When you do the tourist thing at the bridge, they tell you that all

something approaching was likely to want the bridge opened.

But nowadays "at least 24 hours notice is required (in writing) for
Tower Bridge to lift". [from

If you are the master of a ship at sea, how can you make the request
in writing?
