The Urban Redevelopment Authority (URA) Master Plan for Marina Bay aims to encourage a mix of uses for this area, including commercial, residential, hotel and entertainment.

In 1954, land reclamation work to create 360 hectares of prime waterfront site began at Marina Bay.

[2][3][4] In the reclamation process, Inner/Outer Basins (anchorage area for commercial and naval vessels), Telok Ayer Basin (now site of Asia Square Tower 1 and 2) and Inner Roads was removed from the map by reclaiming land, while the Singapore River's mouth now flows into the bay instead of directly into the sea.

[2] In 1988, the draft plan for Marina Bay was presented to the public in a two-week exhibition where it set out the objectives for the development, among which are optimising the waterfront location and creating a distinctive image with international landmarks that could become a focal point for the city.

[5] The URA Master Plan for Marina Bay aims to encourage a mix of uses for this area, including commercial, residential, hotel and entertainment and to turn it into a work-live-play vibrant 24-hour CBD.

The Formula One Singapore Grand Prix has taken place annually since 2008 (with the exception of the 2020 and 2021 seasons) on a street circuit adjacent to Marina Bay.

[16] A second district cooling plant was commissioned in May 2010,[16] which will supply chilled water for the air-conditioning of buildings in the area through pipes housed within the Common Services Tunnel, according to the report.

[17] In 2004, the Public Utilities Board announced plans to construct a new downtown reservoir by damming the Marina Channel.

As the plan set out, by 2020, the 360 hectares of Marina Bay boasts a comprehensive transport network as Singapore's most rail-connected district.
