Huge queues have formed along the banks of the River Thames, as people wait to pay their respects to the Queen. Her lying-in-state will continue 24 hours a day until 06:30 BST on Monday 19 September - the day of the funeral. Here's what you need to know before joining the queue. How long will I have to queue? The queue is about five miles long, stretching to Southwark Park and is currently at capacity. It has now been paused for at least six hours and government has advised people not to attempt to join it until it re-opens. For those already in the queue, the estimated wait time is about 14 hours. The government has published a live queue tracker for people to follow on YouTube. People queuing are being warned they will need to stand for many hours with little opportunity to sit down, as the queue is constantly moving. The maximum length the queue can be is 10 miles - with 6.9 miles from Westminster to Southwark, and a three-mile zigzag queue in Southwark Park. Where do I join the queue? Check the tracker to see where the back of the queue is. People should receive coloured wristbands as they join, so they can leave for a drink, or to go to the toilet, and then return. Those in the queue are asked not to attempt to save a place for someone else, or leave personal items unattended, or put up tents. Once people get towards the front of the queue, they will pass through Albert Embankment and then be directed across Lambeth Bridge, into Victoria Tower Gardens, towards Parliament. They will have to go through airport-style security before entering Westminster Hall, inside the Palace of Westminster. Where can I go to the toilet while queuing? There are more than 500 portable toilets at various points along the route. Local venues and museums - including the Southbank Centre, the National Theatre, BFI Southbank and Shakespeare's Globe - will stay open for extended hours and in some cases for 24 hours, for people to use their facilities. Cafes and other local businesses are also expected to open for extended periods.
