Service 400 serves the Marina South and Marina Coastal area with connections to Marina Bay MRT, Downtown MRT and Shenton Way. Before the mass redevelopment of Marina South, much of the area was a park and Service 400 provided the bus connections needed. In recent years, the construction of the Circle Line Extension and Downtown Line have diminished the role of Service 400 as a crucial connecting route in the Marina South area; however it still receives demand from shuttling passengers between Tanjong Pagar, Downtown and Marina Bay MRT stations to the Marina Barrage and Gardens by the Bay (Bay South).
With the route integration with Service 402 in June 2019, Service 400 now serves Marina South Pier MRT Station as well as Marina Bay Cruise Centre.
Formerly designated as a Parks service in 2005 (serving Marina City Park and Marina Padang), it was reverted back to a normal trunk route in 2009.
During New Year’s Eve, operating hours will be extended. Exact last bus hours are announced by SBS Transit closer to the day.
