The Xiamen section of the Xiamen-Kinmen Bridge has entered a new phase of marine intelligent assembly construction, marked by the completion of the first precast pier lifting operation in Xiamen, east China's Fujian Province.
The Xiamen-Kinmen Bridge (Xiamen section) spans 17.34 km, with a total of 85 piers, and is designed to link the Xiamen island with the Xiamen Xiang'an International Airport that is currently under construction.
The first precast pier lifted measures 18 meters in length, 13.8 meters in width, and 13.4 meters in height, weighing around 3,000 tons.
During the lifting process, the construction unit utilized an intelligent positioning system for the extra-large precast pier, upgrading traditional manual operations to a "digital brain on the sea" that automatically corrects deviations, achieving "one-time lifting, precise placement".
"Through AI, the measured data is transmitted to the computer, and then sent to the control cabinet of our positioning system via the computer's wireless terminal, and then the unmanned operation is carried out to meet the precise positioning of the jack under unmanned operation, which can achieve millimeter-level control. This also reduces the risk of personnel operating on this equipment, which is safe and efficient,"said Deng Yuxin, deputy production manager of Xiamen-Kinmen Bridge’s A2 section at CCCC Second Harbor Engineering Company.
With a total investment of 37.27 billion yuan (about 5.15 billion U.S. dollars), the Xiamen-Kinmen Bridge (Xiamen section) will become the most efficient connection between the Xiamen island and the Xiang'an Airport. Once completed, it will ease traffic congestion and greatly enhance transport efficiency in the region.
The Xiamen-Kinmen Bridge (Xiamen section) started construction in October 2023, and is expected to be completed simultaneously with the Xiang'an Airport Expressway in 2026.
Kinmen is an important hub for interaction across the Taiwan Strait. Growing trade and commercial links between Kinmen and Xiamen have made the building of the bridge a common desire of many people in the region.
Xiamen-Kinmen Bridge enters new marine construction phase
The Guangdong–Hong Kong–Macao Greater Bay Area (GBA) is emerging as a key engine for China's fast-growing low-altitude economy by leveraging its dense industrial networks, efficient logistics systems, and rapid innovation capacity.
From logistics and manufacturing to urban services, the region is building an integrated industrial chain that allows low-altitude industries to scale up at unprecedented speed, thus turning drone-based applications from isolated trials into large-scale, commercial operations.
China's 15th Five-Year Plan, covering 2026 to 2030, calls for the cultivation of new pillar industries and the accelerated development of strategic emerging industrial clusters, including the low-altitude economy.
At a drone operations center in Bao'an District, Shenzhen City in south China's Guangdong Province, a dozen logistics drones take off and land within minutes. Urgently needed production parts, documents, and small parcels are dispatched from here to cities in the province including Dongguan, Zhongshan, and Zhuhai.
Behind these high-flying aircraft lies what observers describe as an "invisible industrial chain", built on speed and efficiency.
"Look at this aircraft. About 90 percent of its components come from nearby areas. Relying on Shenzhen's strong logistics capabilities and its complete supply chain, these parts can be delivered to our factory within half an hour for assembly, processing, and production," said Li Kunhuang, person-in-charge of Shenzhen GODO Innovation Technology Co., Ltd.
Once a new product is unveiled, testing and calibration begin immediately at the drone testing field. As soon as the process is completed, the new models can be put into real-world operation, realizing almost “zero delay” from research and development to application.
Supported by a robust industrial chain, low-altitude routes in Shenzhen are effectively connecting the urban landscape. From its Bao'an District to Songshan Lake in Dongguan City, production components can be delivered within one hour. Supplies are transported between Zhuhai City's Xiangzhou Port to Dong'ao Island in just 25 minutes. And light industrial goods can travel round-trip within a single day between Guzhen Town in Zhongshan City and Xinhui District in Jiangmen City.
More low-altitude application scenarios are expected to be implemented in the near future.
In Qianhai District, Shenzhen is accelerating the construction of a pilot demonstration zone of low-altitude integrated three-dimensional transportation hub.
"We have built the country's first low-altitude integrated three-dimensional transportation hub, and are gradually developing a pilot flight zone that integrates multiple scenarios such as inspection, logistics, and cultural tourism. This will provide technical support for the next step of commercializing cross-border logistics and emergency rescue services across the Guangdong–Hong Kong–Macao Greater Bay Area," said Wu Xuemin, head of the Shenzhen Qianhai Low-Altitude Integrated Three-Dimensional Transportation Hub Pilot Demonstration Zone.
