Singapore Changi Airport, one of the busiest international airports globally, is set to expand with the construction of a new Terminal 5. This expansion is part of the Changi East Development project and aims to address the airport's current capacity constraints. The facility processed over 58 million passengers last year, ranking it as the fifth-largest airport worldwide by international passenger numbers.
The development of Terminal 5 was initially announced in May 2013 by then Transport Minister Lui Tuck Yew. The project is supported by Singapore's Ministry of Transport, the Civil Aviation Authority of Singapore, and Changi Airport Group. However, due to the COVID-19 pandemic, plans were delayed for two years. In 2022, former Transport Minister S Irawan stated, "We have taken the opportunity of the two-year hiatus to comprehensively review the T5 design to make it more modular and flexible, and enhance its resilience and sustainability."
Construction is scheduled to begin in 2025 on a site covering over 1,080 hectares. The first phase will accommodate up to 50 million passengers annually. Upon completion in the mid-2030s, Terminal 5 will increase Singapore Changi Airport's capacity to over 153 million passengers per year.
