China Set to Open World’s Tallest Bridge in Guizhou by Mid-2025

China is preparing to unveil the world’s tallest bridge this June — the Huajiang Grand Canyon Bridge — a towering feat that will soon redefine global infrastructure benchmarks.

Soaring 2,051 feet (625 meters) above the river level in the mountainous province of Guizhou, the bridge surpasses France’s Millau Viaduct by an astonishing 947 feet, making it the tallest bridge on the planet upon completion.

Located in southwest China, the Huajiang Grand Canyon — often referred to as the “earth crack” — presents a dramatic natural obstacle, now conquered by modern engineering. The bridge’s location in Guizhou, a region known for its rugged terrain and economic challenges, makes the project not only record-breaking but also transformational for local transportation and connectivity.

Spanning a total length of 9,482 feet (2,890 meters), the steel truss suspension bridge began construction on January 18, 2022, and is scheduled for full completion by June 30, 2025. According to local media and project officials, construction has already reached 95% completion, with plans to open the bridge to traffic in the second half of the year.

“This super project that spans the ‘earth crack’ will be the world’s first of its kind in both directions,” said Zhang Shenglin, Chief Engineer of the Guizhou Highway Group. “It will stand as another landmark showcasing China’s strength in infrastructure development.”

One of the bridge’s most impactful benefits will be the drastic reduction in travel time across the canyon — from two hours to just one minute — significantly easing transportation for residents and boosting economic activity in the region.

The bridge’s massive structure is supported by steel trusses weighing approximately 22,000 tons — the equivalent of three Eiffel Towers. It will become a key part of China’s continued effort to enhance infrastructure in its more remote regions.

Currently, nearly half of the world’s tallest 100 bridges are located in Guizhou, solidifying the province’s growing reputation as a hub of engineering marvels. With the Huajiang Grand Canyon Bridge soon to take its place at the top, China once again cements its position as a global leader in infrastructure innovation.
