Overview Temburong Bridge
Overview Temburong Bridge

This is the country’s first road bridge directly connecting mainland Brunei and Temburong. It connects Sungai Besar and Mengkubau. The bridge allows commuters to travel between the two territories without having to cross Malaysia, thus bypassing the four immigration checkpoints on the current route that is often crowded.


Birth background

Brunei declared to be a completely independent country on January 1, 1984, and joined the United Nations in September, becoming the 159th member state.

The territory of Brunei is divided into two parts, separated by Sarawak State in Malaysia and the Bay of Brunei. Traffic problems have seriously hindered Brunei’s economic development. Brunei urgently needs a bridge across the Brunei Bay to connect the country as a whole.

Swamp viaduct

The swamp viaduct is 7.5 mi (12 km) long and was built by China State Construction Engineering Corporation. The bridge crosses the swamp forest in the Temburong area. The CC4 part is completely constructed with environmental protection technology, which prevents the mechanical equipment from touching the ground and does not damage the rainforest vegetation, making the construction difficult.
