info:
Highways Department (HyD) of Hong Kong SAR is turning their idea for a world class bridge across
Rambler Channel at the entrance to Kwai Chung Container Port into reality. Due to the spectacular
location, HyD selected the concept for the bridge through an international design competition. The
competition took place in the first half of 2000 and the winning concept was a cable-stayed structure
with freestanding towers located between twin box girder decks. The 1018m main span is in steel,
while the four back spans each side are in concrete. The two towers stand on shore, providing
unobstructed access to the busy container port with a minimum navigation headroom of 73.5m.
A number of modifications were introduced to the scheme during subsequent technical review.
Detailed design started in March 2002. Tender was called in August 2003 and returned in December
2003. The construction contract was awarded to the Maeda-Hitachi-Yokogawa-Hsin Chong Joint
Venture, and construction began in April 2004. At the end of 2007, the concrete back spans were
complete and the towers were well on their way to their final heights of 298m forming significant
landmarks against the backdrop of Hong Kong harbour. Major sections of the steel deck, fabricated in
China, are now on site, with the areas around each tower erected by a 4000T heavy lift strand jacking
scheme. The first of the prefabricated parallel wire stay cables have been erected. Completion of the
bridge is scheduled for 2009.
