The Department of Highways (DOH) has announced a 20-year roadmap to expand Thailand’s highway network, including the construction of new motorways. In line with this, the agency has also contracted companies to conduct feasibility studies for the updated Motorway-Rail Map (MR Map). Results from the study, which will explore possibilities for developments for future highways and transportation, will be presented to the Ministry of Transport (MOT) for review before the end of 2023.

As per the study’s recommendations, around nine projects, with a combined cost of THB457 billion, will be developed in the first five years of the plan. Around 331 km of new highways will be constructed under this phase. DOH also plans to develop THB775.9 billion worth of new motorways in subsequent phases of the plan.

Development of the projects under the MR Map will be overseen by multiple agencies under the MOT, including the Expressway Authority of Thailand (EXAT), the State Railway of Thailand (SRT), and the DOH.
