This paper review conditions of concrete bridge by taking visual inspection and non-destructive test. In India most of bridges was constructed after 1950. So, regular inspection of bridge is necessary. However, various factors such as large infrastructure development, the growth of population, has led to accelerated to detection of damage. Hence heavy traffic, the bridges are subjected to very high dynamic loading, to avoid Collapse Bridge it is mandatory to assess the conditions of existing bridge or health monitoring of bridge. Through this paper we recommending corrective measure for operation and maintenance. NDT method is to be use for verification of visual inspection in bridge management where measure damage occurred in the structure but cannot determine by visual. These techniques will allow inspector to locate damages earlier before any possible tragedies just like mahad bridge collapse in India, there exists a correlation between results of non-destructive test and condition states on visual inspections. There are many methods for non-destructive test (NDT) but every method has its own boundaries and which mean the method cannot afford an accurate and consistence result for difference cases and to detect different defect. The study also show that Ultrasonic pulse velocity test is the ideal NDT method to predict the deterioration in the structures and to determine the service life of the structures. The concept of non-destructive testing is to obtain material properties of in place specimens without the destruction of the specimen or the structure from which it is taken.
