Circuit changes to accommodate spectators

Earlier this year, Singapore GP’s deputy chairman Colin Syn announced changes to the stretch from Turn 11 to Turn 13 to help accommodate the new Civic District. These changes will integrate the areas at Esplanade Park and Empress Place and could potentially make for a closer race at this year’s F1 Singapore Grand Prix. Explore the changes in the map below.

Light up flags for a night time race

The Singapore Grand Prix will see the use of electronic flag displays - ‘digiflags’ which come in handy this night race. They are controlled by officials at each marshal’s post and mounted around 300 metres apart on fencing along the street circuit.
