Tower Bridge will be closed to vehicles from October for three months to allow for structural repairs and maintenance work. Around 21,000 vehicles use the 122 year old landmark every day.
Pedestrians will still be able to use the famous Thames crossing on all but three weekends of the work, when a free ferry will operate instead. The viewing gallery along the walkways of the bridge will also remain open.
Nearby Tooley Street is already closed eastbound until 2018 to allow Network Rail's rebuilding of London Bridge station, and the AA president Edmund King claims drivers who have been frustrated by congestion from new cycle lanes will suffer more misery.
The City of London Corporation says the decision to close the bridge to vehicles in the Autumn hasn't been an easy one.
