Marina Bay
4.927 km of downtown streets, raced at night under floodlights in tropical heat. Singapore's street circuit has 19 corners, walls everywhere and one of the most physically demanding races of the year. Learn how the lap works, then open it in the designer and make your own version.
The track at a glance
The Marina Bay Street Circuit runs on public roads around Marina Bay in the centre of Singapore. The current layout is 4.927 km long with 19 turns, runs anticlockwise, and a Grand Prix there is 62 laps.
When it opened in 2008 it hosted the first night race in Grand Prix history. Around 1,600 custom floodlights light the track, and the cars race past the city's colonial waterfront, across a historic bridge and under the main grandstand.
It is one of the toughest races of the year for drivers. The heat and humidity stay high even at night, the track is bumpy with walls close on every side, and there is little time to rest between corners. The current contract runs until 2028.
A lap of Marina Bay, corner by corner
Only some of the 19 turns have names, so this guide follows the key corners by their official numbers. The numbers match the map.
- T1Sheares. A left-hander at the end of the pit straight, named after Benjamin Sheares, Singapore's second president. It starts a tight left-right-left sequence and is a good place to pass on the first lap.
- T3Onto Republic Boulevard. A slow left that opens onto Republic Boulevard. A clean exit matters for the long, curving run that follows.
- T7Memorial. A 90° left at the end of the long run down Raffles Boulevard, named after the nearby Civilian War Memorial. It is the main overtaking spot of the lap.
- T10The old Singapore Sling. Once a slow, unpopular chicane, it was replaced in 2013 by a flowing left-hander taken about 40 km/h faster.
- T12Anderson Bridge. The track crosses the historic Anderson Bridge, a narrow section where the walls feel very close.
- T13The waterfront hairpin. A slow left-hand hairpin by the colonial waterfront, widened by a metre in 2015. It leads onto the straight along Esplanade Drive.
- T14Esplanade braking zone. A right-hander at the end of Esplanade Drive and another chance to overtake.
- T19The final corner. The last left onto the pit straight. Since 2023 the end of the lap has been faster, after a straight replaced four slow corners.
How the layout has changed
The circuit has been tweaked almost every few years, mostly to make it faster or to make room for building work around the bay.
- 2008The circuit opens and hosts the first night race in Grand Prix history.
- 2013The Singapore Sling chicane at Turn 10 is replaced by a faster left-hander.
- 2015The track switches to the other side of Anderson Bridge, and the Turn 13 hairpin is widened.
- 2022A new deal keeps the Singapore Grand Prix on the calendar until 2028.
- 2023A straight past the Float at Marina Bay replaces four slow corners near the end of the lap.
Why it is so hard
Street circuits squeeze a race track into roads that were built for everyday traffic. At Marina Bay that means 90° junction corners, kerbs, bumps and walls right at the edge of the track. Drivers can't use run-off to recover from a mistake, so the race often brings safety cars.
The night-time heat adds to it. The cars are lapping through a tropical evening, and the race often runs close to its two-hour time limit. For more on street-circuit design, read Designing Monaco from scratch or our guide to how wide a race track is.
Ideas for your remaster
The Remaster button opens the traced layout in the designer. You can move any point and the lap time, speed trace and corner analysis update as you go. A few places to start:
Make it easier to pass. Try a longer run into Turn 14, or a tighter Turn 7, and watch the braking zones in the speed trace.
Bring back the old ending. Before 2023 the lap finished with a slow, twisty section. Add it back in and compare the lap times.
Name the corners. Most of Marina Bay's corners only have numbers. Group and name them in the designer, and they'll show on your exports and share link.
Finish it properly. Add track width, kerbs, run-off and a pit lane so it reads like a real venue.
When you're happy with it, share your version with its own link. The original stays here for the next person to remaster.
Frequently asked questions
How long is the Marina Bay Street Circuit?
The current layout is 4.927 km (3.061 miles) long with 19 turns. A Grand Prix there is 62 laps.
Why is the Singapore Grand Prix held at night?
Racing at night avoids the worst of the tropical daytime heat and suits European television audiences. When it opened in 2008 it was the first night race in Grand Prix history.
Which way does the Singapore circuit run?
Anticlockwise. From the pit straight the lap heads through Sheares and along Raffles Boulevard to Memorial, crosses Anderson Bridge, and returns along the bay to the final corner.
What changed in 2023?
A straight replaced four slow corners near the end of the lap, making the final sector much faster.
Is the remastered Singapore an exact copy?
It is a close trace of the centreline using 66 editable points, within a few metres of the real layout. Track width, kerbs, run-off and the pit lane are left for you to design.
