Temburong Bridge

Temburong Bridge (Malay: Jambatan Sultan Haji Omar Ali Saifuddien) is located in Brunei Bay in the northeast of Brunei. It is 18.6 mi (30 km) long and has 4 lanes. It is one of the longest sea bridges in the world. It is longer than the Second Penang Bridge, the longest sea bridge in Southeast Asia before.

Construction of the bridge began in 2014 and will be officially opened to traffic on March 17, 2020. It spent 2.1 billion BND (US$1.6 billion). Its official name is Sultan Haji Omar Ali Saifuddien 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.

History

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.

• 1991: China and Brunei established diplomatic relations.
• September 2013: China announced the “One Belt One Road” initiative.

Construction

• 2014: Construction of Temburong Bridge started.
• February 2015: Daelim won the contract for the CC2 of the Tempurong Bridge. The company said it will build a 9.1 mi (14.6 km) cross-sea section with a construction period of 45 months.
• September 2015: Daelim won the CC3 contract. It contains 2 navigation bridges.
• October 1, 2015: China State Construction Engineering Corporation began construction of part of the bridge in the swamp.
• 2018: Brunei and China formed a strategic partnership.
• August 31, 2019: Dalin announced that the installation of the last girder of the Maritime Bridge has been completed.

• March 17, 2020: Due to the COVID-19 pandemic, the bridge opens ahead of schedule. After the completion of the bridge, the travel time in the two regions of Brunei has been reduced from 2 hours to about 25 minutes.
• July 14, 2020: The bridge is named Sultan Haji Omar Ali Saifuddien Bridge in memory of the Architect of Modern Brunei.

Building technical parameters

Temburong Bridge is 18.6 mi (30 km) long, and Length over water is 9.1 mi (14.6 km ). It is mainly composed of 1 9.1 mi (14.6 km) ocean viaduct, 2 channel bridges and 1 7.5 mi (12 km) swamp viaduct.

Ocean Viaduct and Waterway Bridge

The ocean viaduct is 9.1 mi (14.6 km) long and has 2 navigation bridges.

The navigation bridge with one main tower has a height of 351 ft (107 m); and the other navigation bridge with two towers has a height of 363 ft (110.5 m).

The ocean viaduct and two navigation bridges were constructed by Korea Daelim Corporation.

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.

Mentiri tunnel

This tunnel connects Jalan Utama Mentiri and Jalan Kota Batu in Brunei. The Mentiri 1 Tunnel is 2487 ft (758 m) long and the Mentiri 2 Tunnel is 1611 ft (491 m) long.
