The track then goes onto the Anderson Bridge, past the Fullerton Hotel and make a tight left turn to Esplanade Drive beside the Merlion Park.

The track was widely criticised by F1 drivers for being excessively bumpy, particularly on Raffles Boulevard between turns 5 and 7, resulting in a very unforgiving circuit, especially given the hot and humid conditions of the Singapore climate.

[13] Several drivers, including Sébastien Bourdais and Fernando Alonso, expressed their concern about the high and harsh kerbs at the chicane at turn 10 of the street circuit.

The chicane at Turn 10 was reprofiled for the 2010 race in an attempt to make it safer and the turns more gradual by moving the kerbs, however Lewis Hamilton said in an interview this modification made the chicane more dangerous by making the entry to the corner smaller, calling the complex "the worst corner in F1".

[18] The problem was deemed to be primarily due to the speed differential of those entering the pits and those continuing on another lap and their sharing of the same race line.

As a safety measure to compensate for the higher speeds, an extra layer of TecPro barriers were added to the end of the Turn 10 run-off.

[17] In 2015, the FIA approved minor changes to the layout of the Marina Bay Street Circuit ahead of the 2015 Singapore Grand Prix.

In August 2020, Singapore Prime Minister Lee Hsien Loong announced plans to redevelop the Marina Bay Floating Platform into a community space centred on the city-state's policy of National Service.

[23] The floating platform has housed the Turn 16–19 series of corners since the circuit's inception in 2008 and is expected to make way for the construction of NS Square in 2022.

[27] For the purpose of the night race, approximately 1600 custom-made floodlights are spread around the 5.067 km (3.148 mi) Marina Bay circuit.

The lights, four times brighter than at a regular sports stadium, are specially designed to minimize glare and surface reflection, and to meet F1's TV broadcasting standards.

On Raffles Boulevard (where the second DRS zone is located), flat-out for turn 6, to the fastest part of the circuit at speeds of up to 320 km/h (200 mph).

The car is now at Esplanade Bridge (where the third DRS zone is located) crossing the Singapore river, building up speed to 290 km/h (180 mph).

Following a reprofiling before the 2023 Singapore Grand Prix, a long straight on Raffles Avenue (where the fourth DRS zone is located) replaces turns 16–19, bypassing the technical Float section.
