Numerous numbers of bridges in cities are constructed on the river are subjected to decline as their lifespan is ended nonetheless, they are yet in practice. They are risky to bridge users. Due to heavy burden of vehicles, high water pressure, heavy rainfall these bridges might not get breakdown which in turn leads to disaster. So, these bridges need continuous observation. So, we are proposing a system which consists of a weight sensor, water level point contact sensor GSM module, and microcontroller. This system senses the capacity of vehicles, water level and pressure. If the load of the vehicle, water level and pressure on the bridges cross the threshold value then it produces the alarm through beeper. If the authority needs the live picture near the bridge for many purposes at any time, he can capture by using IOT application. For every alert from the bridge, we will play the voice messages regarding the events which exceed the threshold value from any bridge. If it is required, then the supervisor may allot the task to staffs for maintenance.
