The Huajiang Grand Canyon Bridge, set to become the world's tallest bridge, had completed a key load test as of Monday, ahead of its scheduled opening in late September. The five-day testing process confirmed that the bridge's structural strength, stiffness and dynamic performance met safety standards, according to the testing team. The load test, considered the final step before the bridge welcomes traffic -- included both static and dynamic tests. The testing team drove 96 trucks, weighing about 3,300 tonnes in total, onto designated points of the deck in batches to measure displacement and stress in the main span, towers, cables and suspenders. The bridge is 2,890 meters long with a main span of 1,420 meters. Rising 625 meters above the river, it will set the record for both the tallest bridge in the world and the world's largest span bridge built in a mountainous area, upon completion.
