Formula One's governing body has said it is confident Saudi Arabia will be ready for its grand prix debut next month after media reports highlighted the amount of track work still to be completed.
The floodlit night race along the Red Sea shore in Jeddah is scheduled for Dec. 5 as the penultimate round of the championship.
Depending on results in Brazil and Qatar, Saudi Arabia could be a title decider between Red Bull's Max Verstappen and Mercedes' Lewis Hamilton. Verstappen leads Hamilton by 19 points with four races remaining.
"The FIA and F1 are getting daily updates of where things are at and it's progressing very, very quickly," FIA race director Michael Masi told reporters after last weekend's Mexico City Grand Prix.
