The article presents a proposal of this System for both traditional and singular bridges whose objective is to provide the National Road Department with a tool to improve the management and conservation of bridges through preventive inspections focused on the detection of major pathologies and on strengthening future maintenance programs, optimizing the behavior of bridges and the allocation of resources. The System allows the conduction of the inventory and condition inspection of the bridges, using then logical algorithms to obtain the severity index of the bridges, while it modernizes the data collection and its subsequent consultation and exploitation, using a web application to facilitate the access to information.
