Urban bridges have a direct impact on public safety, they are crucial components of the transportation system that require extra care. These structures, in contrast to highway bridges, frequently experience faster degradation due to increased traffic volumes, which are made worse by overloaded cars. Proactive management techniques, such putting in place vehicle weight limitations (VWRs) to reduce structural concerns, are necessary to address these issues. This study highlights how crucial precise traffic load modeling is to preserving the durability and reliability of municipal bridges. By using structural health monitoring (SHM) sensors and weigh-in-motion (WIM) devices, engineers may evaluate traffic patterns in real time and adjust load models to match the real situation. The study also looks at extrinsic elements that jeopardize bridge integrity, such as soil subsidence and pressures brought on by humans. Alongside developments in smart infrastructure, such as intelligent transportation systems (ITS) and next-generation 6G connectivity, which improve traffic management and minimize wear, new materials like ultra-high-performance concrete (UHPC) are being investigated to increase durability. The results highlight how crucial adaptive techniques are to keeping urban bridges safe and operational in the face of growing demands. These tactics include dynamic load modeling, ongoing structural examination, and incorporating developing technology.
