Weight limits London bridges

I seem to remember length restrictions spread liberally about. I used to take trailers from FX to Covent Garden & the only legal way for that part of London was M25, M4 all the way to Hyde Park Corner hang a right ,thru Victoria & over Vauxhall Bridge. I suppose that it was a night-time truck ban. But getting tangled up on the daytime traffic on the South -Side is not my idea of fun…To be there at 0800 Kindle must have left FX before 0400. It sounds like a crane job.
