Tower Bridge Walkway, London, England, United Kingdom

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'.
Incidents
In December 1952, the bridge opened while a number 78 double-decker bus (stock number RT 793) was on it. At that time, the gateman would ring a warning bell and close the gates when the bridge was clear before the watchman ordered the lift. The process failed while a relief watchman was on duty. The bus was near the edge of the south bascule when it started to rise; driver Albert Gunter made a split-second decision to accelerate the bus, clearing a three-foot drop on to the north bascule, which had not started to rise. There were no serious injuries.
