Longest bridge in Southeast Asia

Sultan Haji Omar 'Ali Saifuddien Bridge is a dual-carriageway bridge in Brunei. It is the longest bridge in Southeast Asia, 30 kilometres (19 mi) long. The construction cost is reported to 1.6 billion Brunei dollars. Construction on the bridge started in 2014 and opened during March 2020. The bridge connects Mengkubau and Sungai Besar in Brunei-Muara District with Labu Estate in Temburong District. This is the only road bridge in the country that directly links the mainland with the Temburong exclave, which are physically separated by the Sarawakian district of Limbang in Malaysia and Brunei Bay in the South China Sea. The bridge allows commuters to travel between the two territories without having to go through Malaysia, bypassing four immigration checkpoints along the mainland route and shortening travel times between Temburong and the capital Bandar Seri Begawan.
