How many kilometers is Hong Kong, Zhuhai and Macao: Revealing the magnificent engineering of the world’s longest cross-sea bridge
The Hong Kong-Zhuhai-Macao Bridge is a super project connecting Hong Kong, Zhuhai and Macau. It is known as the longest cross-sea bridge in the world. It is not only a symbol of China’s infrastructure strength, but also a miracle in the history of global transportation. This article will analyze the length, construction background, technical difficulties and social impact of the Hong Kong-Zhuhai-Macao Bridge, and present you with a structured data report based on hot topics in the past 10 days.
1. Basic data of the Hong Kong-Zhuhai-Macao Bridge

| Project | data |
|---|---|
| total length | 55 kilometers |
| Undersea tunnel length | 6.7 kilometers |
| bridge section length | 22.9 kilometers |
| Design service life | 120 years |
| total investment | About 126.9 billion yuan |
2. Construction background of the Hong Kong-Zhuhai-Macao Bridge
Construction of the Hong Kong-Zhuhai-Macao Bridge began in 2009 and took nine years before it was officially opened to traffic in 2018. It was born from the needs of the integrated development of the Guangdong-Hong Kong-Macao Greater Bay Area and aims to shorten the transportation time between the three places and promote economic cooperation. The completion of the bridge has shortened the drive from Hong Kong to Zhuhai and Macau from the original 3 hours to 30 minutes, greatly improving the efficiency of regional interconnection.
3. Technical Difficulties and Innovation Breakthroughs
The construction of the Hong Kong-Zhuhai-Macao Bridge faces a number of world-class challenges, including complex submarine geological conditions, a marine environment with frequent typhoons, and environmental protection requirements. Engineers used a number of innovative technologies:
| Technical difficulties | solution |
|---|---|
| Undersea tunnel immersed tube installation | Using the world's largest immersed tube tunnel technology, 33 sections of immersed tubes are accurately connected |
| Typhoon resistant design | It adopts a combination structure of cable-stayed bridge and suspension bridge, which can withstand Category 16 typhoons. |
| Environmental protection measures | Reduce the impact on the habitat of Chinese white dolphins and establish protected areas |
4. Correlation analysis of hot topics in the past 10 days
Recently, the Hong Kong-Zhuhai-Macao Bridge has become a hot topic again, mainly related to the following topics:
