The mass deployment of 110,000 riot police, soldiers and medical emergency staff was ordered as France remains on high alert for terrorist attacks.
The annual Bastille Day military parade, which salutes the attack on the Bastille fortress during the French Revolution on July 14, 1789, will take place on Saturday, followed by World Cup final on Sunday.
Paris’s police chief Michel Delpuech said on Thursday the city is mobilising 12,000 police officers, 1,600 soldiers and 3,000 rescue workers.
The World Cup Final – which will see Didier Deschamps’s men face Belgium in Russia – is expected to see hundreds of thousands of revellers take to the streets on Sunday.
As many as 90,000 fans could gather under the Eiffel Tower to watch their team take on Belgium.
The crossover between Bastille Day and the World Cup final causes complication for law enforcement in the country, which remains on high alert for terrorist attacks.
French Interior Minister Gerard Collomb said: “We’ve never had three days like we’re about to have.”
The 2016 terrorist attack in Nice is still rife in people’s memories when sadistic Isis jihadis killed 86 people and wounded 458 by driving a truck into crowds celebrating Bastille Day.
In 2015, Isis militants killed 130 people in attacks that struck eight locations across Paris, including outside the Stade de France stadium.
The interior ministry added: “Everything is being done so the French can live these festive moments with peace of mind, despite the terrorist threat, which remains at a high level.”
Mr Collomb has issued strict orders that open viewings can only happen if entry points are monitored.
According to the Guardian: “If France wins, more than a million people are expected to flock to Paris’s most famous avenue, the Champs-Élysées.”
Hundreds of thousands of people headed to the Champs-Élysées after France beat Belgium in a semifinal last Tuesday.
Early Wednesday morning, police fired tear gas after protesters threw items at officers.
Michel Delpuech said cars would be prohibited from entering the Champs-Élysées if France were crowned World Cup champions.
He said: “The goal is to avoid what we saw in 1998,” when France won the final and “thousands of people attempted to reach the city centre by car, leading to three crashes and one person’s death.”
