Thailand’s Ministry of Transport has prepared a pipeline of 11 major infrastructure megaprojects with a combined value of THB359.8 billion, which are expected to be submitted for Cabinet approval in 2026 once a new government is in place. The programme is positioned as a key economic stimulus tool, targeting job creation and construction-sector activity amid political transition and delayed approvals for long-term budget commitments.
The proposed projects span three core segments. Road and expressway developments account for six projects, including the Nakhon Pathom–Cha-am Motorway (M8), the Phuket Expressway, and several strategic junction and ring-road links around Bangkok. Rail investment focuses on three double-track railway sections under Phase 2 of the national programme—Chumphon–Surat Thani, Surat Thani–Hat Yai–Songkhla, and Hat Yai–Padang Besar—worth a combined THB101.25 billion and led by the State Railway of Thailand.
Aviation forms the third pillar, with THB90.66 billion earmarked for capacity expansion at four major airports: Suvarnabhumi, Don Mueang, Chiang Mai, and Phuket. These upgrades aim to support tourism recovery and long-term passenger growth. Beyond the 11 projects, the ministry is also seeking policy direction on stalled initiatives, including the high-speed rail linking Don Mueang, Suvarnabhumi, and U-Tapao airports, and advancing the Southern Economic Corridor under the Land Bridge initiative, which carries an estimated investment of nearly THB990 billion.
