World’s Highest Bridge Opens in China With a Spectacular Waterfall Curtain

The world’s highest bridge, the Huajiang Grand Canyon Bridge in Guizhou, China, officially opened to traffic on September 28, 2025. Rising 625 meters (2,051 feet) above the Beipan River, this steel truss suspension bridge surpassed China’s own previous record-holder and introduced a striking artificial waterfall curtain as part of a purpose-built tourism experience.

What Is the Huajiang Grand Canyon Bridge?

The Huajiang Grand Canyon Bridge is a steel truss suspension bridge spanning the Huajiang Canyon in Guizhou Province, southwest China. It crosses a gorge so deep and narrow that locals call it the “Earth’s Crack.” With a total length of 2,890 meters and a main span of 1,420 meters, it holds two world records simultaneously: the highest bridge of world and the longest-span bridge built in mountainous terrain.

Construction began in January 2022 and wrapped up in just three years and eight months, an exceptionally fast timeline for a project of this scale. The bridge now carries the Guizhou S57 Liuzhi-Anlong Expressway, connecting Liuzhi Special District to Anlong County and transforming cross-canyon travel from a two-hour drive to a journey of about two minutes.

Breaking China’s Own Record: The Previous Highest Bridge in the World

Before September 2025, the title of highest bridge in the world belonged to the Beipanjiang Bridge, also known as the Duge Bridge, located approximately 200 kilometers away in the same Guizhou province. That bridge stood 565 meters above the Beipan River when it opened in 2016. The Huajiang Grand Canyon Bridge clears it by roughly 60 meters, making China the only country to have held this record multiple times in succession.

For context, the entire Empire State Building could fit beneath the Huajiang bridge deck with around 180 meters to spare. The bridge is nearly nine times as tall as San Francisco’s Golden Gate Bridge and more than twice the height of the Royal Gorge Bridge in Colorado, the highest bridge in the United States at 291 meters above the Arkansas River.

According to the website HighestBridges.com, all 18 of the world’s tallest bridges have been built or are currently under construction in China. Of the world’s 50 bridges exceeding 300 meters in height, only three are located outside China. Guizhou province alone hosts nearly half of the world’s 100 highest bridges, with more than 32,000 bridges either completed or in development across the province.

Engineering Challenges: Building at 625 Meters Above the Canyon Floor

The Huajiang Grand Canyon presented some of the most difficult construction conditions engineers had encountered. The karst terrain features steep canyon walls, altitude differentials of nearly 1,000 meters across the site, and powerful unpredictable winds that made cable laying and steelwork at extreme heights particularly dangerous.

Engineers needed the bridge deck at an elevation of at least 1,100 meters above sea level, leaving no option except to span the entire 625-meter-deep gap with a single suspension crossing of epic scale. The north tower stands 262 meters tall due to the steep canyon slope on that side, while the south tower reaches 205 meters. Together they support a main span of 1,420 meters, ten meters longer than the Humber Bridge in the UK, which held the world’s longest suspension span record for 17 years.

To achieve millimeter-level precision hundreds of meters above the canyon floor, the construction team used China’s BeiDou Navigation Satellite System, drone-guided operations, BIM modeling, and intelligent structural monitoring throughout. According to Xinhua, the project obtained 21 authorized patents and several of its technological innovations have since been incorporated into national bridge construction standards.

The Artificial Waterfall: Where Engineering Meets Spectacle

One of the most visually arresting features of the Huajiang canyon bridge is the artificial waterfall curtain. Before opening, the bridge underwent a water curtain test that saw water cascading in a curtain-like flow from the structure, generating a rainbow that stretched across the canyon below. According to CGTN, the display created what observers described as a dreamlike scene, with the canyon walls amplifying the spray into a shifting veil of mist and color.

This “liquid wall” effect became one of the most shared images of the bridge’s pre-opening period and is now integrated as a tourist attraction in its own right. Paired with the canyon’s natural scenery, which already includes a natural waterfall visible from the bridge deck, the engineered water curtain reinforces the project’s ambition to be far more than an infrastructure crossing.

Economic and Social Impact on Guizhou Province

Guizhou has historically been one of China’s poorest and least accessible provinces. With no flat plains anywhere in the region, movement between communities depended on winding mountain roads and long bus journeys. Wu Chaoming, the construction project manager who grew up in a rural Guizhou village, recalled taking a single daily bus to the county seat, then another to the provincial capital of Guiyang, with people crowding onto roof luggage racks. Today, that same cross-provincial journey is hours faster, and the Huajiang canyon bridge is one reason why.

