The Turkish Grand Prix was canceled just six weeks after entering the Formula 1 calendar and replaced by a second race in Austria.
But Turkey has now become unworkable after being put on the UK’s travel red list of high-risk countries.
Instead, the Styrian Grand Prix will take place at the Red Bull Ring from June 25-27.
This date was originally scheduled for the French Grand Prix, which has now been moved a week earlier to June 18-20.
The move means there will now be races over three consecutive weekends – the French Grand Prix at Paul Ricard, followed by the Styrian Grand Prix and then the Austrian Grand Prix, both on the same track.
F1 President Stefano Domenicali said: “We were all looking forward to racing in Turkey, but travel restrictions in place prevented us from being there in June.
“F1 has shown once again that it is capable of reacting quickly to developments and finding solutions and we are delighted to have a double header in Austria which means our season remains at 23 races. “
F1 has a series of protocols aimed at minimizing the risk of the spread of Covid-19 and claims to have performed 17,000 tests this year with only 15 positive cases, a rate of 0.1%. He says it “will continue to operate in a way that protects the safety of our staff and the communities we visit.”
A number of F1 insiders had hoped that the owners of the sport, Liberty Media, would not replace Turkey with another event.
Teams are already finding the combination of a record-breaking 23-race planned schedule and the movement restrictions placed on staff upon their return to the UK exhausting.
Some senior officials believe that it is not necessary to keep the number of races so high, when the sport has never had such a long season before.
But F1 believes that it makes sense to maintain the number of races that had been planned in the first half of the year as they are concerned about the viability of a number of late-season races.
For various reasons, there are uncertainties about the Grand Prix of Singapore, Japan, United States, Mexico, Brazil and Australia.
These races currently include the full sport calendar for October and November.
There are financial implications involving both sponsors and broadcasters that would affect F1’s finances – and the prizes paid to teams next year – if the number of races drops too far.
Brazil and Mexico are of concern as the scale of the pandemic in those countries means F1 may think it can’t justify going.
The doubts about Singapore, Japan, the United States and Australia are more related to the travel restrictions imposed on foreign visitors by these countries.
The reshuffle of the schedule means that former F1 driver Romain Grosjean will no longer be able to make his Demonstration in a Mercedes F1 car at the French Grand Prix, as it collides with the Indycar race at Road America in Wisconsin this weekend.
However, Grosjean’s test in Lewis Hamilton’s 2020 car is still expected to take place at Paul Ricard on June 29.
