Which is the largest sea-crossing bridge in the world?

As of September 2023, 13, the largest sea-crossing bridge in the world is the Zhuhai-Hong Kong-Macao Bridge.

Hong Kong-Zhuhai-Macao Bridge is a sea-crossing bridge with the longest mileage, the longest immersed tunnel, the longest service life, the largest steel structure, the most difficult construction, the highest technical content, and the largest scientific and technological patent and investment amount in the world. The technology and equipment scale of bridge engineering have created many world records.

On April 28th, 2023, Zhuhai Highway Port of Hong Kong-Zhuhai-Macao Bridge ushered in the peak of entry and exit vehicles, and the daily inspection volume exceeded 9,000 vehicles for the first time, setting a new record of 8,320 vehicles on April 16.

The Hong Kong-Zhuhai-Macao Bridge starts from the artificial island in Hong Kong near the Hong Kong International Airport in the east, crosses the Lingdingyang waters in the South China Sea in the west, connects the artificial islands in Zhuhai and Macao, and ends at the Hongwan Interchange in Zhuhai. The total length of the bridge and tunnel is 55km, of which the main bridge is 29.6km and the Hong Kong-Zhuhai-Macao port is 41.6km. The bridge deck is a two-way six-lane expressway with a design speed of100km/h..

Construction significance:

The completion and opening of the Hong Kong-Zhuhai-Macao Bridge is conducive to personnel exchanges and economic and trade exchanges between the three places, to the development of Guangdong-Hong Kong-Macao Greater Bay Area, to the comprehensive competitiveness of the Pearl River Delta region, to supporting the integration of Hong Kong and Macao into the overall situation of national development, and to comprehensively promoting mutually beneficial cooperation between the mainland and Hong Kong and Macao.

We must adhere to the people-centered development concept, provide first-class operation services based on first-class bridges and first-class ports, and build the Hong Kong-Zhuhai-Macao Bridge into a "popular bridge" connecting Guangdong, Hong Kong and Macao.

It is necessary to further simplify the approval process, shorten the customs clearance time, and build the Hong Kong-Zhuhai-Macao Bridge into a link between Hong Kong, Macao and the mainland for collaborative innovation and integrated development. It is necessary to transform the key technologies of engineering construction into industry standards and norms, and build the Hong Kong-Zhuhai-Macao Bridge into a beautiful business card for Chinese bridges to "go global".
