5pm on November 9th: To mark the end of the Lord Mayor's Show and the beginning of a new mayoral year, London's newly confirmed Lord Mayor will launch a splendid fireworks display over the river.
It's one of London's most spectacular annual displays and you'll be able to see the fireworks for miles, but for the best view of all head down to the riverside between Waterloo and Blackfriars Bridges, either on Victoria Embankment or on the South Bank. All the roads and both side of Waterloo bridge will be closed to traffic so there's plenty of room. Blackfriars Bridge is also closed on the northbound side, so there will be room for everyone.
You can expect the display to last 10 - 15 minutes and the roads to reopen at around 6.30.
