An enormous number of people made the journey to London in a bid to pay their respects to Queen Elizabeth II.
But shortly before 9.30am on Monday, London City Hall confirmed that all public viewing areas are full.
A statement on Twitter said: “All procession viewing areas are now full. There is no entry to any new arrivals.
“Please follow the advice of stewards and police. If you are in the area or about to arrive, use the dedicated walking route to Hyde Park to watch Her Majesty The Queen’s state funeral and procession.”

It comes despite thousands of mourners missing the funeral due to rail disruption.
All lines between Paddington in west London and Reading in Berkshire were blocked because of damage to overhead electric wires, Network Rail said.
Services run by GWR, Heathrow Express and the Elizabeth line were disrupted.
Passengers on a GWR train due to run to Paddington were told by a member of staff using the public address system: “My sincerest apologies for the delays on such an important day for the country.”
Mourners travelling to the funeral events in Windsor from Paddington were also affected.
The Royal Family, including Prince George and Princess Charlotte, will be among the 2,000 people gathered at Westminster Abbey to remember the late monarch on Monday morning, before a committal service at Windsor Castle.
They will walk in procession behind the coffin as it is carried through the Gothic church by the military bearer party.
The King and the Queen Consort will walk immediately behind the coffin, followed by Princess Anne and Vice Admiral Sir Tim Laurence, Prince Andrew, Prince Edward and Sophie, Countess of Wessex and Prince William and Kate, Princess of Wales.
George and Charlotte will walk with their parents in a side-by-side in formation, followed by their uncle and aunt, Prince Harry and Meghan Markle.
Queen Elizabeth II's coffin will be taken in a grand military procession from the Palace of Westminster to Westminster Abbey for the funeral at 11am.
