My lead: What is the significance of the Hong Kong-Zhuhai-Macao Bridge? The Hong Kong-Zhuhai-Macao Bridge has opened a new era for the development of the three places and brought people closer. Although Hong Kong, Zhuhai and Macao are not far apart, they have long felt a little distant from each other because of the implementation of "one country, two systems". Today, the Hong Kong-Zhuhai-Macao Bridge jointly built by the three places has brought us a great surprise. It not only shortens the distance between places, but also draws closer the spiritual distance between the mainland people and the people of Hong Kong and Macao.
The Hong Kong-Zhuhai-Macao Bridge opens a new era for the development of the three places.
Following the closure of the main bridge on June 29th, the installation of the last expansion joint of the main project of the Hong Kong-Zhuhai-Macao Bridge has been completed recently. On the morning of the 27th, the Hong Kong-Zhuhai-Macao Bridge Authority will hold a ceremony to officially announce the completion of the main project of the bridge, marking the completion of the main project of the bridge.
The 27th is destined to go down in history forever. On September 27th, 20 16, a great idea conceived for more than 30 years was finally completely integrated through the efforts of builders for nearly 7 years. The Hong Kong-Zhuhai-Macao Bridge, praised by the British newspaper The Guardian as one of the "Seven Wonders of the Modern World", now lies across the Dingling Ocean with a beautiful face, like a water dragon, connecting Hong Kong, Zhuhai and Macau. After the bridge deck pavement is fully completed, it will fundamentally change the situation that the passenger and cargo transportation channels between the west bank of the Pearl River and Hong Kong and Macao are mainly by water and bypass by land, and further improve the comprehensive transportation level of the country, Guangdong, Hong Kong and Macao.
It can be said that this is a grand cross-century project. From the initial proposal of the plan to the present, it has a real face, which contains many ardent expectations of the people of the three places, and the difficulties and hardships in the construction process can be imagined. For example, the bridge, with a total length of 55 kilometers, covers many projects in different fields such as roads, bridges, tunnels and artificial islands. It is a super aggregate of multi-discipline, multi-specialty and multi-level technologies, and many key technologies and construction methods have no experience in the world. At the same time, the bridge has the longest immersed submarine tunnel in the world, and it is the longest and most difficult cross-sea bridge in the construction history of China. Behind the largest scale, it also represents this super project, which has brought unprecedented challenges from planning and design to manufacturing and construction, from quality control to project management. For example, the wind-proof, anti-corrosion and anti-seismic technology of the bridge, the manufacture and installation of the world's largest steel box girder and bridge tower, the manufacture and floating installation of the world's longest subsea tunnel, the installation of offshore piers and abutments, and the rapid island formation of two artificial islands have set many world records.
Today, the success of the bridge is attributed to far-sighted decision makers and hardworking builders, while the convenience has benefited the people of the three places. On the one hand, it shortens the traffic distance between the three places. A flying bridge will reduce the traffic between Zhuhai and Hong Kong and Macao from three or four hours by land and more than one hour by water to only 20 to 30 minutes by car, and realize the land docking between Zhuhai and Macao for the first time, greatly shortening the distance between Hong Kong, Zhuhai and Macao. At the same time, the west end of the bridge is connected with the Beijing-Hong Kong-Macao Expressway and the national expressway network, and the east side of Hong Kong is connected with the road network in Hong Kong through Lantau Highway. This connection has narrowed the traffic distance between the three places.
Second, it has narrowed the economic exchange distance between the three places. After the opening of the project, it will open up a new situation for the transportation links between Hong Kong, Macao and the mainland, and bring new opportunities for the long-term economic development, tourism, finance, trade, commerce and logistics of the three places. Nowadays, with the construction of the Hong Kong-Zhuhai-Macao Bridge, the third runway is already under construction in Hong Kong Airport, and the North Business District of the airport is also under planning. In Zhuhai, in recent years, around how to turn the Hong Kong-Zhuhai-Macao Bridge into a bridgehead connecting Hong Kong and Macao, the city is also deeply thinking about how to optimize policies, environment and supporting facilities, and promote the construction of high-tech zones and the development of high-tech industries by undertaking the spillover and transfer of high-tech industries in the two places.
Third, it has narrowed the distance between people in the three places. Although Hong Kong, Zhuhai and Macao are not far apart, they have long felt a little distant from each other because of the implementation of "one country, two systems". Today, the Hong Kong-Zhuhai-Macao Bridge jointly built by the three places has brought us a great surprise. It not only shortens the distance between places, but also draws closer the spiritual distance between the mainland people and the people of Hong Kong and Macao. It should be said that this is a new coordinate belonging to the three places, which will surely become the spiritual imprint and love knot of the people in the three places.
