After seven years of sharpening a sword, 10,000 builders dreamed of the miracle of the world. On June 30, another high-profile super project was completed and opened to traffic!
On the vast and vast sea, during the day, in the golden sunshine, the deep channel from the water to the underwater penetrates the clouds and waves, like a hidden dragon going to sea, on this majestic "traffic backbone", the development of the Guangdong-Hong Kong-Macao Greater Bay Area has entered the fast lane, which is the high-spirited and progressive development of Guangdong; At night, in the bright moonlight, the 24-kilometer-long Shenzhong Passage Changhong Lying Wave, like a tenacious flat shoulder, in the "High-quality Development Project of 100 Counties, Thousands of Towns and Thousands of Villages", let the Pearl River Delta provoke eastern Guangdong at one end and western Guangdong at the other, and the infrastructure aims to solve the pain points restricting urban and rural development, which is the equality and gentleness of Guangdong's regional coordinated development.
A bridge flying in the depths, "zero dingyang" is no longer "zero ding". From a satellite perspective, the Guangdong-Hong Kong-Macao Greater Bay Area is accelerating its integration, and both sides of the Pearl River are poised to take off!
Seven years of sharpening a sword to build a dream of "the best in the world"
"Zero Ding Yang sighs Zero Ding". More than 700 years ago, Wen Tianxiang, a patriotic poet of the Southern Song Dynasty, once looked at the ocean here and sighed. Today, more than 10,000 builders from the north and south of the river have "sharpened a sword in seven years", erected heavenly roads, built the Great Wall, and built twin islands on the Lingding Ocean, one after another infrastructure "miracles", making "sighing Lingding" become "cross-giant changes".
The Shenzhen-Zhongshan Corridor is the most critical "horizontal" of the "A" shaped traffic skeleton of the Pearl River Estuary, integrating "bridges, islands, tunnels and underwater hubs", and is one of the most difficult cross-sea cluster projects in the world.

In the world's first two-way eight-lane submarine immersed tube tunnel, the world's largest span offshore suspension bridge and other fields, the Shenzhen-Zhongshan Channel has created more than 10 world records. The Shenzhen-Zhongshan Corridor has given full play to the strategic leading position and fundamental supporting role of science and technology, and has formed 10 world-leading technologies such as "Design Method for Steel Shell-Concrete Immersed Tunnel Tunnel". Since its construction, the Shenzhen-Zhongshan Corridor has won more than 200 invention patents, dozens of industry association awards, and has won many international acclaims: in April 2024, the Shenzhen-Zhongshan Bridge won the "George Richardson Award" at the International Bridge Conference, and the Shenzhen-Zhongshan Tunnel was awarded the "50 Landmark Projects in the Field of Global Tunneling and Underground Engineering".
"Guangdong will improve the accessibility and service efficiency of the road network with new quality productivity, further improve the highway network along the Shenzhen-Zhongshan Corridor and the surrounding areas, and provide efficient and safe 'hard connectivity' support for the development of the Greater Bay Area." Lin Feiming, director of the Guangdong Provincial Department of Transportation, said that the Shenzhen-Zhongshan Corridor has the most cutting-edge technology of infrastructure construction in the mainland, which is a vivid portrayal of accelerating the construction of a transportation power, and its completion and opening to traffic will completely change the overall road grid bureau of the Pearl River Estuary, which is of great significance to the economic and social development of the Guangdong-Hong Kong-Macao Greater Bay Area.
As one of the key control projects of the Shenzhen-Zhongshan Channel, in order to meet the needs of navigation, the Shenzhen-Zhongshan Bridge adopts the world's largest full-span offshore suspension bridge scheme with a main span of 1,666 meters, with a bridge deck of up to 91 meters.
"In the face of technical challenges, we have organized a number of universities and scientific research institutions to carry out more than 3 years of parallel research in a four-in-one way of production, learning, research and use, and developed a new combined pneumatic control technology, which has greatly improved the wind resistance of large-span integral steel box girder suspension bridges for the first time in the world." Song Shenyou, director and chief engineer of the Shenzhong Channel Management Center of Guangdong Communications Group, said that the project will increase the critical flutter wind speed of the large-span steel box girder suspension bridge from 70 m/s to 88 m/s, breaking the authoritative assertion of foreign countries in one fell swoop.
