Tower Bridge - of the most famous London attractions & over a hundred years elderly, the Tower Bridge with its twin drawbridges, or bascules, each weighing about one,000 tons have been raised more then half a million times since it was built. It takes only 90 seconds for the bascules to be raised with electric motors which replaced the elderly steam engines.
Tower Bridge is of the most ingenious examples of Victorian engineering. The lifting bridge was designed in 1884 to permit giant ships to pass unobstructed along the Thames. It is still raised & lowered or times a day & is as awe-inspiring today as it was when it was first built. The bridge also houses an excellent exhibition about the history & mechanics of the bridge & offers fantastic views of the city from its high-level walkways.
