Recently, a life-cycle cost(LCC) analysis is addressed for determining optimal, cost-effective design of infrastructures from the standpoint of the value engineering. The design paradigm for the infrastructures has gradually shifted from the initial cost-effectiveness to the LCC effectiveness. These recent researches of cost-effective life-cycle engineering based on the concepts and methods of the LCC have dealt with grand bridges and structures on highway. The LCC of structures on national highway could be overestimated using the LCC analysis which is applied to the grand bridges. This paper presents the LCC analysis approach of the structures on national highway using maintenance data which had been actually performed for ten years. The LCC approach proposed in this paper may be expected to be effectively used for rational LCC evaluation of the structures on national highway.
