Changi was then revitalised with Changi Village and Somapah spruced up and Changi Airport being constructed in the area after land reclamation took place. However, this caused further disruptions to the livelihood of the residents as they had to make way for the airport and later the many other redevelopments in the area including high tech industrial estates. Finally in 1989, the last of New Zealand troops withdrew and all its remaining assets were handed over to the Singapore government. Redevelopment works continued into the 21st century with the progressive opening of the airport's terminal 3, 4 in 2008 and 2017, and the new Changi Prison Complex in 2004. Despite the strong progress of these developments, there were several ventures that were eventually stalled, like the Changi Motorsports Hub, which was expected to open as Singapore's first permanent motor racing circuit, but was halted in 2013.
