Marina Bay is abay located in theCentral Area ofSingapore, surrounded by the perimeter of four other planning areas, theDowntown Core,Marina East,Marina South andStraits View. The area surrounding the bay itself, also called Marina Bay, is a 360 hectare extension to the adjacentCentral Business District. It is also the new downtown ofSingapore, built on Singapore's reclaimed land.[1]
Buildings includeGardens by the Bay, theMarina Bay Sands,Marina Bay Financial Centre,Asia Square,The Sail @ Marina Bay and Marina One integrated mixed-use developments. It is one of the key focus areas by theUrban Redevelopment Authority. Marina Bay is envisioned by the URA as a work-live-play vibrant 24-hourCBD.
The Marina Bay is afreshwater bay at the confluence of four rivers: theSingapore River,Kallang River,Geylang River, andRochor River.
TheUrban 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. Thereclaimed land forms what is today theMarina Centre andMarina South areas, and the reclamation work was completed in 1992.[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 theSingapore River's mouth now flows into the bay instead of directly into the sea.
The long term visions for the Marina Bay area were first articulated in the 1983 Master Plan by theUrban Redevelopment Authority (URA), with the waterfront areas being deliberately kept open to the public.[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. In 2005, the Urban Redevelopment Authority spent $400,000 on a branding exercise to name the Marina Bay area in order to sell the new major developments in the area, only to settle with the original name "Marina Bay".[6][7]
The Singapore government also spent $35 million to complete the 3.5 km Waterfront Promenade around Marina Bay.[8] It includes a new eco-friendly visitor centre and theHelix Bridge linking Bayfront to Marina Centre where theYouth Olympic Park is located. The Promontory @ Marina Bay (formerly Central Promontory Site) will be used as an interim event and public space used for activities such as theatres and carnivals.[9]
In 2008,Marina Barrage was built, converting the basin into a freshwater Marina Reservoir.

TheFormula OneSingapore Grand Prix has taken place annually since 2008 (with the exception of the2020 and2021 seasons) on astreet circuit adjacent to Marina Bay.[10] Since its construction in 2007,The Float@Marina Bay has hosted events such as theNational Day Parade, New Year's Eve Countdown[11] andSingapore Fireworks Celebrations, and also serves as a spectator stand for the Singapore Grand Prix. Furthermore, it also played host to the Opening and Closing Ceremonies of the inaugural2010 Summer Youth Olympics.[12]
The area also hosts the annuali Light Marina Bay, a sustainable light art festival.
The event space next to Marina Bay Sands, known as The Lawn, hosted the first overseas and Singapore edition of ArtBox Bangkok on two separate weekends, 14–16 April and 21–23 April 2017.[13][14]

The Singapore government pumped nearly S$2 billion (about US$1.2 billion) to build the infrastructural base for Marina Bay, which includes theMarina Barrage, increased connectivity to theMRT, and the newMarina Promenade andHelix Bridge.[citation needed]
The Common Services Tunnel is a development of the Marina Bay area in Singapore. It is said to be the second of its kind in Asia afterJapan. Thisutility tunnel houses telecom cables, power lines, water pipes as well as provision for pneumatic refuse collection pipes.[15] The 1.4-kilometre (4,600 ft) phase one of the tunnel has cost aboutS$81 million (aboutUS$51 million) while 1.6-kilometre (5,200 ft) phase two, cost around S$137 million (about US$86 million).
SP Group's subsidiary, Singapore District Cooling, started operating Singapore's firstdistrict cooling plant, supplying chilled water supplies toOne Raffles Quay in May 2006.[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. Built at a cost of some S$110 million (about US$69 million), the second district cooling plant will be able to serve 1.25 million square metres of gross floor area and free up space which should be used for building chiller plants and cooling towers for separate buildings. The second district cooling plant started operations on 3 March 2016.[17]
In 2004, thePublic Utilities Board announced plans to construct a new downtown reservoir by damming theMarina Channel. This barrage was completed in 2008. Known as theMarina Barrage, it turned Marina Bay and theKallang Basin into a confined freshwater reservoir with limited access to marine transportation to regulate the water quality. The new reservoir provides another source of drinking water for Singapore, as well as a stable water level for a variety of water activities and events. The barrage also prevents flooding in theChinatown area.
There are currently eight rail stations:City Hall,Raffles Place,Marina Bay,Bayfront,Downtown,Telok Ayer,Esplanade andPromenade serving Marina Bay. 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.[18] The first two new MRT lines (Circle line,Downtown line) opened between 2012 and 2013. By 2018, the Marina Bay district had more than sixMRT stations, all no more than five minutes of each other. TheThomson–East Coast MRT line created better connections within Marina South, opened in 2022. Apedestrian network links developments andMRT stations.[19] Within greater Marina Bay, water taxis will even double up as an alternative mode of transport.
