A map has revealed the extremely long queue hundreds of thousands of people are waiting in to bid farewell to Queen Elizabeth II - with some people standing in line overnight.
The map, which was released by the UK government, shows the approximately 2.6-mile-long line mourning Brits will have to wait in to pay their respects to their beloved Queen.
"Please note that there will be a queue, which is expected to be very long. You will need to stand for many hours, possibly overnight, with very little opportunity to sit down as the queue will be continuously moving," the government said.
Government officials said they could not put a precise figure on how many would want to file past the Queen's coffin, but around 750,000 people were expected and authorities have warned wait times could be as long as 35 hours.
During the Lying-in-State period, Her Majesty's closed coffin rests on a raised platform, which is called a catafalque, inside Westminster Hall in London.
Members of the public attending will file past the catafalque to pay their respects to the Queen.
There is a live queue tracker to help people find the current location of the back of the queue.
The queue starts where Albert Embankment meets Lambeth Bridge in Central London, on the south side of the River Thames. From Albert Embankment, the queue continues along the south bank of the Thames.
More than 1000 volunteers are helping monitor the line and there are facilities along the way including public toilets, drinking water and first-aid stations.
Upon joining the queue, mourners will be given a coloured wristband that will be numbered and will allow them to briefly leave the queue to use a toilet or get food and drink.
Earlier on Thursday, Newshub reported that some royal fans had braved the rain and slept on the pavement overnight to secure their position in the queue, which could stretch for 10 miles, to gain access to Westminster Hall.
The British Film Institute will have an outdoor screen broadcasting footage of the Queen and her reign.
