Abstract
The Italian heritage of bridges and viaducts is very dated. Except for the historical bridges of pre-industrial origin, most of the bridges and viaducts were built before 1982, with a very high percentage after the second world war. The intrinsic structural fragility is therefore evident, which is complex to stem above all by local authorities. Currently, the territorial and local road operators are required to plan the maintenance of bridges according the current regulatory framework, but due to a shortage of personnel and reduced availability of funds, this objective requires the identification of adequate strategies. With the issuance of the "Guidelines for the classification and management of risk, the evaluation of safety and the monitoring of existing bridges" a new multilevel approach - based on risk and attention classes evaluation - was introduced for management of road bridges. In this scientific work the case of the Municipality of Rome will be illustrated, deepening the bridge management system already implemented. A benchmark between road operators and a "gap analysis" for the adoption of the new Bridge Guidelines will also be illustrated.
