<p>In the maintenance of existing bridges, a bridge life-extending repair plan has been formulated. Recent years, the importance of risk management has been recognized in view of severe damage due to natural hazards. Natural hazards cause serious disruption to societies and their transport infrastructure network. Therefore, it is necessary to formulate the life-extending repair plan considering connectivity of road network. In this study, an effective maintenance plan of the bridges is simulated in consideration of the connectivity of the network by the increased risk of damage at the time of disaster due to deterioration of the bridges. Simulation results show it is possible to formulate a life-extending repair plan that can secure a more robust network with leveling the annual repair cost.</p>
