Koh Lanta Bridge

Koh Lanta Bridge is a proposed bridge connecting Koh Lanta to the Krabi Province mainland in Thailand. The bridge would span 1,950 metres from Ban Hua Hin (at the Hua Hin Pier) to Ko Lanta Noi. It would be a two-lane suspended bridge with a bicycle lane on both sides.

Ko Lanta is a district comprising several islands in Krabi province. The islands resemble a peninsula that has been cut off from the mainland, similar to Phuket. The Sarasin Bridge that connects Phuket to the mainland is 660 metres, so the proposed Lanta bridge would be three times that length.

The two main islands of Koh Lanta (Ko Lanta Noi and Ko Lanta Yai) are connected by the Siri Lanta Bridge (sometimes called the Koh Lanta Bridge). This bridge was completed in April 2016. The new Koh Lanta Bridge would enable vehicles to travel from the mainland to the popular tourist areas in Ko Lanta Yai.

The most recent update said that a budget will be requested in 2022. If approved, construction will commence in 2023 with a completion date of 2025.
