Marina Bay is a bay near Central Area in the southern part of Singapore, and lies to the east of the Downtown Core. An artificial bay, it was formed when land reclamation created the Marina Centre and Marina South areas, which form a body of sheltered waters of what was once open sea. In the reclamation process, Telok Ayer Basin was removed from the map, while the Singapore River's mouth now flows into the bay instead of directly into the sea. A barrage is currently under construction to make Marina Bay a reservoir for drinking water.
In contemporary local common usage, however, the term Marina Bay has largely been attached to the developments in the vicinity of Marina Mall in the Marina South reclaimed area, particularly to the eateries found there. Although technically erroneous, this association may have been stemmed from the association of the venue's limited accessibility to the Marina Bay MRT Station, which has served as the main means of public transport to Marina South.
It was announced in 2007 that Marina Bay will play host to a Formula One Race. The inagural Singapore Grand Prix will take place on September 28th 2008 on a street circuit through Marina Bay. It will be significant as it will be the first ever Formula One Grand Prix to be staged at night, with the track fully floodlit.
The new reservoir will provide another source of drinking water for Singapore, as well as a stable water level for a variety of water activities and events.
Future developments around Marina Bay are expected to further support Singapore's continuing growth as a major business and financial hub in the region. The area has also been planned to become a lifestyle hub and with 24/7 round the clock vibrancy and energy. It would consist of residential, office, and commercial developments, as well as many entertainment outlets and attractions to inject life into the area.
