Relocation of Paya labar airport
Opened on Aug 20, 1955, to replace the old Kallang Airport, the Paya Lebar Airport became a base of the Republic of Singapore Air Force when Changi Airport opened in 1981.
A new air base and a fourth runway will be built at Changi East, with the Paya Lebar Air Base to be moved to Changi.
The move will not only free up a large 800 hectare area in Paya Lebar X an area bigger than Bishan or Ang Mo Kio X for new homes, offices, factories and parks, it will also remove height restrictions on a large area around Paya Lebar. Based on HDBs latest update in 2011, Ang Mo Kio has about 49,000 flats under its management.
