<p>Aging bridge networks pose significant risks to safety in transportation, economic sustainability, and cultural preservation, especially in situations where limited resources curtail the application of advanced civil engineering in monitoring systems. The purpose of this study is to come up with a systematic approach to integrating careful visual inspection and the MCDM method to evaluate the structural health and to rank rehabilitation options along with heritage arch bridges. The methodology will utilize a systematic rating system to document deterioration indicators, including cracking, spalling, and damage caused by environmental factors, as well as structural, functional, ecological, social, and economic aspects. Such qualitative observations are fed into an MCDM model to give reasonable, unbiased suggestions. The model was verified on a stone arch bridge in Pune, India, built in the mid-nineteenth century. Under constant weather conditions, site inspections provided patterns of damage, and scoring was done by evaluating these damages against the established predetermined parameters. The analysis yielded the overall bridge health index of 4.33, which means that the structure is located in the crisis category, suggesting that reconstruction is the best intervention option. As evidenced in the results, visual inspection supplemented with MCDM can be used reliably to determine vulnerabilities and can be used to give open and defensible advice on maintenance planning. The implementation of the approach is a cost-competitive, flexible means of operational management of any bridge infrastructure, especially in areas where high-cost structural health monitoring systems are inaccessible.</p>
