According to the Crown Chronicles:
Londoners and its visitors are being asked to line the banks of the River Thames and applaud The Queen as she becomes the longest reigning Monarch on 9th September.
A small river pageant will take place, reminiscent of the Diamond Jubilee River Pageant…
The route begins at Tower Bridge, where the bridge will be raised in honour of the occasion…eventually reaching the Houses of Parliament. The boats will sound their horns to rouse the crowds, and HMS Belfast will sound a 4-gun salute as they glide past. The National Anthem and three cheers will conclude the flotilla.
