What is the Meaning & Definition of bridge

The term bridge is used to designate those constructions that are used to connect different spaces that otherwise could not be accessed. Through time, the design and engineering of bridges it has varied greatly, as well as also the material with which it is built and the utility, being some of them merely decorative. Traditionally, the main goal of the construction of a bridge has been overcome a type of geographical element preventing (or difficult) the traffic to find a course of water, a valley or a cliff. Thus, the bridge is built to connect the most extreme points of both sides and allowed then continue the transfer of different types of transport. While some bridges are constriuen for the passage of cars and trucks, others are exclusive to trains and railways and others allow in addition to human travel on foot. Finally, the famous Roman aqueducts are bridges designed and executed simply for the transfer of water. Bridges can vary significantly around the material used to make them (and some made of wood, others of stone, and many other modern metal like iron and steel). They can also vary greatly in the type of construction: while some are bridges that are set firmly on the ground to sort, others are suspended bridges in the air, perhaps most insecure but just as passable. As he has been said, many bridges have been constructed for ceremonial or symbolic purposes. Although these require the same effort in engineering and construction, they are seldom so traveled as those which are designed for the transfer of means of transport. The work of design, planning and construction of bridges is of great importance since the efficacy and the firmness of a bridge must be always secured. This is related to the weight that a bridge can support as well as also wear the same suffering through time, all issues which should certainly be taken into account when carrying out the design of a bridge.
