A new, mega Terminal 5 will be ready by the middle of next decade at Changi East and have the capacity to handle 50 million passenger movements a year - larger than T2 and T3 combined.

Minister of State for Transport Josephine Teo unveiled plans for Changi Airport at a briefing on Friday afternoon. The future T5 will be linked to other airport terminals via underground tunnels so the expanded Changi Airport can be operated as a single, integrated airport with easy transfers between terminals, maximum convenience for passengers and efficient airfield operations.

Changi currently has three terminals, two runways and can handle 66 million passenger movements a year. By around 2020, it will have four terminals, three runways and be able to handle 85 million passenger movements annually. T5 will up Changi's handling capacity to 135 million passenger movements. Space will also be set aside for future satellite terminals if additional capacity is required.

The road infrastructure around Changi will be improved to ensure convenient access to T5, which will also be connected to the MRT network. The adequacy of bus services to the airport will also be reviewed.

The existing Changi Coast Road and park connector beside it will be replaced with a new road and park connector further east along the eastern coastline, to make space for a continuous and integrated airfield.
