The Ministry of Transport (MoT) of Thailand has announced plans to develop a dual-track railway network and a new motorway to improve connectivity between Hat Yai and the Sadao border checkpoint.
The State Railway of Thailand (SRT) is preparing to seek cabinet approval for three railway expansion projects: a 168-km Chumphon-Surat Thani route (THB30.4 billion), a 321-km Surat Thani-Hat Yai-Songkhla route (THB66.27 billion), and a 45-km Hat Yai-Padang Besar route (THB104.46 billion). Additionally, the SRT plans to seek 2025 budget funding for a 216-km Songkhla-Sungai Kolok-Narathiwat route, set to open in 2034.
The ministry is also considering investment for the M84 motorway, a THB40.78 billion baht project connecting Hat Yai to the Malaysia border, with construction expected between 2027 and 2030. The government is also progressing with a 9.3-billion-baht Hat Yai bypass project to ease traffic congestion.
