Main Bridge of Tseung Kwan O Cross-Bay Closed Ahead of Schedule

On December 30, after 4 consecutive days of lifting construction, the superstructure of the Hong Kong Tseung Kwan O Cross-Bay Link Bridge was completed. The main bridge was closed ahead of schedule, and the construction of the project ushered in another important milestone.

Main Bridge Before Closure


Frank Chan, Director of the Transport and Housing Bureau of the Hong Kong Special Administrative Region Government, and Michael Leung, Project Manager of the East Development Office of the Civil Engineering and Development Department, witnessed the lifting process on-site. Frank Chan congratulate the closing of the main bridge of the project and praised the unity of the project team for overcoming difficulties and advancing the construction of the project. He hoped that everyone could continue to maintain this good momentum, complete the construction of the bridge as soon as possible, and present another high-quality project to the citizens of Hong Kong.

 Main Bridge After Closure


The segmental box girder installed this time is prefabricated off-site by the short-line method, with an average length of 2.8 meters and a weight of 53 tons. In order to speed up the installation progress and maximize the advantages of prefabricated construction, the project team innovatively proposed the construction method of "full-span lifting of prefabricated segmental girders" after detailed study, that is, the individual prefabricated segment will be connected by pre-stressed tendons in the fabrication yard to form a full span, and then transported to the installation site as a whole, and a large crane barge will be used to carry out the full-span lifting. This method shortens the installation period of the segments from 16 days to less than half a day, greatly reduces the amount of on-site offshore operations, and reduces construction risks and the affects to surrounding residents.

Xinhua News Agency reported on the closing of the Tseung Kwan O Cross-Bay Bridge Project on December 30.
