Ministry of Land, Infrastructure, Transport and Tourism has encouraged proposing the Plan for life-prolongation of bridges of municipality until the March of 2014. About 180 municipalities in Hokkaido have proposed the plans. One of the authors of this paper has concerned with drawing up the plans. Several risks were raised out by looking into the plans. The risks are the difference of the maintenance cost between the municipalities, the absence of the professional engineer in the government of the municipality, and the many charges for the big-scaled bridges those had been managed by another authority. In this paper, the increased cost burden of the citizens in the municipalities due to quick population decline is focused as the serious risk. Also the relation between the number of the repair works for the members of bridges to the financial indexes of local governments are considered in this study.
