Figure 30: Temporary trestle bridge
The mono inclined towers of the cable stay bridges
are in concrete with a rectangular cross-section and
taper towards the top, Figure 31.
The box girder of the back span was lifted into
position with the aid of strand jacks, whilst the main
span deck was cantilevered out with segments lifted
from a delivery barge, Figures 32 and 33.
For me as the Project Director the design of Shenzhen
Bridge was a good and instructive experience of
working with Chinese consultants and authorities with
different cultural outlook, but it showed that the
common language of engineering and architecture
can bridge the cultural differences in a constructive
manner.
With the shrinking world big bridges there is going to
be ever increasing collaboration between consultants
and contractors with diverse backgrounds and
Shenzhen Bridge has helped me in subsequent
projects like the Hong Kong Zhuhai Macao Bridge to
work with designers with different cultures.
Figure 31: Inclined tapering tower
The decks with main spans of 210m and 180m are
multi-celled steel orthotropic box girders with the stay
cables aligned along the centre line of the box girders.
