Plans to shut Tower Bridge to pedestrians for three weekends have been revised and the bridge will now only be closed for a single day.
The bridge has been closed to motor traffic since 1 October and was due to be shut to pedestrians for the next three weekends.
The City of London Corporation, which is carrying out the works on the bridge, has now revised its plans so that only a single day's closure is required.
On Sunday 4 December a free ferry service will operate between Butler's Wharf Pier and St Katharine's Pier.
The ferry will run every 15 minutes between 8am and 4pm.
The bridge is due to reopen to all traffic at the end of December.
