Well-wishers have been advised to arrive in plenty of time as the Royal Family heads to Norfolk for their Christmas celebrations.
The King and Queen are expected to be hosting a larger-than-usual gathering at Sandringham over the festive period.
The road next to the visitor centre at the estate will be partially closed between 7am and 1pm on Christmas Eve, Christmas Day and New Year’s Eve.
Thousands of people are expected to fill the public viewing area and police officers will be on duty around the estate.
The King and Queen will be joined by Prince William and Princess Kate and their three children George, 10, Charlotte, aged eight and Louis, aged five.

The Duke and Duchess of Edinburgh and their children Lady Louise, 20 and James, Earl of Wessex, 16, will also be in Norfolk, along with the Duke and Duchess of York and their family - Princess Beatrice, her husband Edoardo Mapelli Mozzi and daughter Sienna, aged two; and Princess Eugenie, her husband Jack Brooksbank and their sons August, aged two and Ernest, who was born in May.
The Duke and Duchess of Sussex are expected to stay in the US with their children Archie, aged four and Lilibet, aged two, but Queen Camilla's two children and five grandchildren are set to join the Sandringham party.
Most guests will arrive on Christmas Eve when cake and sandwiches with the crusts cut off are served at 4pm sharp.

Christmas Day begins with a breakfast of fruit and toast in their rooms for the ladies while the men of the family have bacon, eggs and kippers in the dining room.
Then the Royals set off on a walk from the house to morning service at the Church of St Mary Magdalene.
This is the moment when thousands of well-wishers can greet them and the Christmas service is broadcasted through a PA system.
They will then return to Sandringham House for a traditional dinner of Norfolk turkey with vegetables grown on the estate.
