Abstract: Bridges are ubiquitous in all societies and impact the aspects of personal, sociological, environmental, economic, ethnic, and artistic nature of these communities. The requirement for SHM arises because the properties of both concrete and steel are highly dependent on a large number of variables that are frequently difficult to anticipate in practice. The representative parameters chosen for monitoring the health of a structure can be mechanical, physical, or chemical. Regularly monitoring the condition and serviceability of bridges is essential for proper management and serviceability. SHM system have developed continuously evaluating and analysing working conditions of bridges, thereby repairs, supervision, and planning are also enhanced. This study reviews SHM systems technology, communication and analytical approaches of remotely sensed data, and prognosis and earlier than usual frameworks to evaluate the existing procedure and emerging developments of bridge monitoring. This study seeks to consolidate case studies concerning structural health monitoring of numerous bridges utilizing a variety of techniques, efficiency assessment, and immediate alert systems from across the world.
