Definition of bridge
A bridge is a structure providing passage over an obstacle without closing the way beneath. The required passage may be for a road, a railway, pedestrians, a canal or a pipeline. The obstacle to be crossed may be a river, a road, railway or a valley.
In other words, bridge is a structure for carrying the road traffic or other moving loads over a depression or obstruction such as channel, road or railway.
A bridge is an arrangement made to cross an obstacle in the form of a low ground or a stream or a river without closing the way beneath.

Disadvantages:
When the soils beneath a footing are not capable of supporting the weight Of the structure above the soil, bearing failure occurs. The foundation Shifts or sinks under the load, causing structure movement and damage
