This structure spanning a 300-meter deep canyon is a testament to China’s superior engineering capabilities.
China is one of the countries with a top-tier modern bridge and road system. The “engineering wizards” of China have amazed the world by successfully constructing a cable-stayed bridge using just four sets of cables, without any supports or suspenders, spanning the Dadong River canyon, which is up to 300 meters deep.
Cable-stayed bridge using just four sets of cables, without supports or suspenders, spanning the Dadong River canyon.
This bridge is located in the Wulong District, Chongqing, China. It is 4.3 meters wide, 245 meters long, and has a load capacity of 45 tons. A truck carrying construction materials weighing 45 tons can safely cross this “paper-thin” bridge.
According to Xinhua, the bridge over the Dadong River canyon was originally constructed by a team of builders as a temporary bridge to transport materials for another bridge currently under construction. This temporary structure supports the building of the Shuangbao Bridge, a larger and more impressive project.
Once completed, the Shuangbao Bridge, spanning the Dadong River and Xiaohegou, will be the largest double-arch bridge in the world. Therefore, to facilitate construction, workers had to install a temporary bridge to access the nearby small mountain.
This “temporary” bridge has significantly shortened the travel distance, eliminating the need for a lengthy 30 km detour. This not only reduces costs but also minimizes unnecessary environmental impact.
From complex projects that challenge engineering norms to temporary bridges, China has earned global recognition for its infrastructure building capabilities.
