US$1.17 billion bridge for Thailand island

A US$1.17 billion bridge is being proposed to connect Koh Samui Island with the Thai mainland. Construction of the bridge would boost transport to the island, which relies heavily on the tourist trade. The project is being put forward by the Expressway Authority of Thailand (EXAT).

Should the bridge project go ahead, it would connect Tambon Taling Ngam on the island with Tambon Thong Nien on the mainland. The proposed bridge will feature conventional box girder construction for part of its length, as well as a cable stayed section. A section of the bridge would be high enough to allow shipping to pass underneath and the structure would also feature protection to prevent damage from vessels.

Studies into the project to determine feasibility and environmental impact will be completed by 2026 and if the approval process is completed, construction would commence in 2029. The schedule would then see the bridge opening to traffic in 2033.

At present visitors to the island either have to fly there or use ferries. A new bridge would reduce journey times and boost tourism. The bridge would also help boost the island’s fishing industry.
