Thailand infrastructure development is reshaping the country beyond Bangkok, fostering economic expansion in secondary cities. By prioritizing regional investments, the government aims to bridge urban-rural disparities and create new economic hubs.
Thailand infrastructure development is also enhancing nationwide connectivity through strategic transport and smart city initiatives. These efforts are positioning Thailand as a leading economic player in Southeast Asia, attracting global investment and innovation.
Transport Initiatives

The government is advancing infrastructure development with a focus on high-speed and double-track railways. These projects, particularly in the Eastern Economic Corridor (EEC), will connect major airports and industrial zones. In addition, the Khon Kaen urban rail network marks the first regional rail system outside Bangkok.

As part of infrastructure development, U-Tapao International Airport in Rayong is undergoing a major expansion. By 2029, it is set to accommodate up to 60 million passengers annually, strengthening the EEC’s role as a logistics hub.
Seaport Developments
Thailand infrastructure development in maritime transport includes the expansion of Laem Chabang Deep Seaport (Phase 3) and Map Ta Phut Industrial Port (Phase 3). These projects aim to increase cargo capacity and enhance Thailand’s global trade competitiveness.
