Temburong Bridge, Brunei – Design of CC1 Tunnels and Bridges in Mentiri

Abstract

<p>The new 30 km Cadangan Projek Jambatan Temburong (Temburong Bridge Project) in Brunei will connect the relatively isolated district of Temburong with the more developed Brunei-Muara district. The project includes approximately 3.6 km in Brunei-Muara district where the new road will pass through the Mentiri hills. This section will be built under Construction Contract CC1 and includes 3 twin-bore lengths of tunnel and various bridge structures. Design is to Eurocode.</p><p>The tunnels are in hard soils / weak rock and will be the first mined tunnels to be built in Brunei. The tunnel portals incorporate Islamic shapes to continue the architectural theme of the project.</p><p>Bridges will link the different tunnels together and form the free-flow connections to an existing dual carriageway at the north-west end of the scheme.</p>