Cable is one of the key components of the suspension bridge, how to ensure durability in the face of high temperature, high humidity and high salt in the harsh environment? In order to make the "lifeline" of the suspension bridge stronger and more durable, the builders of the Shenzhen-Zhongshan Corridor project focused on the core key technologies that restrict the durability of the main cable of the suspension bridge, and the team developed a 6mm-2060 megapascal zinc-aluminum multi-alloy coated steel wire strand for the first time in the world, and its corrosion resistance is twice that of the previous hot-dip galvanized aluminum alloy steel wire.
The Shenzhong Corridor Undersea Tunnel is about 6.8 kilometers long, and the total steel consumption is three times that of the "Bird's Nest" of the National Stadium. The steel-shelled concrete immersed tunnel is about 5 kilometers long and is divided into 32 pipe sections and 1 final joint. The standard section is 165 meters long and stands up to a 55-story building.
The docking of the final joint is like a "seabed needle", and the error should be controlled at the "millimeter level". In order to achieve this difficult goal, after two years of technical demonstration and one year of joint design, the builders pioneered a new process of integral prefabricated underwater push-out final joint of immersed tube in the world.
"Through the control system based on Beidou measurement, we have achieved a 'millimeter-level' plane installation accuracy of 15 pipe sections." Song Shenyou said that the steel-shell concrete immersed tunnel has made a number of original innovations in terms of design theory, manufacturing process, new materials, large-scale equipment and final joints, which has effectively promoted the technological progress of the mainland immersed tunnel and enriched the "Chinese plan" and "Chinese standard" of the world's cross-sea immersed tunnel.
The "Golden Inner Bay" enhances the gold content and accelerates the integration of the Greater Bay Area
The report of the 13th Party Congress of Guangdong Province pointed out that it is necessary to improve the level of integration, take the integrated development of the east and west banks of the Pearl River Estuary as a breakthrough, deepen the docking and integration of infrastructure, industrial development, and social governance, promote the pilot project of integrated high-quality development of the Pearl River Estuary in the Guangdong-Hong Kong-Macao Greater Bay Area, and strive to build a 100-kilometer "golden inner bay" around the Pearl River Estuary, so as to drive the coordinated development and take-off of the three major metropolitan areas of Guangzhou, Shenzhen and the west bank of the Pearl River Estuary.

As the main transportation artery connecting the urban agglomerations on the east and west banks of the estuary, the importance of the Shenzhen-Zhongshan Corridor is self-evident. Deng Xiaohua, chairman of Guangdong Communications Group, said that as the new "traffic backbone" of the Guangdong-Hong Kong-Macao Greater Bay Area and the key "horizontal" of the "A" shaped transportation network framework, the Shenzhen-Zhongshan Corridor has shouldered the important mission of promoting better connection and integration between the east and west banks of the Pearl River Estuary since the design stage. With the imminent opening of this corridor, the "gold content" of the "Golden Inner Bay" of the Pearl River Estuary will be greatly enhanced, which will have a profound impact on the regional development pattern of the Guangdong-Hong Kong-Macao Greater Bay Area.
After the completion and opening of the Shenzhen-Zhongshan Corridor, the driving time between Shenzhen and Zhongshan will be shortened from 2 hours to 30 minutes, and the two places will join hands to enter the "half-hour living traffic circle".
"I remember when I was a child, my parents took me to Zhongshan Hot Spring, an hour from Hong Kong to Macau, then transfer to Zhuhai Special Economic Zone, and then transfer to Zhongshan, it took nearly a day to walk from Hong Kong to Zhongshan, and now I take my children to Zhongshan in less than an hour." Fok Qigang, a deputy to the National People's Congress and a member of the Hong Kong Legislative Council, said, "The Guangdong-Hong Kong-Macao Greater Bay Area has changed the living habits of a generation. ”
Shenzhen and Zhongshan face each other across the Pearl River estuary, and more and more enterprises are staging the story of "A Tale of Two Cities" in Shenzhen and Zhongshan, and the industrial chain and innovation chain of the two places are deeply integrated.
Founded in 2006, Shenzhen Xinyichang Technology Co., Ltd. is an enterprise mainly engaged in the research and development, production and sales of intelligent manufacturing equipment in LED, semiconductor, capacitor and other industries. Due to business expansion, the company has to travel back and forth to Shenzhen and Zhongshan many times a week from leaders to employees.
