Construction of a 490m dual 3-lane expressway road bridge
comprising 2 spans of 65m and 3 spans of 121m; and 1479m
of viaducts and access roads, linking the Cheung Ching
Tunnel at its western extremity. The bridge is part of
the link between the Chek Lap Kok airport, Kowloon and
Hong Kong Island.
Technical
information:
The bridge was built by the balanced cantilever method,
using a launching girder to install the pre-cast segments.
This technique allowed a reduction in the construction
programme as well as causing minimal diruption to marine
traffic during construction. It is also the first bridge
in Hong Kong to use external pre-stressing, a feature
whcih substantially redues maintenance costs.
