Construction—APAC—Brunei—Bridges DYWIDAG Strand Tendons for flowing Road Traffic: New Viaducts in Brunei In the sultanate of Brunei on Borneo Island, 57 new road construction projects will be built that will provide for more safety in road traffic and ease congestion on the existing roads. This also includes a new flyover in the district of Gadong in the country’s northeast that is located 5km from the capital Bandar Seri Begawan. Thanks to the new bridge at the Jalan Gadong/Jalan Telanai Junction, traffic will flow uninterrupted on Jalan Gadong Road. In addition, a new set of traffic lights will be installed for right-turning vehicles at Jalan Telanai Road. The flyover is a three-span bridge consisting of 27m + 36m + 27m spans. 13, 36m long prestressed precast concrete (PSPC) I-girders 46 and 26, 27m long PSPC I-girders were required for the spans.
