over the Beipan River in Guizhou province.

This engineering colossus will not only break records for its dizzying height, but will also transform connectivity in a region traditionally isolated by its complex geography.

Final tests completed successfully

Although it is not yet operational, final load tests have been successfully completed, paving the way for its opening to traffic scheduled for autumn of this year, between September and October, according to various sources.

During five days of tests, 96 trucks loaded with a total of more than 3,300 tons crossed the bridge to simulate different traffic scenarios, from heavy flows to braking and changing lanes. speed.

The objective was to test its behavior under real-life conditions. Strategically placed sensors constantly monitored the structure's stress, vibrations, and deformations.

Beyond its impressive height, the bridge represents a milestone in modern civil engineering. According to Xinhua, it has a total span of 2,890 meters and a main span of 1,420 meters, while its tallest tower rises 332 meters, according to Newsweek. These dimensions position it not only as the tallest, but also among the longest suspension bridges on the planet.

Regional transformation and record-breaking construction

However, the work transcends mere technical boasting to become a driver of regional transformation. According to Newsweek, the bridge will drastically reduce travel time between the towns of Liuzhi and Xifeng: from five hours to just one.

And what once required a one-hour traverse through the rugged canyon will now be a scenic drive in just 90 seconds, according to IFL Science.

The speed of construction has also broken records. Started in 2022, the project has progressed at a pace that surprises international experts. Professor Mamdouh El-Badry of the University of Calgary told Newsweek that "in other parts of the world, a project of this magnitude typically takes five to ten years to complete."

Tourist attraction and Guinness record

The bridge will not be limited to being a transportation route. According to IFL Science, once opened, it will have a glass walkway and offer activities such as bungee jumping and paragliding. Its exceptional height will allow visitors to drive, walk, or even jump among the clouds, high above the Beipan River.

Although it holds the title of the tallest bridge in the world based on the distance from its deck to the ground, according to the criteria of the Guinness Book of World Records, it is worth clarifying that this record refers to the free height under the roadway. Currently, that recognition is held by the Beipanjiang (Duge) Bridge in China, at 565.4 meters, until the Huajiang Bridge surpasses it at 625 meters. It should not be confused with the record for the tallest structural bridge, which is measured by the height of its pylons or towers, a title held since 2004 by the Millau Viaduct in France, at 336 meters.
