BEIJING, China, Aug 26 \u2014 A fleet of 96 trucks weighing a whopping total of 3,360 metric tons drove down the world\u2019s highest bridge under construction \u2014 the Huajiang Grand Canyon Bridge in Guizhou province \u2014 on Monday to test its load-bearing capacity.<\/strong><\/p>\n

The simulated traffic congestion was the final structural performance test for key bridge components under heavy load, marking a crucial step toward the bridge\u2019s opening in September.<\/p>\n

After five days of intensive and orderly inspections, the load test \u2014 a comprehensive \u201cphysical examination\u201d essential for verifying the bridge\u2019s structural safety and load-bearing capacity \u2014 was completed successfully.<\/p>\n

\u201cPreliminary analysis of the load test data shows that all measured indicators responded normally,\u201d said Han Hongju, deputy general manager and chief engineer of Guizhou Communications Investment Group, the company that built the bridge.<\/p>\n

Stretching 2,890 meters in total length with a main span of 1,420 meters, the bridge towers 625 meters above the Beipan River.<\/p>\n

Longest bridge span<\/h2>\n

Once open, it will be the world\u2019s highest bridge and longest bridge span in mountainous terrain.<\/p>\n

To describe the world-class project, the builders used a vivid analogy of two \u201csky-high trees\u201d 1,420 meters apart, connected by a giant \u201cclothesline\u201d that is 2,378 meters long and nearly 1 meter thick.<\/p>\n

From this \u201cclothesline\u201d, 91 pairs of \u201changers\u201d are suspended vertically, spaced 15.4 meters apart. Below these hangs a large \u201cclothes-drying platform\u201d \u2014 the bridge deck \u2014 which is 8 meters high, 30.5 meters wide, and weighs approximately 22,000 tons.<\/p>\n

The \u201csky-high tree\u201d on the Liu\u00adzhi side in Anshun city stands 262 meters tall, while the one on the Anlong side in the Qianxinan Bouyei and Miao autonomous prefecture touches 204 meters. At the top of each \u201ctree\u201d, a \u201csaddle\u201d is installed to ensure the \u201cclothesline\u201d performs smoothly and is firmly anchored.<\/p>\n

In technical terms, the \u201cclothesline\u201d refers to the main cable, the \u201changers\u201d are the suspenders, the \u201csky-high trees\u201d are the main towers, the \u201csaddles\u201d are the cable saddles, and the \u201cclothes-drying platform\u201d is the main girder.<\/p>\n

Dynamic and static assessments<\/h2>\n

The test was designed based on the bridge\u2019s intended vehicle load capacity. Through both dynamic and static assessments, the performance of the four major systems was thoroughly evaluated.<\/p>\n

Originally scheduled to be conducted from Thursday to Saturday, the static load test was rescheduled due to unpredictable weather conditions. The tests were finally carried out from Thursday to Monday, with a break in work on Saturday.<\/p>\n

Lei Min, technical director of the Bridge and Tunnel Division of Gui\u00adzhou Shunkang Testing, said that three weight classes \u2014 18, 48 and 96 trucks, with each weighing 35 tons \u2014 were used sequentially, with the maximum load reaching 3,360 tons, to test the bridge\u2019s load-bearing capacity.<\/p>\n

\u201cThis approach simulated varying traffic volumes and load distributions while ensuring there was no damage to the bridge structure,\u201d he said.<\/p>\n

Construction of the bridge began in January 2022, and the bridge is expected to open to traffic in late September.<\/p>\n

A key project component of the Liuzhi-Anlong Expressway, the bridge will reduce travel time between the two sides of the canyon from two hours to just two minutes.<\/p>\n

It is also expected to enhance regional tourism by linking attractions such as the Huangguoshu Waterfall, Longgong Cave and Wanfenglin scenic area, helping create a world-class tourism destination.<\/p>\n

\u201cThe bridge itself is a world-class attraction,\u201d said Zhang Xiangyu, a member of the bridge and tourism integration team at Guizhou Communications Investment Group.<\/p>\n

The builders have integrated modern facilities as well as experience-based activities such as bungee jumping, paragliding and rope swinging from the bridge structure, Zhang said.<\/p>\n