In this sense, the full completion of the Hong Kong-Zhuhai-Macao Bridge may be a phased end for today's builders, but it is an increasingly close beginning for the development of the three places. May the smooth completion of the Hong Kong-Zhuhai-Macao Bridge open a new era for the development of the three places, and we eagerly look forward to the realization of this vision in the near future.
Significance of Hong Kong-Zhuhai-Macao Bridge Construction
The Hong Kong-Zhuhai-Macao Bridge has become the longest sea-crossing bridge in the world. As a cross-sea bridge project with the longest mileage, the largest investment and the most difficult construction in China's construction history, the Hong Kong-Zhuhai-Macao Bridge has attracted wide attention at home and abroad. The Hong Kong-Zhuhai-Macao Bridge will connect the most dynamic economic zone in the world, and the completion of the expressway has far-reaching significance for the economic and social integration of Hong Kong, Macao and Zhuhai. The planned 29-kilometer-long bridge is expected to cost 2 billion dollars. Upon completion, it will become the fourth bridge in the world after Pontchartrain Lake Bridge, Ningbo Hangzhou Bay Bridge and Jiaozhou Bay Bridge. After it is completed and opened to traffic, the journey from Hong Kong to Zhuhai will be shortened from the current three hours to more than half an hour.
The Hong Kong-Zhuhai-Macao Bridge project spans Lingdingyang, connecting Hong Kong to the east and Zhuhai and Macau to the west. It is the first large-scale cross-sea traffic project jointly built by Guangdong, Hong Kong and Macao under the framework of "one country, two systems" and the longest cross-sea bridge project in the world. The "Century Project" Hong Kong-Zhuhai-Macao Bridge started in Zhuhai from June 5438 to February 65438. After the project is completed, it takes only half an hour to drive from Hong Kong to Zhuhai, and Guangdong, Hong Kong and Macao will be closely connected.

The main project "Haizhong Bridge Tunnel" is 35.578 kilometers long.
Hong Kong-Zhuhai-Macao Bridge belongs to G94 Pearl River Delta Ring Expressway with a design speed of 100- 120km per hour. The route of the project starts from the artificial island of Hong Kong Port near the Hong Kong International Airport, connects the artificial island of Zhuhai/Macau Port and the Zhuhai connecting line in the west, and ends at Hongwan, Zhuhai, with a total length of 55 kilometers.
It is a large-scale cross-sea passage in the form of a highway bridge across the Lingdingyang sea area of the Pearl River Estuary, connecting Hong Kong, Zhuhai and Macao. The Hong Kong-Zhuhai-Macao Bridge starts from Lantau Island, Hong Kong, passes through Tai O, crosses the Pearl River Estuary, and finally divides into a Y shape, with one end connected to Zhuhai and the other end connected to Macao. The whole bridge will be built according to the standard of six-lane expressway, with a design speed of 100 km per hour.
According to reports, the Hong Kong-Zhuhai-Macao Bridge will pass through Gongbei built-up area towards Zhuhai. It will first connect with the planned Beijing-Hong Kong-Macao Expressway Guangzhou-Zhuhai West Line, and then connect with a series of main roads in Zhuhai, such as the existing Beijing-Zhuhai Expressway, the Western Coastal Expressway, the Zhu Jiang Expressway, the planned Airport Expressway and the Gaolan Port Expressway, and will run through the entire west bank of the Pearl River and even the Pan-Pearl River Delta region.
Use measures
The proposed Hong Kong-Zhuhai-Macao Bridge is 49.968 kilometers long, of which the main project "Haizhong Bridge Tunnel" is 35.578 kilometers long. The main project of Haizhong Bridge Tunnel and Zhuhai Connection will be built according to the standard of six-lane expressway, and the designed driving speed is per hour 100 km. The whole bridge costs more than 72 billion yuan, which is jointly funded by the central government and the governments of Guangdong, Hong Kong and Macao. The planned toll is 50 years.
As for the toll that people are most concerned about, according to the forecast in the feasibility study report, the toll for private cars in the two schemes is 150 yuan. However, recently, the Secretary for Transport and Housing, eva cheng, said that according to the latest financing arrangements, the governments of the three places have the hope to reduce the bridge toll as much as possible. For example, private cars are estimated to charge RMB 65,438+000 per trip, and trucks in 200 yuan are even lower. Relevant departments stressed that the Hong Kong-Zhuhai-Macao Bridge will be completed and opened to traffic for several years, and the final charging standard will be determined and announced according to regulations three months before the toll is opened to traffic.
Generally, the service life of inland river bridges is 50 to 60 years, and the main project of Hangzhou Bay Bridge has been raised to 100 years. According to Hong Kong standards, the design service life of the Hong Kong-Zhuhai-Macao Bridge is 120 years, which means that the service function can be fully met within 120 years, and it can be used safely without unplanned overhaul.
