Tower Bridge Walkway, London, England, United Kingdom

In April 2008 it was announced that the bridge would undergo a 'facelift' costing £4 million, and taking four years to complete. The work entailed stripping off the existing paint down to bare metal and repainting in blue and white. Each section was enshrouded in scaffolding and plastic sheeting to prevent the old paint from falling into the Thames and causing pollution. Starting in mid-2008, contractors worked on a quarter of the bridge at a time to minimise disruption, but some road closures were inevitable. It is intended that the completed work will stand for 25 years.
The renovation of the walkway interior was completed in mid 2009. Within the walkways a versatile new lighting system has been installed, designed by Eleni Shiarlis, for when the walkways are in use for exhibitions or functions. The new system provides for both feature and atmospheric lighting, the latter using bespoke RGB LED luminares, designed to be concealed within the bridge superstructure and fixed without the need for drilling (these requirements as a result of the bridge's Grade I status).
The renovation of the four suspension chains was completed in March 2010 using a state-of-the-art coating system requiring up to six different layers of 'paint'.
