1. Beam bridge: Is basically a horizontal structure that is resting on two piers, one at each side. 2. Arch bridge: It is a semicircular structure with abutments on each end 3. Suspension bridge: Its one where cables (or ropes, or chains) are strung across the obstacle and the deck is suspended from these cables. 4. The Cable Stay Design (also Suspension): In the Cable Stay Design the Cables doesn't go from tower to tower but go directly to the deck, supporting it in a diagonal way.

Human beings have used new technology to solve problems and ease their physical burdens, and bridges are technological tools that aim to solve the problem of crossing an obstacle in such a way as to shortening the effort and time needed to do so.

King of the Thames

The Tower Bridge is a symbol of London,UK.

In the late nineteenth century several bridges crossing the Thames, but all were to the west. London, however, grew to the east and its neighbors demanded a new step.

 In 1876 the Corporation of London created a special committee for the construction of a bridge or underpass. The committee convened public competition to design a tunnel or a bridge. Two years later, the project was approved by the City architect, Horace Jones, who proposed a bridge of scale. These types of bridge have two sections that are raised by the operation of gears, counterweights and motors, located at the ends.

Also this bridge has two pedestrian and one vehicular road. At the top there are two pedestrian paths that are accessed by stairs or elevator. <span style="color: #800080; font-family: 'Comic Sans MS',cursive; font-size: 110%;">To raise each of the arms, the builders installed two steam engines,whose power reached the 360 HP. The steam generated by these machines was bonbeado two similar teams, also of 360 hp and 6stored in batteries. This system was later replaced by anelectro-hydraulic mechanism designed by BHA Crowel House.
