Figures 59 and 60: Elevation and sections of the bridges
The two navigation channel bridges, namely Brunei
Channel Bridge (BCB) and Eastern Channel Bridge
(ECB) are crossed by cable stayed bridge. The BCB will
be a gateway between the Brunei-Muara and the
Temburong districts and is designed as an iconic
bridge. The ECB has a similar form. To cater for future
navigation needs of trade and navy vessels, BCB with
a single tower has a main span of 145m, Figure 59.
The ECB crosses the international waterway with a
main span of 260m between two towers, Figure 60.
The towers are crowned with the Islamic star and
crescent symbol.
Both bridges have a concrete ladder beam deck which
comprises of two edge girders and cross beams
between the edge girders, and concrete slab spanning
between the cross beams.
Brunei being an Islamic country, visually the concrete
towers have been designed to be unique and instantly
recognisable with qualities that incorporate Islamic
architectural features, Figures 61, 62 and 63.
In terms of engineering, the towers are A-shaped
towers, Figure 64, but visually look like an arched
gateway. The four architraves of the arch symbolise
the four districts of Brunei and the narrow slit window
on the top symbolises the unity of the four districts
with Koranic words at the apex of the arch.

As the project director for both the feasibility study
and detail design, and as the Engineer for all the civil
and M&E contracts, this project has given me
immense satisfaction to significantly contribute to the
development of Brunei and the opportunity to design
a bridge with Islamic features.