"The upcoming opening of the Shenzhen-Zhongshan Corridor is a golden avenue for us, in the past, from the R&D center in Nanshan District, Shenzhen to the factory in Zhongshan, it took more than two hours, after the opening of the Shenzhen-Zhongshan Channel, the driving time will be shortened to less than 30 minutes." Yuan Jasmine, director of the company's president's office, said that since 2017, the company has entered a stage of rapid development, with annual sales climbing from five or six billion yuan per year to more than one billion. In the future, it will form a layout of "three points and one line" with headquarters in Bao'an Central District, Shenzhen, R&D center in Nanshan Science and Technology Park, Shenzhen, and production base in Cuiheng New District, Zhongshan.
Meng Fanli, Secretary of the Shenzhen Municipal Party Committee, said that to play a key role in major projects such as the Shenzhen-Zhongshan Corridor, Shenzhen will launch more new measures to facilitate the travel of citizens between the two places, further smooth the flow of people, logistics, information and capital flows, and other factors, and promote industrial innovation and cooperation in a coordinated manner. We will work together to build a world-class advanced manufacturing cluster, vigorously develop the modern service industry, and accelerate the construction of a future-oriented modern industrial system; Strengthen exchanges and cooperation in various fields such as business environment, cultural tourism, people's livelihood, and social governance, and create a "cross-city non-sense" production and living environment...... Shenzhen is promoting the integration and interaction between the east and west sides of the Pearl River Estuary, and striving to make new and greater contributions to the construction of the Guangdong-Hong Kong-Macao Greater Bay Area and the overall development of the province.
In the Zhongshan Shenzhen-Zhongshan Economic Cooperation Zone, a modern factory building has risen from the ground, the construction of the second phase of BYD's Zhongshan factory has been accelerated, and the Chengyi flat panel display device project has been successfully capped. With the advantages of location and space, as well as a good industrial foundation, it has attracted 71 high-quality enterprises. Shenzhen will join hands with the mountains to jointly cultivate new quality productivity, and will jointly cultivate a number of 100-billion-level industrial clusters such as electronic information, health medicine, and new energy.
A 20-minute drive shortens not only the geographical distance between Shenzhen and Zhongshan. "The Shenzhen-Zhongshan Corridor has realized the integrated and interactive development of the east and west banks of the Pearl River Estuary, allowing Shenzhen and Zhongshan, which are facing each other across the river, to shake hands and closely connect each other, opening a new milestone in the integration and development of Shenzhen-China and the same city." Guo Wenhai, secretary of the Zhongshan Municipal Party Committee, said that Zhongshan will resolutely implement the experimental zone for integrated development, reform and innovation on the east and west banks of the Pearl River Estuary deployed by the provincial party committee, and more actively promote the "six integrations" of planning, business environment, industry, transportation, innovation, public service and social governance in Shenzhen.
Zhongshan will seize the historic opportunity of the Shenzhen-Zhongshan Corridor, transform its location advantages into high-quality development victories, and make Zhongshan's positive contribution to the construction of a world-class bay area." Guo Wenhai said.
At present, the Guangdong-Hong Kong-Macao Greater Bay Area Expressway has been opened to traffic for more than 4,500 kilometers, and a rapid transportation network has been basically formed. After the completion and opening of the Shenzhen-Zhongshan Corridor, it will work with the Humen Bridge, Nansha Bridge, Guangzhou-Shenzhen Expressway, Guangzhou-Zhuhai East Line, Guangzhou-Zhuhai West Line and other channels to form a chain of urban agglomerations in the Guangdong-Hong Kong-Macao Greater Bay Area, build a new pattern of one-hour economic circle in the Greater Bay Area, and further promote the interconnection of people, logistics, capital and information flows on both sides of the Pearl River.
Overlooking the Guangdong-Hong Kong-Macao Greater Bay Area, Nansha District of Guangzhou is located in its geometric center. Through the Wanqingsha branch line of the South-Central Expressway, Nansha will be directly connected to the Shenzhen-Zhongshan Corridor and "hold hands" with Shenzhen and Zhongshan on the Lingding Ocean. It is expected that after the completion and opening of traffic within this year, the driving time from Nansha to Shenzhen will be shortened to less than 20 minutes, and the driving time to Zhongshan city will be shortened to less than 15 minutes.