By cutting the canyon crossing from two hours to two minutes, the bridge dramatically improves access to markets, healthcare, and employment for communities on both sides of the gorge. Local officials report that the village of Huajiang, which sits beneath the bridge, was fully booked at every guesthouse around the opening date, with visitors arriving specifically to witness the new structure. The bridge forms part of the Liuzhi-Anlong Expressway, a major north-south economic corridor in central and western Guizhou, and is expected to reduce pressure on the parallel Shanghai-Kunming expressway.

The broader context is China’s ongoing infrastructure investment in its southwestern provinces, framed around poverty alleviation and rural revitalization. Since 2012, Guizhou has accelerated bridge construction at a pace that has increased its total bridge count tenfold compared to the 1980s. The Huajiang Canyon Bridge is the most visible result of that push to date.

How Does It Compare to Other Famous Bridges?

Placing the world’s highest bridge in context helps understand the scale of the achievement. The Millau Viaduct in France, long considered among the most dramatic bridge structures in the world, stands 270 meters at its tallest pier. The Huajiang Grand Canyon Bridge rises more than twice that height above its valley floor. San Francisco’s Golden Gate Bridge clears the water by just 67 meters, meaning the Huajiang deck sits nearly nine Golden Gate heights above the Beipan River.

In the United States, the Royal Gorge Bridge in Colorado is the highest at 291 meters. The Huajiang bridge is more than twice as tall. At 625 meters, the bridge deck sits at approximately the same altitude above the river as the Shanghai Tower, mainland China’s tallest skyscraper at 632 meters, making it a useful visual reference: the bridge clearance alone is essentially the height of a super-tall skyscraper.

What Does the Huajiang Bridge Mean for Architecture and Infrastructure Design?

The world highest bridge in the world signals a broader shift in how large infrastructure projects are conceived. The Huajiang Grand Canyon Bridge was designed with tourism integration as a first-order objective, not an appendage. Glass floors, observation decks, a waterfall curtain, sky cafés, and bungee jump platforms were planned alongside the engineering drawings, not added after the traffic studies were done.

This “infrastructure as destination” logic reflects something important for architects and urban planners working on bridges, transit hubs, and civic structures in difficult terrain. When a project generates its own revenue streams through tourism, the economics of building in remote or underserved areas become more viable. The Huajiang model has already drawn attention from other provinces in China’s southwest and may influence bridge tourism development in mountainous regions globally.

From a structural standpoint, the project’s use of satellite navigation for high-altitude precision work, drone-assisted cable positioning, and BIM-driven coordination across a 625-meter vertical construction environment represents the practical frontier of contemporary bridge engineering. Several of the techniques developed for the Huajiang project have already been written into Chinese national bridge construction standards, according to Zhang Yin, head of the Guizhou provincial transportation department (Xinhua, 2025).

For anyone working at the intersection of architecture, engineering, and infrastructure, the ArchDaily coverage of mega-infrastructure projects and the HighestBridges.com documentation on the Huajiang canyon bridge both offer useful technical and visual depth. The original Xinhua report on the opening remains the most detailed primary source on the engineering and social dimensions of the project.

What Visitors Can Experience at the Huajiang Canyon Bridge

The Huajiang Grand Canyon Bridge functions as a complete destination rather than a crossing point. On the bridge structure itself, a 207-meter sightseeing elevator takes visitors to the sky café at the top of the south tower, approximately 800 meters above the river. The ride takes about one minute. A 1,000-square-meter glass observation hall on the bridge deck allows visitors to look directly through the floor to the canyon below. A glass walkway running beneath the truss leads to a series of elevated platforms, the highest of which reaches about 615 meters above the Beipan River.

The artificial waterfall curtain, activated by a pump system integrated into the bridge structure, creates the rainbow display that became the bridge’s most-photographed moment during pre-opening tests. Bungee jumping from the bridge will be among the world’s highest at that altitude when the facility completes its permit process. Paragliding platforms are also planned around the canyon base.

The nearby village of Huajiang, which sits on the canyon floor beneath the bridge, offers guesthouses and serves as a base for exploring older infrastructure in the area, including a chain bridge from 1898 that provides a striking contrast in bridge technology across more than a century. The wider Guizhou tourism circuit connects the Huajiang bridge to the Huangguoshu Waterfall about 50 kilometers away, which is Asia’s largest waterfall and a well-established destination.
