Guangdong speeds up the construction of transportation infrastructure and stands up the "backbone" of the development of Dawan District
2022-02-25
In early spring and February, the 2022 Spring Festival transportation is coming to an end, but the traffic on the Nansha bridge is still flowing. As the first people's livelihood project and the core channel of Dawan District put into use after the release of the outline of the development plan of Guangdong, Hong Kong and Macao, Nansha bridge has undertaken about half of the river crossing traffic on the East and west sides of the Pearl River since its completion in 2019. In 2021, the traffic flow of the bridge will exceed one million in seven days of the National Day holiday alone. In the future, Nansha bridge will also form a group of sea and river crossing channels in Dawan district together with the Shenzhen China channel under construction, Huangmao Haitong Road, the completed Hong Kong Zhuhai Macao Bridge and Humen Bridge, so as to speed up the economic development of Dawan district. The "lion ocean channel" is first mentioned in the national plan In January 2022, the State Council issued the development plan of modern comprehensive transportation system in the 14th five year plan (hereinafter referred to as the plan), which clearly proposed to promote the interconnection of infrastructure in Guangdong, Hong Kong and Macao Bay area and build international comprehensive transportation hub clusters such as Guangdong, Hong Kong and Macao Bay area. The plan proposes that the construction of Shiziyang and Lianhuashan channels at the Pearl River Estuary should be started in due time in the key projects of river and sea crossing. This is also the first time to mention the construction of river crossing channels in Dawan district such as Shiziyang channel and Lianhuashan channel at the national level. As another Pearl River estuary river crossing channel that Guangdong has promoted planning and construction since the release of the outline of the development plan for Guangdong Hong Kong Macao Bay area, how to build the Shiziyang channel between Nansha bridge and Humen Bridge? When will it start? What will the future look like? More than a month ago, the mobilization activity for the construction of the first project of Shiziyang channel held in Guangzhou released the "fixed makeup photos" and "specific coffee positions" of Shiziyang channel. It is reported that as a river crossing channel connecting the three metropolitan areas of Guangdong, Hong Kong and Macao, the Shiziyang channel in the design and planning is not only a "double-layer Expressway in Dawan district", but also a "one-step river crossing" with a double-layer steel truss suspension bridge with a main span of 2180m, and there will be no more piers in the river center, It will also create five world firsts in "main span, number of lanes, height of main tower, anchorage foundation and main cable scale". "Hushengwei" of "hard core" project in Dawan District In the first week after the Spring Festival of the year of the tiger, on the West Bank of the Pearl River, on the coast of the South China Sea and on the vast Huangmao sea, the cross sea passage of the Huangmao sea is like a giant dragon winding and lying between the sea and the sky, and the machines roar on the scene. After seizing the "golden period" of the Spring Festival construction, more than 5000 builders started the project construction of the year of the tiger Bay area with "speed and passion". As the first cross sea channel project to start construction after the release of the outline of the development plan for the Great Bay area of Guangdong, Hong Kong and Macao, the Huangmao sea cross sea channel has a total length of about 31 kilometers. As the West extension of the Hong Kong Zhuhai Macao Bridge, it is expected to form the Hong Kong Zhuhai Jiangmen western Guangdong channel after its completion in 2024, changing the current situation of the single channel between the coastal area of western Guangdong and the core area of the bay area. On February 15, during the Lantern Festival, a pilot cable with a total length of 2000 meters successfully crossed the 1666 meter wide water area of Lingdingyang, and the East-West main tower of Lingdingyang bridge of deep and medium channel successfully realized the "one kilometer one-line traction". In the spring of 2022, Lingdingyang bridge will gradually carry out the erection of air construction channel catwalk. At present, the deep and medium channel immersed tunnel of Dawan super sea crossing cluster project integrating "bridge, island, tunnel and underwater interconnection" has completed the sinking and docking of 22 pipe joints; The construction of the East and West artificial islands has been carried out in an orderly manner. The box girder erection and stay cable erection of Zhongshan Bridge are under way, and it is expected to be completed and opened to traffic in 2024. Building a comprehensive three-dimensional transportation network The one belt, one road, is one of the five strategic positions of Guangdong, Hong Kong and Macau, the party's secretary and chairman Deng Xiaohua said. Speeding up the construction of transportation infrastructure will further strengthen the backbone of the development of the bay area. He introduced that at present, the mileage of Expressway in Dawan District exceeds 4500 kilometers, and the rapid transportation network has been basically formed, which has effectively promoted the interconnection of people flow, logistics, capital flow and information flow. However, the traffic volume of Guangzhou Shenzhen, Zhongjiang, Guangdong Jiangxi, Humen Bridge, Nansha bridge and other sections has tended to be saturated or supersaturated. Next, Guangdong Communications Group will speed up the construction of river crossing channels such as Shenzhen China channel and Shiziyang channel; Reconstruction and expansion of road sections with large traffic flow to improve traffic capacity. At the same time, with the help of smart highway and digital highway, build a highway operation service system supporting one hour life circle in Dawan district. The "to do list for 2022" issued by Guangdong transportation department also makes it clear that in 2022, we will accelerate the promotion of cross sea channels such as Shenzhen China channel and Huangmao Haitong Road, strive to build eight expressway projects such as Zhongshan Western outer ring road, and build a comprehensive three-dimensional transportation network with efficient connection between inside and outside.
