Guangzhou, April 4 (Zhongxin Net) -- On the vast expanse of the ocean, bridge towers stand, bridge decks meander into the sea, and deep-middle passages like Changhong Lying Wave connect the two banks of the Pearl River, which is about to become the "traffic backbone" supporting the development of the Guangdong-Hong Kong-Macao Greater Bay Area.
At 28:9 on the 37th, the Guangdong-Hong Kong-Macao Greater Bay Area super project Lingdingyang Bridge Helong, which also means that the project bridge project has achieved the whole line of Helong.
With a total length of about 24 kilometers, the Shenzhen-Zhongshan Corridor is located in the most critical horizontal of the "A" shaped traffic skeleton in the Guangdong-Hong Kong-Macao Greater Bay Area, and is a rare super cluster project in the world that integrates submarine steel-shell immersed tunnels, super-long-span bridges in the sea, deep-water artificial islands and underwater hubs.

The bridge project is about 17 kilometers long, including Lingdingyang Bridge, Zhongshan Bridge and Non-navigable Hole Bridge, of which the main span of Zhongshan Bridge is about 580 meters, which has been completed in June 2022; On April 6, the Lingdingyang Bridge in Helong was one of the key control projects of the project, with a main span of 4,28 meters, a main tower height of 1666 meters, equivalent to a height of 270 floors, and a navigable clearance height of 90.76 meters, ranking among the top in the world.
The first main pier pile foundation of the Lingdingyang Bridge was drilled in September 2018, and the civil engineering, main cable installation and steel box girder lifting were responsible for the civil engineering, main cable installation and steel box girder hoisting of CCCC-9 Aviation Bureau and Poly Governorate, and Wushuan Heavy Industry Co., Ltd. and China Railway Baoqiao were responsible for the manufacture of steel box girder.
At present, the expressway mileage of the Guangdong-Hong Kong-Macao Greater Bay Area has exceeded 4500,<> kilometers, and the rapid transit network has basically taken shape, which has effectively promoted the interconnection of people, logistics, capital and information.
Deng Xiaohua, Secretary of the Party Committee and Chairman of Guangdong Communications Group, said: "We will further play the role of Guangdong's transportation construction as the main force in construction, accelerate the construction of transportation infrastructure in the Guangdong-Hong Kong-Macao Greater Bay Area such as the Shenzhen-China Corridor and the Shiziyang Corridor, and make due contributions to Guangdong's development as a pilot demonstration zone for building a powerful transportation country while promoting the better integration of Hong Kong and Macao into the overall development of the country."
It is understood that after the merger of the Lingdingyang Bridge, the bridge project will fully carry out the bridge deck paving and ancillary structure construction; The subsea immersed tunnel has completed the settlement and installation of 31 pipe sections, and the second outfitting of the last pipe section (including the final joint) is being carried out, and the tunnel breakthrough is planned to be achieved by the end of this year; The construction of artificial islands in the east and west and the project in the immersed pipe have been steadily advanced; Housing construction, mechanical and electrical, power supply, traffic security and other projects will also be fully launched, and a sprint will be launched towards completion and operation in 2024.
