Thailand's Transport Infrastructure Development Master Plan, 2015-2022 plans to invest B1.9 billion ($54 million) in the sector. Among its big-ticket projects are upgrading the country's rail network, building a double-track railway to the border with the Lao PDR, building four-lane highways connecting growth centers with border areas, extending Bangkok's metro rail transit, and building seaports on the Gulf of Thailand and the Andaman Sea.
As well as the master plan, Thailand launched an annual Investment Action Plan in 2015: that year's plan had 59 projects totaling B848 billion ($24.0 billion). Of this, B56 billion ($1.6 billion) was disbursed in 2015, with the rest to be spread up to 2022. The action plan for 2017 has 36 new projects and seven continued projects from the 2016 plan. The 36 projects, worth B905 billion ($25.6 billion), are all in transport and include 10 double-track rail network projects, five motorway and expressway projects, and three projects each for maritime and air transport. The government expects all the projects in the 2017 action plan to be financed through loans (65%); PPPs (26%); the budget (6%); the Thailand Future Fund, a government infrastructure fund (2.5%); and SOEs (0.2%).
