Guizhou’s Huajiang Canyon Bridge Officially Enters the Guinness World Records with a Deck Height of 626.01 Meters, Claiming the Title of “World’s Highest Bridge”! Surpassing the previous record set by Beipanjiang First Bridge at 565.4 meters by 60.61 meters, it sets a new benchmark in human bridge engineering. As a key control project on Guizhou’s Liu’an Expressway, this steel truss suspension bridge not only boasts the world’s highest deck but also features a main span that stands as a global standard. Hailed as a “super project with world-firsts in every dimension,” it has, since opening on September 28, 2025, served as an “aerial artery” connecting the remote mountainous regions of western China.
Guinness World Records Official Representative Luo Qiong Announced On-Site: “The Huajiang Canyon Bridge has been officially confirmed with a height of 626.01 meters.” A representative from Guizhou Communications Investment Group stated that this certification serves as an international endorsement of China’s infrastructure prowess. Chinese engineers not only built this world-class mega-project under the complex geological conditions of western China but also leveraged domestically developed technologies to precisely define a new standard of engineering excellence unique to China.
The safe operation and maintenance of a mega-project relies on robust support from professional audio and video systems. As a specialized audio-visual manufacturer with deep industry expertise, VOKON leveraged its outstanding product capabilities, strict quality standards, and extensive engineering experience to become the audio-video solution provider for Guizhou’s Huajiang Canyon Bridge. VOKON delivered a customized broadcasting and AV system for this world-class bridge, offering all-scenario adaptability and round-the-clock stability, creating a “sound barrier” that ensures the bridge’s safe operation.
Facing the extreme conditions of the Huajiang Canyon area—large temperature fluctuations, strong winds and heavy rain, complex terrain, and easily disrupted signals—VOKON custom-designed outdoor waterproof broadcast columns, becoming the bridge’s “hardcore” audio safeguard. These columns feature high protection ratings, being dustproof, waterproof, and resistant to strong interference, ensuring stable operation in harsh weather including high temperatures, heavy rain, and strong winds. With powerful sound penetration, they deliver clear audio coverage across the entire bridge without dead zones. Paired with VOKON professional microphones, which offer high sensitivity, low noise, and strong anti-interference capabilities, operational commands and visitor guidance can be captured precisely while effectively filtering traffic and canyon wind noise for high-fidelity sound transmission. In emergency situations, the system responds rapidly, ensuring commands are accurately delivered, providing round-the-clock audio support for the safe operation of the bridge.
VOKON, grounded in the practical needs of mega-projects, moves beyond generic products, providing professional audio-visual technology tailored for high-bridge scenarios. From protection and sound transmission to precise multi-scenario optimization, VOKON leverages the hard power of domestically developed technology to safeguard the world’s highest bridge.
From the heights of Mount Everest to canyon-spanning bridges, VOKON has been deeply engaged in China’s major engineering projects, continuously empowering critical infrastructure with professional products and customized solutions.
