Tower Bridge in London is one of the most famous bridges in the world and is one of the most popular tourist attractions in the UK. The lift bridge stretching across the River Thames, connecting Soutwark (on the north) and the City of London (on the south). Tower Bridge consists of a 244 m-long bridge and two towers as high as 65 m. Both the bridge tower adjoined at the top by two runs (walkway) are side by side, as high as 44 m above the surface of the water when the river was high tide.Tower Bridge was built in 1886 based on the design of an architect named Sir Horace Jones, and took eight years to complete. This bridge tower section has a Victorian Gothic style of architecture with a grayish color, harmony with the building from which its name is derived. The bridge was officially opened on June 30, 1894 by the Prince of Wales (King Edward VII) and his wife, Princess of Wales.One of the most unique of Tower Bridge is the bridge is cut in the middle so as to produce the two sides. Two sides of the bridge can be raised up to 86 degrees, which allows water traffic beneath it, especially ships with tall columns, can pass. This was the initial idea underlying the design of this bridge can be lifted, as a solution for ordinary bridges impassable tall ships.In ancient times, Tower Bridge can be lifted up to nearly 50 times per day (18,250 times / year), but currently only about 1000 times a year. Mechanisms in the removal of the bridge are done with hydraulic systems, while in appointment setting, performed through signal communication between the bridge operator and large ships that will pass. The computer system installed in 2000 to control the removal and reduction in the central part of the bridge from a distance.