"The completion and opening of the Shenzhen-Zhongshan Corridor has further facilitated the transportation links between Nansha and the east and west banks of the Pearl River Estuary, helped Nansha build a comprehensive transportation three-dimensional system that 'integrates the world, connects Hong Kong and Macao, and directly connects the Bay Area', and creates a strategic fulcrum for the integrated development of the east and west banks of the Pearl River Estuary." Liu Wei, member of the Standing Committee of the Guangzhou Municipal Party Committee and secretary of the Nansha District Party Committee, said that the opening of the Shenzhen-Zhongshan Corridor will also bring opportunities for Nansha to better integrate into the "Golden Inner Bay", promote Nansha to speed up the planning and industrial introduction of the biological valley, digital valley, health valley and the southern area of Wanqingsha, undertake innovative resources on the east and west sides of the strait, and strive to build a demonstration area for the integrated development of industries in Guangzhou and Shenzhen, and drive the construction of a 100-kilometer "golden inner bay" around the Pearl River Estuary.
"Opening up to the world is an important mission and unique temperament of Nansha, and the opening of the Shenzhen-Zhongshan Corridor will further enhance the level of Nansha's internal and external opening-up, help Nansha accelerate the construction of the energy core and new growth pole of the Greater Bay Area, and build a major strategic platform based in the Bay Area, cooperating with Hong Kong and Macao, and facing the world." Liu Wei said.
Shenzhen and Zhuhai are located at the east and west ends of the Pearl River estuary, after the opening of the Shenzhen-Zhongshan Channel, the driving time between the east of Zhuhai and the west of Shenzhen will be shortened from 2 hours to 1 hour, Shenzhen and Zhuhai will enter the "one-hour life circle", Shenzhen and Zhuhai between the city industrial coordination, resource sharing, innovation and entrepreneurship support has been greatly improved, Shenzhen and Zhuhai two special economic zones will usher in an epic handshake, and the flow of factors between the two places will be smoother.
Chen Yong, secretary of the Zhuhai Municipal Party Committee, led a team to Shenzhen in May to inspect and study, he said that Zhuhai will strengthen all-round cooperation with Shenzhen, work together to do a good job in the construction of major cooperation platforms such as Hengqin, Qianhai and Hetao, accelerate the coordinated development of Hong Kong, Shenzhen and Macao-Zhuhai, and actively plan the construction of the Shenzhen-Zhuhai channel and the in-depth docking of airports and seaports, strengthen industrial and technological cooperation, and jointly promote the two-way transfer and transformation of innovative achievements, so as to better serve the overall situation of the whole province.
"Zhuhai will consciously assume the core responsibility of the strategic starting point of western Zhuhai, take on the responsibility of 'head goose' in driving the development of western Zhuhai and western Guangdong, activate the 'wild goose effect', and play a core and leading role in accelerating the development of the west bank of the Pearl River." Chen Yong said.
"Short board" becomes "potential board" The Pearl River Delta has driven eastern and western Guangdong to take off
At present, Guangdong's "High-quality Development Project of 100 Counties, Thousands of Towns and Thousands of Villages" is aiming at the difficulties and pain points that restrict the development of urban and rural areas, accelerating infrastructure interconnection, improving the equalization level of public services, and at the same time, further promoting the orderly transfer of industries and enhancing the radiation and driving role of the Pearl River Delta in the underdeveloped areas of the province.
The opening of the Shenzhen-Zhongshan Corridor will not only connect Shenzhen and Zhongshan, but also the strong activation of the economic lifeline of the east and west banks of the Pearl River Estuary, which will rewrite the time and space connection between Yangjiang, Maoming, Zhanjiang and other regions in western Guangdong and Shenzhen. In addition, western Guangdong is the center of the intersection of the three national strategies of the Guangdong-Hong Kong-Macao Greater Bay Area, the Beibu Gulf urban agglomeration and the Hainan Free Trade Port, and the Shenzhen-Zhongshan Corridor will also catalyze a new chapter in the integration and symbiosis of several major urban agglomerations.

