I. Brunei Temburong Bridge
Brunei is located on the north coast of the island of
Borneo. Apart from its coastline on the South China
Sea, it is completely surrounded by the Malaysian
State of Sarawak, and since 1890 it has been
separated into two parts by Sarawak, Figure 56.
and supervise the construction of the dual 2-lane
expressway link with a total length of approximately
30km between Muara district and Temburong District,
Figure 57.
Figure 57: Components of the Link
The link comprises of approximately 3km of tunnels
and viaducts in Muara, 14km of marine viaduct across
Brunei Bay, two navigation channel bridges and 12km
of low height viaduct across the mangrove and swamp
forest in Temburong.

The physical separation of Temburong District from
the majority of Brunei has significantly affected the
e conomic development of Temburong and Brunei as a
whole. The travel to Temburong from the capital
Bandar Seri Begawan (BSB) by land requires passing
into and out of Sarawak with a journey time that can
take up to four hours.
The alignment across Brunei Bay is in an S-curve to
give interesting views of the navigation channel
bridges and the varying coastline, Figure 58.
Alternatively it is possible to travel by speedboat
across Brunei Bay with very limited capacity. Neither
of these alternatives offers 24 hour a day accessibility.
In 2010 following a selection process, Arup were
appointed by the Public Works Department (PWD) as
the consultant to undertake a comprehensive socio-
economic and engineering feasibility study to provide
a fixed link between BSB and Temburong.
The conclusion of the study was that the project is
technically feasible, economically viable and that the
environmental impacts can be managed or mitigated.
PWD then appointed Arup to carry out the final design
