London's iconic Tower Bridge is set to have a state-of-the-art energy-efficient lighting scheme installed.
The Mayor of London, Boris Johnson, brokered a public-private finance deal between the bridge owners, City of London Corporation, London 2012 Sustainability partners EDF and GE to carry out the upgrade.
The installation will feature GE LEDs and light-guide cabling to enhance the bridge's features - such as its gothic turrets, central aerial walkway and suspension chains - in colours sensitive to its listed building status.
The lighting system will be customisable, allowing for varying colours and intensity of light, so it will be possible to create spectacular displays on the bridge during major events like the London Olympics.
Currently Tower Bridge has traditional, static flood-lighting.
The use of LED technology will reduce the energy consumption of the lighting system by an estimated 40 per cent.
Urban lighting specialist Citelum has been appointed to design the scheme.
EDF Energy will become the lighting electricity supplier for Tower Bridge and will match every unit of electricity that it supplies to Tower Bridge with power generated from low carbon sources.
Subject to planning permission, work could start by September and be completed by spring 2012, in time for the Olympic and Paralympic Games.
