Bridges are the lifelines for public, and most of the road bridges in India were not designed for the vehicular loads and their speed that they are currently subjected to. As construction of new bridges involves Nation’s huge economy, structural health monitoring of the existing bridges will help in terms of safety and economy. In Chennai City, there are many old road bridges, once functional, and are critical life lines, which are in need of SHM for the safer public usage. This paper expounds on the need for SHM on road bridges built across Cooum and Adyar Rivers in various zones, along with a case study on a RCC road bridge constructed across Cooum River. A live load testing was conducted on a single span of the bridge to study the flexural responses of the girders. The strain histories obtained from the analytically investigated model of the loaded bridge were compared with the field measured strain data, and necessary improvements were done on the model to measure the effective stiffness property of the girders. This investigation has helped in providing recommendations on retrofitting applications of the bridge components ensuring public safety and the continuous serviceability. Thus, SHM of the road bridges will increase the life of the structure and serving public in a longer run.
