Installation of Double-Arch Steel Bridge Across Hong Kong’s Tseung Kwan O Bay Completed

On February 26, the installation of the double-arch steel bridge, the largest prefabricated component of the Tseung Kwan O Cross-Bay Link, was completed.

As the double-arch steel bridge weighs more than 10,000 metric tons, engineers used the "float method" to coordinate with the tide to install it. The entire process lasted nearly 5 hours. This is the first time that Hong Kong has used the "float method" to build a bridge.

The Tseung Kwan O Cross-Bay Link has a total length of approximately 1.8 kilometers, including a 1-kilometre-long sea viaduct. The project is scheduled to be completed in 2022.



Shiziyang Passage Project Commences Survey and Design

Recently, one of the core projects in the Guangdong-Hong Kong-Macao Greater Bay Area, the Lion Ocean Passage, completed the survey, design and consultation bidding, marking the entry of the project into a new stage of survey and design.

The Shiziyang Passage adopts the technical standards of a two-way eight-lane expressway with a design speed of 100 km/h, and the roadbed width is 41.5 meters. For the Shiziyang Passage Main Bridge across the river, it is recommended to adopt a super-long-span suspension bridge with a main span of 2,180m and a double-layer 16 (upper 8 + lower 8) lane highway technical standards.

Dafaqu Bridge on Renzun Expressway Starts Hoisting

A few days ago, the main control project of Renzun Expressway-Dafaqu Bridge, passed the inspection and acceptance of the expert group, and is about to enter the stage of section hoisting.


It is understood that the Dafaqu Bridge (formerly known as Tuanjie Bridge) is a large-span steel tube concrete arch bridge with a total length of 1,427 meters, a main span of 410 meters, and a bridge width of 33 meters. It flies across Zunyi and Renhuai, and the main bridge port is above the ground. With a maximum vertical height of 75 meters, it is one of the main control projects of Renzun Expressway. After completion, it will become the largest bridge of the same type in the world. By then, it will only take half an hour from Zunyi to Renhuai, and 20 minutes from Tuanjie Village to Zunyi. This two-way, six-lane urban and rural "main artery" will effectively promote tourism development along the route and boost rural revitalization.
