Q & A

What makes the Huajiang Canyon Bridge the world's highest bridge?

The Huajiang Canyon Bridge is the world’s highest due to its towering height of 625 meters above the Bay-Pan River. This surpasses many other bridges in terms of elevation, making it the tallest bridge on the planet.

How long is the Huajiang Canyon Bridge?

The Huajiang Canyon Bridge stretches a remarkable 2,890 meters in total length, with a main span of 1,420 meters.

What unique features can visitors experience at the Huajiang Canyon Bridge?

Visitors can experience a glass walkways, a sightseeing elevator, and even a sky cafe located at the top of the bridge, offering coffee 800 meters above the canyon.

How does the construction team manage the risks posed by canyon winds and heavy rain?

The construction team faces extreme weather conditions, with wind speeds often exceeding level 6 and gusts reaching level 14. To mitigate these challenges, hoisting operations are suspended during storms, and precise technology is used for safe and efficient operations.

How does the Huajiang Canyon Bridge ensure precision during construction?

The bridge’s construction used advanced techniques, such as the Beidou satellite navigation system, which helped achieve millimeter-level precision. The bridge's 93 steel truss segments were lifted and placed with an intelligent hoisting system to ensure accurate alignment.

What are the main challenges involved in transporting steel truss segments for the bridge?

The main challenge was transporting steel truss segments that were too wide to pass through the transport channel. To solve this, each segment was rotated 90 degrees, allowing it to fit through and ensuring sufficient clearance during transport.

What innovative technologies were employed in the construction of the Huajiang Canyon Bridge?

Innovative technologies like an automated eight-column transport trolley, synchronized jacks for lifting, and an intelligent cable hoisting system were used to increase efficiency and reduce safety risks during construction.

What’s the significance of the skydiving experience at the Huajiang Canyon Bridge?

The skydiving experience at the Huajiang Canyon Bridge is notable because it offers one of the most extreme thrills available, with the jump from over 600 meters above the canyon, higher than a 200-story building.

How is the bridge illuminated at night?

At night, the bridge transforms into a colorful spectacle, with powerful lasers dancing across its suspension cables, projecting brilliant hues that illuminate the surrounding landscape and ripple across the water.

What makes the Huajiang Canyon Bridge both a transportation and tourism destination?

The bridge serves not only as vital infrastructure but also as a tourism destination. It features sightseeing corridors, observation platforms, and leisure areas, offering visitors panoramic views of the canyon and a chance to admire the bridge’s architecture.
