Abstract: The aim of this research is to analyze the replacement of concrete bridges with precast concrete bridges, which could potentially lead to faster construction, thinner slabs and a more durable life. Precast concrete bridges also provide longer construction seasons throughout the year and reduce the duration of construction while maintaining roads or rebuilding bridge. Life Cycle Cost Analysis (LCCA) of precast concrete bridges with the traditional method by comparing the initial cost of precast concrete bridges with the traditional casting method, construction methodology, materials used, environmental impacts, recurring costs, maintenance costs, life-time assessment and life expectancy is discussed. Moreover, the traditional method is essentially to carry out all on-site activities, i.e. casting bridges on-site, curing bridges and then opening them up for traffic use. All these traditional methods can be eliminated if precast concrete bridges are used. The results expected from this study will identify how feasible it is to replace traditional bridge casting with precast concrete bridges in terms of cost, time and life expectancy
