The Tuas area in the early nineteenth century was
referred to by three place names: Tg
Kampong, Tg Rawa and Tg
Gull — references made in Franklin and Jackson's
1830 map of Singapore.
Tuas used to be swamp land which was
later cleared for squatter settlement.
It became a fishing village. In
the old days, it was not unusual to see about 200 fishing boats in
Tuas every morning.
In the 1970s, the residents in Tuas were resettled
in public
housing estates. Tuas was then developed for industrial use. In
the 1980s, land was reclaimed around
Tuas for more industrial development. By 1988, about 6.5 km² of
land off Tuas were reclaimed. Land
reclamation off Tuas is still ongoing; the land area of
Tuas will increase from 17.02 km² in 1996 to the projected 20.75
km² by 2010 [1]. PentaOceanConstruction
(五洋建設)is most heavily involved in the land reclamation. The
peninsular reclaimed in the late 1980s to early 1990s is
named Tuas South, while the land currently
being reclaimed to the southeast of Tuas
Jetty is known as the Tuas South
Extension.
