Marina Bay is a bay near Central Area in the southern part of Singapore, and lies to the east of the Downtown Core. The area surrounding the bay itself, also called Marina Bay, is a 360 hectare extension to the adjacent Central Business District. Gardens by the Bay site is made up of Bay South Garden, Bay East Garden, and Bay Central Garden across the mouth of the Singapore River. All three gardens will be interconnected via a series of pedestrian bridges to form a larger loop along the whole waterfront and linked to surrounding developments, open public spaces, transport nodes and attractions.