"In the past, from Shenzhen to western Guangdong, you had to take the Humen Bridge or the Nansha Bridge, and the three- or four-hour drive discouraged many tourists." Huang Chuping, assistant to the general manager of Shenzhen Xinjingjie Chuangjing International Travel Agency, as a senior tourism practitioner, has already smelled the "super traffic" brought to the tourism industry after the opening of the Shenzhen-Zhongshan Corridor.
Huang Chuping introduced that since last year, he and his team have planned the tourism products after the opening of the Shenzhen-Zhongshan Channel, not only in the Shenzhen-Zhongshan Twin Cities, but also in Foshan, Jiangmen, Zhuhai and Yangjiang, excavating the delicious food hidden in the deep alleys, visiting the monuments carved by the years, and experiencing the tranquility of the beautiful countryside. "The opening of the Shenzhen-Zhongshan Corridor is imminent, and more than 10 routes for in-depth tourism in western Guangdong have been launched, and the customer acquisition is very good." Huang Chuping said.
At present, it is an unavoidable step for the Greater Bay Area to improve the overall level of coordinated development and external competitiveness of the region, and narrow the gap between the east and west sides of the Pearl River Estuary. The construction of a balanced, coordinated and future-oriented high-speed transportation network in the Shenzhen-Zhongshan Corridor of the Greater Bay Area will reconstruct the industrial synergy pattern on both sides of the Pearl River Estuary.
With more than 40 years of rapid development, Shenzhen has completed the industrial leapfrog upgrading journey of "Shenzhen Processing, Shenzhen Manufacturing, Shenzhen Creation", and has gradually grown into an innovative city dominated by high-tech industries and with global influence. However, on the other side of rapid development, Shenzhen is also facing the bottleneck of limited land space.
"Some links of equipment manufacturing enterprises are not suitable for going upstairs, and they can only find a place with sufficient land resources and space", Tang Shanbin, sales director of Shenzhen Chevening Technology Co., Ltd., said after inspecting Jiangmen, "Jiangmen has great advantages in building a 'first-floor factory'." Lin Yipan, chairman and general manager of Shenzhen Lihexing Co., Ltd., said: "Our R&D headquarters is in Shenzhen, and our production is in Jiangmen, which is very convenient, which is a shared and win-win model."
As the capital of overseas Chinese in China and an important node city in the Guangdong-Hong Kong-Macao Greater Bay Area, Jiangmen City has also ushered in the window period and golden period of "bridge economy" along with the Shenzhen-Zhongshan Passage and the Huangmaohai Passage.
Chen Anming, Secretary of the Jiangmen Municipal Party Committee, said that Jiangmen will take advantage of the situation to implement the outline of the Greater Bay Area plan, seize the major opportunity of the opening of the Shenzhen-Zhongshan Corridor and the Huangmaohai Bridge, give full play to the comparative advantages of location, industry, land, water source and energy, accelerate the construction of a modern industrial cooperation zone with Shenzhen and Hong Kong, build a new platform for the development of Hong Kong and Macao residents and overseas Chinese, accelerate the development of six 100-billion-yuan industries such as agriculture and food, advanced materials and electronic information, and contribute to the high-quality development of Guangdong.
The transportation convenience brought by the Shenzhen-Zhongshan Corridor and Jiangmen's unique cultural and tourism resource endowment have also attracted the attention of travel agencies in Shenzhen and Jiangmen. Chen Wenfei, vice president and secretary general of the Jiangmen Tourism Industry Association, said: "Xinhui's Liang Qichao Former Residence Memorial Hall, Little Bird Paradise National Wetland Park, and Gudou Hot Spring Resort are all well-known scenic spots in the province. In the early stage, we have docked with travel agencies in Shenzhen and Hong Kong, and plan to launch routes such as Shenzhen-Jiangxi and Jiangmen in-depth tours to attract more tourists from Shenzhen, Hong Kong and Macao to visit Jiangmen. ”
Qiao Jianwei, vice president of Chikan Overseas Chinese Ancient Town Tourism Resort, said that after the opening of the Shenzhen-Zhongshan Corridor, the driving time from Jiangmen to Shenzhen will be greatly reduced.
The space-time distance between the cities on the east and west banks of the Pearl River Estuary is shortening, and the flow of people, logistics, capital and information is accelerating. On the new journey, Guangdong has firm confidence, hard work, with a high-spirited attitude, to create a new and greater miracle that impresses the world, and strive to walk in the forefront of the country in the new journey and create new brilliance!
