This paper deals with a solution to rectify the problem of corrosion in steel girder bridges. The problem arises due to electrochemical reactions occurring inside the structure on the surface of the steel. These reactions result in oxidizing the steel and eventually corroding it. For controlling such problem a mechanism is developed using de current parallel wire system. This mechanism is based on parallel connection circuit principle i.e. current always uses the path with low resistivity and it is also emphasized to use smart material to produce DC current to be supplied in parallel wire system. How to install and design the Parallel wire system to control corrosion is illustrated in this paper. This mechanism can be used in various types of steel structures like bridges, and results in increased reliability and durability of such structures.
