Marina Bay is a bay located in the Central Area of Singapore surrounded by the perimeter of four other planning areas, the Downtown Core, Marina East, Marina South and Straits View. The area surrounding the bay itself, also called Marina Bay, is a 360 hectare extension to the adjacent Central Business District.
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.
The Singapore government also spent $35 million to complete the 3.5 km Waterfront Promenade around Marina Bay. It includes a new eco-friendly visitor centre and The Helix linking Bayfront to Marina Centre where the Youth 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.
