Temburong Bridge

Temburong Bridge

Temburong Bridge, also known as Sultan Haji Omar Ali Saifuddien Bridge, is located in Brunei Bay in the northeast of the country. With a length of 30 kilometers and four lanes, it is one of the world’s longest sea bridges.

The bridge connects Sungai Besar and Mengkubau. It allows commuters to travel between the two territories without crossing Malaysia, avoiding the four immigration checkpoints on the current route, which is frequently congested.

Dextra involved in this project by supplying 34,000 linear meters of Sonitec tubes for the integrity testing of foundation piles using the CSL (crosshole sonic logging) testing method.

Construction of the bridge began in 2014 and was officially opened to traffic in 2020.
