Tower Bridge and the former City Hall.
It takes well under five minutes to raise each half (bascule) of Tower Bridge’s central stretch to allow large ships to pass.
When the Tower Bridge bascules are fully lowered, 18 tons is the weight limit of vehicles using the bridge. 86 degrees is the maximum angle each bascule can be raised.
