Tower Bridge Walkway, London, England, United Kingdom

The high-level open air walkways between the towers gained an unpleasant reputation as a haunt for prostitutes and pickpockets; they were seldom used by regular pedestrians, as they were only accessible by flights of stairs and were closed in 1910. In 1982 they were reopened as part of the Tower Bridge Exhibition, an exhibition now housed in the bridge's twin towers, the high-level walkways and the Victorian engine rooms. The exhibition charges an admissions fee. The walkways, which are now enclosed, boast stunning views of the River Thames and many famous London sites, serving as viewing galleries for over 380,000 tourists who visit each year. The exhibition also uses films, photos and interactive displays to explain why and how Tower Bridge was built. Visitors can access the original steam engines that once powered the bridge bascules, housed in a building close to the south end of the bridge.
2008–2012 facelift
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.
