Bascule Bridge - Tower Bridge

Tower Bridge

Tower Bridge across the Thames in London is a famous bascule bridge. Originally, Tower Bridge was a hydraulically operated bridge, using steam power from coal-burning boilers to pump river water into six hydraulic accumulators so that power was readily available when required. The water for the boilers was provided by a well. The hydraulic accumulators powered the bascule engines, which raised and lowered the bascules. Today, the bascule mechanism is driven by oil and electricity rather than by water and steam.

Famous quotes containing the words tower bridge, tower and/or bridge:

    Culture is a sham if it is only a sort of Gothic front put on an iron building—like Tower Bridge—or a classical front put on a steel frame—like the Daily Telegraph building in Fleet Street. Culture, if it is to be a real thing and a holy thing, must be the product of what we actually do for a living—not something added, like sugar on a pill.
    Eric Gill (1882–1940)

    What did it matter where you lay once you were dead? In a dirty sump or in a marble tower on top of a high hill? You were dead, you were sleeping the big sleep, you were not bothered by things like that. Oil and water were the same as wind and air to you.
    Raymond Chandler (1888–1959)

    Crime seems to change character when it crosses a bridge or a tunnel. In the city, crime is taken as emblematic of class and race. In the suburbs, though, it’s intimate and psychological—resistant to generalization, a mystery of the individual soul.
    Barbara Ehrenreich (b. 1941)
