Bridge vibration control is an important issue whose purpose is to extend the structural service life of bridges. Normally, the bridge is modeled as an elastic beam or plate subject to a moving vehicle. However, the moving truck on a bridge is a complicated problem that must still be researched. In this paper, wepropose a new method, to overcome the huge load in the bridge a load cell is used at the entry which will monitor the load continuously at both ends. To escape from the heavy water flow bridge vibrations alarm is used and it is connected with the water over flow sensor which will convert the heavy water flow signal into electrical signal and this electrical signal will make an alarm and close the gate of the bridge. When both the problem occurs at same time or at different time an alarm is generated and the bridges will automatically closed.
