The two bridges will connect Sungai Kolok and Takbai districts in Narathiwat with Malaysia’s Kelantan state. The project was proposed by then Deputy Prime Minister Gen Prawit Wongsuwan, who is now acting Prime Minister.The first bridge - Sungai Golok-Rantau Panjang Bridge - with six traffic lanes will be built parallel to the existing bridge in Sungai Kolok district, which is too narrow for large vehicles and cannot be expanded.
The second one will connect downtown Takbai of Narathiwat province with the Malaysian town of Pengkalan Kubor as part of an 11-kilometre road with 4-6 traffic lanes.
Ratchada said a Malaysian working group will arrive in Thailand in December to study the construction of a road from the new Sadao checkpoint in Songkhla province to the Bukit Kayu Hitam checkpoint in Malaysia’s Kedah state.
