The Turkish Grand Prix was canceled just six weeks after it was put on the Formula 1 calendar and replaced by a second race in Austria.
But Turkey has now become unfeasible after being included on the UK red list with a high risk for travel.
F1 will instead run in the Red Bull Ring from June 25-27.
That date was originally scheduled for the French Grand Prix, which has now been moved to 18-20 a week earlier. June.
The move means that the races will take place for three consecutive weekends – the French Grand Prix at Paul Ricardo, 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 the existing travel restrictions meant we couldn’t be there in June.
“F1 has once again shown that it can react quickly to developments and find solutions, and we are thrilled 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 spreading Covid-19 and says it has conducted 17,000 tests this year with only 15 positive cases, at a rate of 0.1%. He says he will “continue to work in a way that protects the safety of our staff and the communities we visit.”
Numerous F1 insiders had hoped that the owners of the sport, Liberty Media, would not replace Turkey with another event.
The teams are already exhaustively finding a combination of a record schedule of 23 races and restrictions on movement imposed on staff when they return to the UK.
Some seniors believe there is no need to hold such a high number of races, when the sport has never had a season before.
But F1 thinks it makes sense to keep the number of races planned for the first half of the year, as they have concerns about the viability of a number of races in the late season.
For a variety of reasons, there are uncertainties surrounding the Grand Prix of Singapore, Japan, the United States, Mexico, Brazil and Australia.
Those races currently contain the entire sports schedule for October and November.
There are financial implications that include sponsors and broadcasters that would hit F1’s finances – and the cash winnings that will be paid out to teams next year – if the number of races falls too far.
Brazil and Mexico are worrying because the scale of the pandemic in those countries means F1 may feel it can’t justify going there.
Doubts about Singapore, Japan, the US and Australia are more related to travel restrictions imposed by those countries on foreign visitors.
