Tower Bridge, one of the great
symbols of London.
Around the middle of the 19th
century the volume of cross-river traffic meant a bridge close
to the Tower of London was needed. The capital's best-known
bridge, designed by Sir Horace Jones, was built between 1886
Two major piers were sunk into
the riverbed to support the construction and 11,000 tonnes
of steel were used for the framework of the towers and walkways.
The pioneering structure was then clad in Cornish granite
and Portland Stone, to protect the steelwork and give the
bridge a fashionable Gothic appearance.
Its pinnacled towers and linking
catwalk support the mechanism for raising the roadway when
large ships need to pass through, or for special and historic
occasions. On its completion, Tower Bridge was the world's
largest and most sophisticated hydraulically operated bridge.
1976 the machinery was powered by steam, but now the hydraulic
machinery is electronically operated.
When raised the bridge is 135
feet high and 200 feet wide. Once the bridge was opened five
times a day and now it still raises at least once a day.
